Orient Kamasu: A Guide To The Expert Diver’s Watch

Ever since Orient entered into the world of horology, it has received a great deal of respect in the community for producing high-quality, well-designed timepieces. All of their watches are made to honor Japan’s traditions and values. When you wear a Japanese watch, it is not just about wearing it to complete your newest fashionable look. Rather, you are actually wearing a piece of the country’s state-of-the-art technology, as is the case with the Orient Kamasu Red and Orient Kamasu Green models. 

Since they are both renowned Japanese brands, Orient watches are often mistaken for and even compared to Seiko watches. These two popular watchmaking brands have their own individual expertise in craftsmanship and different inspirations for producing watches. While Orient is part of the Seiko Group, they can still be considered two different brands as both are distinct when it comes to their operations and productions. 

Today, let us get into the Orient Kamasu, which is one of the toughest competitors to the Seiko SKX line. Read more about the Orient Kamasu’s exceptional qualities below and see just why it is one of the most popular timepieces today.

Get To Know The Orient Kamasu 

The Kamasu collection got its name from a distinctive sea creature, which is the Barracuda. Barracudas are big and fearsome fishes that are widely considered to be strong and inquisitive. Its long and thin body allows it to move rapidly, at speeds of around 36 mph (58 kph). Despite its terrifying appearance, the barracuda is an animal that receives utmost interest from professional divers around the world. The Orient Kamasu mirrors the fish’s features, specifically the teeth, which are mimicked through the sharp, triangular indices and handset of the Kamasu.

Since its release in 2019, the Orient Kamasu has thrived among the thousands of dive watches on the market. This is largely due to its superior elements, robust functions, and much more affordable prices compared to other brands. One of the Kamasu’s most remarkable highlights is its wearability. Most users cannot deny the fact how smooth the watch feels against the wrist. Its solid structure, with polished surfaces and no sharp edges, also gives off the impression of being very well-crafted.

One improvement Orient has made with the Kamasu is that it fixes the problems of old Orient watches, such as the lack of hand-winding, hacking movement, and poor hand functions. To address these shortcomings, Orient has equipped the Kamasu with a new automatic caliber that has increased accuracy of ±15 seconds from -25/+35  seconds accuracy per day and comes with a stops-second function. This caliber is used in a number of Orient Kamasu variants, including the Orient Kamasu Red Ref. RA-AA0003R19A, the Orient Kamasu Green Ref. RA-AA0004E19A, the Orient Kamasu Blue Ref. RA-AA0006L19A, and more. 

Orient Kamasu’s Specifications and Overview

An affordable price does not have to equate to low-quality and poor performance, and the Orient Kamasu is certainly proof of that. If you are planning to purchase a reliable dive watch, but you’re also working with a tight budget, look no further than the Orient Kamasu collection. Let us take a deeper look at its features and functions.

Case

  • Case Diameter: 41.8mm
  • Case Thickness: 12.8mm
  • Case Material: Stainless steel
  • Band Width: 22mm
  • Lug-to-lug Distance: 46.8mm

The case is a crucial component of any watch, and as such Orient devoted a great deal of effort into creating a good one for the Orient Kamasu. The Kamasu has a well-proportioned case size of 41.8mm and a lug-to-lug distance of 46.8mm with a 22mm lug width, so it can fit comfortably on the wrists of both men and women. Despite being a robust watch, the Kamasu is not too bulky or sporty and is just versatile enough to fit most fashion senses.

The case itself is crafted from corrosion-resistant stainless steel, with a brushed surface on top and well-polished surfaces on the sides. Stainless steel is not just anti-corrosive but is also impact-proof and able to withstand being accidentally knocked around, especially when used in everyday life. This durability makes the Orient Kamasu perfect for people with adventurous and outdoorsy lifestyles.

You will also notice the Kamasu’s properly curved lugs, tucked without reaching beyond the bottom of the screw-down caseback and with no harsh edges. The curved lugs sit well on the wrist, making the experience of wearing this watch a comfortable one that will not wear your wrist out throughout the day. In addition, the brand’s craftsmanship is shown in the gradual transition from having a brushed finish to a polished finish.

Using solid, dense materials like stainless steel can sometimes make a case too heavy for a wearer, especially for those with more petite wrists. However, the Orient Kamasu only weighs 6oz, or 170g, which is considered quite lightweight for a dive watch. Its overall case design is also reminiscent of a traditional sports watch, so people who prefer a sportier vibe will be quite satisfied with the Kamasu.

Dial

The dials in the Orient Kamasu come in a variety of colors like red, dark green, blue, and black. Perhaps the favorite of most watch enthusiasts is the wine red dial. The subtle gradient red dial with a ruby sunburst pattern shines impeccably when reflected under direct light. As mentioned, the triangular hour and minute markers, as well as the thick handset, are all inspired by the Barracuda’s sharp teeth. The second hand is the most distinctive of all, as it has a thin and long shape, stretching up to reach the minute markers and give an accurate reading of time. 

All Orient Kamasu watches are equipped with day and date displays that are nicely framed at the 3 o’clock position. You can see that the numerals in the date display are perfectly sized so as to be clearly visible regardless of the lighting conditions. LumiBrite technology is also added to indices, the handset, and the day and date aperture to give you a handy glow-in-the-dark watch when in the dark.

On the dial, you can find the brand’s name, logo, the water-resistance capacity of the watch, and the movement used, all delicately printed and spaced out. Unlike other dive watches, the Orient Kamasu does not come with a chapter ring that makes the dial appear larger, which is a rather unique choice. Instead, the Kamasu maintains a slim and lightweight appearance. 

Crown and Bezel

The Orient Kamasu also features a secure screw-down crown, placed in the customary 3 o’clock position. It has the Orient logo engraved into it, and is well-sized, just enough to be functional and easy to grip. The solid teeth-shaped ridges also help to provide the wearer a more secure hold on the crown. As with most Japan-made crowns, the crown of the Kamasu is waterproof, styled to have a long post and a direct o-ring gasket.

You might observe that the Orient Kamasu’s crown is slightly smaller compared to other watch brands. This is intentionally done so that the crown will not get in the way, scratching against the wearer’s wrist or getting easily damaged. The crown is often one of the most vulnerable parts of a watch, so Orient has designed it to be slightly smaller, with secure crown guards for extra protection.

In addition, the Kamasu also has a 120-click unidirectional bezel, a standard requirement for diving watches. It rotates counter-clockwise providing a safe and consistent pattern for divers to track their bottom times.

That said, if you are a professional diver, you know that the deeper you dive into the depths of the ocean, the darker it is, and the poorer your visibility will be. To ameliorate this, Orient has equipped the Kamasu with a luminescent bezel for accurate timekeeping even underwater. The 120-click function of the bezel also gives you better and more precise accuracy when aligning the zero markers at the bezel tip to the minute hand.

Bracelet

The Kamasu watches come in either stainless steel bracelets or rubber straps, depending on which model you choose to have. The stainless steel bracelets are water-resistant, corrosion-resistant, and able to withstand variations in temperature. They are easy to clean, and because of the material, do not soak up or retain any kind of sweat after thorough exercise. Stainless steel bracelets can be a little heavy on the wrist, but they are also very versatile and can blend well with almost any style. 

On the other hand, if you frequently engage in water activities, rubber straps might be preferable. Rubber is best used underwater. They are built from materials like silicone and polyurethane, which tend to be more lightweight, comfortable, and incredibly resistant to water. So if you intend to regularly exercise the Orient Kamasu’s capabilities as a dive watch, you might want to opt for a rubber strap.

Movement

An F6922 Caliber Automatic powers all the models under the Kamasu collection. It is a self-winding, automatic movement equipped with 22 jewels. This powerful in-house movement provides functions including hours, minutes, central sweep seconds, and a day/date indicator. Orient has claimed that the movement comes with an accuracy of -15 seconds to +25 seconds a day. Of course, this depends on the surrounding temperature, as well as the winding mechanism and the dial’s position.

The F6922 Caliber comes with a 40-hour power reserve, which is more than sufficient for a modern mid-range dive watch today. It also has self-winding and hacking features, which are great additions to this movement, since many other dive watches lack them. You just have to make sure to carefully maintain the accuracy of the watch by wearing it for at least eight hours a day and setting the date within the hours of 8:00pm and 4:00am.

Top Orient Kamasu Watches

1. Orient Kamasu Red RA-AA0003R19A

For a price of just $280 USD, you can get this beautifully masculine Orient Kamasu Red. The case of this watch is almost exactly like that of the Orient Ray II. It is 41.8mm wide and measures 46.88mm from lug to lug, large enough to fit well on any man’s wrist. The bracelet is made of 316L stainless steel with a push-button deployant clasp. The bracelet uses a solid, Oyster-style link, so you don’t have to worry about its durability. The jet-black bezel also stands out from the usual dive watches in the market, with dotted patterns in between bold white numerals.

The real highlight of the Orient Kamasu Red, however, is the red sunburst pattern on the dial, especially when positioned at the right angle, and with perfect lighting. At the 3 o’clock position is the day and date aperture, enclosed in a silver frame and placed against a white background. The color combination of red, white, and silver against the wine-red dial provides a good contrast, giving the wearer a clear and visible display.

2. Orient Kamasu Blue RA-AA0002L19A

Another variation of the Orient Kamasu is the model with a deep blue dial and bezel. Just like the other pieces, this can be bought for $280 USD. This price is a great deal for a dive watch, especially given its top-notch features and functions. The Orient Kamasu blue has a 41.8mm size diameter, which is great for those who want a mid-sized watch with a comfortably lightweight profile for water activities. The contrast of its smooth silver finish and royal blue bezel and dial adds a level of class and elegance, so you could easily wear this watch to more formal suit-and-tie occasions as well.

As with other Kamasu watches, this Orient Kamasu Blue comes with a flat sapphire crystal. Sapphire is one of the hardest materials used in luxury watches. Not only is it scratch-resistant, but it is also durable enough to withstand impacts, cracks, and breaks, unlike glass or plastic materials. The use of sapphire gives the dial a great deal of protection.

3. Orient Kamasu Black RA-AA0005B19A

The Orient Kamasu Black RA-AA0005B19A is the latest addition to the Kamasu collection. Despite looking strikingly different from most other Kamasu models, it retails at the same affordable price of $280 USD, making this a piece worth checking out indeed. This model of the Orient Kamasu features gold accents on its bezel, indices, and hands set that contrast handsomely with the sharp black dial and strap. A slim profile highlights the entire case, giving it an air of sophistication that makes it a good match for any outfit and occasion.

This model has a different look than the others in this collection. It uses silicone as its strap material instead. Silicone is a good material for sports watches since it is highly resistant to low and high temperatures. It is also more flexible and does not hurt the wrist, especially when you are doing intense sports activities. The Orient Kamasu Black also uses an Ardillon buckle for the clasp, adding a classic and simple look that’s well-suited for men. This is a more traditional option for watchmakers who want to design an easy-to-wear watch. This kind of clasp only needs to be clipped onto the buckle and pinned securely on the wrist. It has a flatter profile, a more classic design, and is less expensive. One problem with this clasp is that the Ardillon buckle can sometimes come open while being worn, so wearers have to be careful with this watch to make sure it does not fall off unexpectedly.

4. Orient Kamasu Green RA-AA0004E19A

The Orient Kamasu Green RA-AA0004E19A is another best-selling timepiece for men. Just like the previous watches, it has a 41.8mm stainless steel case and 47mm lug-to-lug length. For a price of $280, it showcases a dark green dial with a beautiful sunburst pattern, which changes its color depending on the reflection of light. This timepiece also comes with a matching dark green bezel, with its 60-minute scale printed on it in a contrasting white hue. The Barracuda-inspired indices of the Orient Kamasu Green are generously coated with luminous material, which is very important for a dive watch, as it guarantees optimal readability even in dim lighting conditions. A substantial power reserve of 40 hours ensures that you don’t have to constantly wind this watch to keep it running.

Orient Kamasu vs Seiko SKX 

Anyone interested in the horology industry knows that these two lines of Japanese watches are always compared with each other. In fact, the Orient Kamasu and Seiko SKX are likely each other’s greatest competitors in the industry of watchmaking. They both set a high standard for entry-level dive watches in the market. 

Though Orient is part of the Seiko Group, it maintains itself as a distinctive brand, with its own unique timepieces and innovations. Although Orient watches tend to be of slightly inferior quality compared to Seiko timepieces, the Kamasu collection was specially designed to be an improvement on the old models, featuring cutting-edge innovation and top-notch craftsmanship. It is Orient’s crowning glory, both in terms of aesthetics and functions offered. Combined with the fact that it is available at a very competitive price, the Orient Kamasu’s superior aspects cannot be ignored by many watch collectors. So, how exactly does the Kamasu fare against the Seiko SKX?

Firstly, the case of the Seiko SKX has a polished finish, with slender curves and no sharp edges. It has a slightly larger case size of 42.3mm and offers a variety of colors for the dial. And to support the inner adventurer in you, it uses Seiko’s Hardlex crystal, which is proven to be resistant to everyday wear and tear, to protect the dial. An ISO-certified 200-meter water resistance capacity is another great feature that the watch possesses, as wearers can bring the Seiko SKX with them to poolside diving, swimming, snorkeling, and other such water activities.

The Orient Kamasu, on the other hand, is lightly brushed on the top. It features the Orient brand logo delicately carved into its case back. A closer look at the dial reveals to you a beguiling and subtle gradient texture, which is great for those who don’t want a dial with just one solid color. To protect its dial, it uses a sapphire crystal, which is also known to be extremely scratch-resistant and is commonly used in durable watches. The Kamasu watches have a smaller case size of 41.8mm, so they can be worn more comfortably by both men and women. While the Orient Kamasu does not have an ISO rating, it does feature the same 200-meter water resistance, just like the Seiko SKX.

The movement used is also a big determiner in the competition between these two watches. The Kamasu’s Caliber F6922 is an innovative movement with features like hand-winding and hacking and features +25 / -15 seconds accuracy per day. The Seiko SKX, on the other hand, only provides an accuracy of +50/-20 per day and does not come with hand-winding or hacking functions. In terms of the accuracy of timekeeping and the robustness of the features offered, the Kamasu clearly wins this round.

Price is yet another deciding factor between these two models. Orient retails at a lower price of $280 USD, while the Seiko SKX can be purchased for an approximate price of $400 USD. Note also that the SKX collection has been discontinued; as such, prices may change depending on the independent seller you are dealing with.

Most people can tell you that Seiko SKX is a popular, historical, and established collection of dive watches. On the other hand, the Orient Kamasu is a perfect example of a new challenger, a risk-taker that gives you a better value for money. All of its watches are made to give a modern, youthful look for a wearer.

Final Thoughts

If you are planning to get yourself a practical and functional diver’s watch, the Orient Kamasu will definitely be a great pick for you. On the whole, it offers plenty of features for a very affordable price point. The sapphire crystal, 40-hour power reserve, hardy stainless steel case, robust Caliber F6922, handy uni-directional bezel, secure screw-down crown, and wide range of models available for your choosing are more than enough to justify the affordable $280 USD price. 

The Orient Kamasu will make for a great companion during your outdoor activities. Not only does it come with many useful functions to fulfill your every need, but its versatile look, which is not too sporty or bulky, also makes it great for everyday wear.
