Citizen NY0040: The Enduring Diver

If you are familiar with the world of watches, then you know that there is more to the industry than Swiss timepieces. Countries like Germany, Denmark, the United States, and others are becoming more and more known for their expertise in watchmaking. However, if there is one country that’s almost as well-recognised as Switzerland when it comes to horology, it would probably be Japan. Longstanding Japanese brands, like Seiko and Casio, are proof of how well the Japanese have mastered the craft. While it may seem like a competition, the watchmaking industry is a place of innovative cooperation and coexistence, and Citizen is the perfect embodiment of this. Many view this brand as the perfect mix of Swiss and Japanese craftsmanship, but we’ll get more into that later. If this has piqued your interest, then read on because we’ll be talking about Citizen Watches and in particular, their Citizen NY0040 model in this article. 

Citizen: A Brief History 

Citizen’s origin dates back to a little over 100 years ago in 1918. A jeweler named Kamekichi Yakamazi established a watch manufacturing firm called the Shokosha Watch Research Institute. The interesting thing about this firm is that Yakamazi was able to acquire Swiss machines and instruments for his company from watchmaker Rodolphe Schmid. This is where the idea of Citizen as a product of both Swiss and Japanese craftsmanship began.

A couple of years down the line, and the Shokosha Watch Research Institute changed their name to the one they’re still known for today: Citizen Watch Company. This change was brought about by an ambitious goal in which they hoped to equip every citizen in Japan with a watch produced by them. Just like any other origin story, Citizen also went through their fair share of triumphs and obstacles throughout the years. 

The Japanese manufacturer had a relatively strong start but certain unfortunate events happened, specifically the 2nd World War, which negatively affected the whole economy. While this was a devastating time for many individuals and businesses, it also became an avenue for a fresh start. After the war, Citizen decided to introduce themselves to the rest of the world under the name the Citizen Trading Company. This new moniker highlighted how their goals had shifted from being a Japanese-centric company to one that is more focused on showcasing their craft globally. 

One of the defining moments for Japanese watchmaking was the onset of the Quartz Revolution back in the 70s. Seiko is known to be the first brand to ever release a quartz watch and Citizen followed their footsteps just a couple of years later. This opened up countless opportunities for Citizen which eventually led to greater success and more milestones for the brand. From groundbreaking digital models to the first-ever solar-powered watch, the Japanese company has focused on developing their technology to become the renowned name they are today. 

Come the 21st century and Citizen has proved that they are not messing around. They’ve engaged in a massive expansion of their assets, purchasing well-known brands and watch groups like Bulova, Frédérique Constant, Arnold & Son, and more. The Japanese brand is also famous for its partnerships and collaborations with sports institutes, sports teams, and even Disney. When it comes to reputation, they are highly regarded today for their sustainable, eco-friendly, and reliable timepieces. 

All About the Citizen Promaster

The specific model we’ll be talking about in this article belongs to Citizen’s Promaster line. Before we delve into the Citizen NY0040 itself, let’s take a closer look at the Promaster collection. 

The Citizen Promaster is regarded as one of the best that the brand has to offer. It consists of a selection of sports (and diving) watches that showcase Citizen’s technological prowess. The Promaster was officially launched in 1989, although some argue that this line actually dates back to the late 1950s when the Citizen Parashock and Parawater models came out. Regardless, there were 3 different Promaster models released in 1989: the Promaster Aqualand, the Promaster Altrichron, and the Promaster Sky. These pieces were specifically designed for professionals who were constantly in harsh environments whether it be land, air, or sea. It was marketed as the result of Citizen’s unwavering research and innovations in the last few decades. 

Since then, this series has been home to numerous revolutionary pieces such as the Promaster Navihawk, the Promaster Amphibian, the Promaster Cyber Aqualand, and lots more. 

What is the Citizen NY0040? 

The Citizen NY0040, also known as the Promaster NY0040, was first launched back in 1997. It is a widely known model, especially within the watch community because of its distinctive physical features. Despite being released over 20 years ago, the NY0040 is surprisingly still being offered today, albeit with slight variations from the original. To the unfamiliar eye, this watch might seem like any other sports watch in the market, especially since it has aesthetic attributes similar to that of a typical diving model. However, there is definitely more than meets the eye with this timepiece simply because Citizen always manages to add a splash of Japanese workmanship to its pieces. Everything about the Citizen NY0040 is an expert Japanese take on sports watches, so you know it’s built to last. Let’s take a closer look, shall we?  

Citizen Promaster NY0040 Specs

Case Material: Stainless Steel

Diameter: 42mm

Case Thickness:12mm

Strap Material: Rubber (Urethan)

Movement: Automatic | Miyota Calibre 8203

Power Reserve: 45 hours

Water Resistance: 200 meters

Exterior: Case & Bracelet

The Citizen NY0040 actually comes in two variations — the NY0040-09EE and the NY0040-17LE — with the first sporting a mostly traditional black look and the second mostly in blue. Just like most sports watches, this model sports quite a rugged exterior but with an aura of professional class at the same time. It is a versatile piece that would look great with an everyday outfit or even a smart-casual ensemble.

The Citizen NY0040 comes in a stainless steel case that has a diameter of 42mm, a thickness of 12mm, and 20mm lugs. These numbers may seem intimidating but it is in fact an ideal size for a men’s diving watch. Furthermore, it also has a one-way rotating aluminium bezel in smooth matte black with a luminescent pip in lieu of the 60-minute marker. The material and the design of the gear-shaped edges of the bezel were chosen for optimal visibility and ease of use when underwater. 

Moving on, the dial is protected by mineral crystal glass which has scratch-resistant properties. On the rear of the watch is a solid caseback with engravings of the Citizen Promaster logo and other information regarding the specifications of the watch. One of the most distinctive features of the NY0040 is the position of its crown. In most watches, the crown is placed at the 4 o’clock position but this model has its crown on the opposite side at 8 o’clock. This was purposefully done to cater to left-handed individuals whilst also providing better comfort in general. 

Lastly, the Citizen NY0040 comes with a high-quality rubber strap which is perfect for the harsh conditions of diving. Bracelets and straps are very important things to consider, especially when you’re looking for a durable sports timepiece. Rubber is the usual choice of strap when it comes to dive watches, while leather and steel are not recommended. Another great thing about the NY0040’s strap is that it has no-decompression limits, making it incredibly durable at any depth. Overall, making use of a rubber strap for the NY0040 was definitely a conscious decision on Citizen’s part in order to promote better functionality and reliability. 

Dial

The focus on ease of use did not stop with the materials and exterior of the Citizen NY0040. Each and every component in the dial was also designed with readability and comfort in mind. If you are familiar with watches, all you need is a single glance at the dial to know that the NY0040 is indubitably a diver’s watch. As mentioned, the NY0040 comes in classic shades of either black or blue, with both variants sporting a matte finish to avoid reflective light glares. It follows a typical analog layout with big luminescent hands and hour markers in various shapes. You can also find a day and date display at 3 o’clock. This aperture is presented as a black background with red text to indicate the day and white text for the date, adding a splash of color that to the dial that makes for better readability. 

While most of the elements in the dial scream “diving watch”, it is also clear that Citizen kept the Citizen NY0040 versatile enough to be used both on land and underwater. It is a great option for people, especially divers, who don’t like changing their watches on a daily basis. 

Movement

The newest Citizen NY0040 is powered by a Miyota 8203 caliber automatic movement. It consists of around 21 jewels to reduce excessive wear and tear and has a frequency of 21600 beats per hour, which boasts a relatively high accuracy. Lastly, it has an impressive power reserve of 45 hours. 

Citizen NY0040 vs Seiko SRP367 Baby Tuna

The Citizen NY0040 is often compared with the Seiko SKX007 but, today, let’s switch it up by putting it against the ever-so-popular Seiko Baby Tuna. Both are renowned sports watches but today, we’ll see which is the better diver. 

Seiko SRP637 ‘Baby Tuna’ Specs

Case Material: Stainless Steel

Case Dimension: 47.5mm x 13.5mm x 50mm

Strap: Stainless Steel 

Movement: Automatic

Power Reserve: 42 hours

Water Resistance: 200 meters

Exterior

With a case diameter of 47.5mm, the Seiko Baby Tuna is definitely heftier than the Citizen NY0040. The Seiko Baby Tuna also looks a lot more robust and rugged compared to the NY0040, which leans towards a more classic sports watch style. Both are made from hardy stainless steel and have unidirectional bezels with luminous pips at the 60-minute marker. A key difference between the two, however, is that the Baby Tuna has a crown at 4 o’clock while the Citizen NY0040’s crown is at 8 o’clock. In addition, the NY0040 has a mineral crystal to protect the dial while the Baby Tuna makes use of Seiko’s patented Hardlex crystal. 

In terms of the strap, the Seiko Baby Tuna comes with a stainless steel bracelet while the Citizen NY0040 has a rubber strap. As mentioned, this is a crucial factor because some strap materials are more ideal for diving than others. However, it should be noted that the Baby Tuna has a clasp with a folding expansion feature which allows for a more snug fit around your wrist, even when you are wearing a wet suit.  

Dial

Moving on to the dial area, both models follow a standard dive watch layout with an analog display. Just like the Citizen NY0040, the Seiko SRP637 also has large, luminescent hands and hour markers. However, the Seiko Baby Tuna uses rectangular shapes while the NY0040 has mostly circular ones. Lastly, the Seiko model has a day and date window with a stark white background and black text while the NY0040 has one with a black background. 

Technical Specifications

When it comes to features and functions, it is safe to say that both are equally impressive. The two models each offer water-resistance of up to 200 meters and power reserves of over 40 hours. Both are also equipped with in-house Japanese calibers that follow automatic movements. 

Prices

This is probably where they differ most. The Seiko Baby Tuna SRP637 is priced at over $800 USD online today while the Citizen NY0040 retails at not more than $250 USD. 

Verdict

It is undeniable that both timepieces are excellent but, at the end of the day, it all boils down to what you consider worth it or not. In this case, I would have to go with Citizen NY0040 because it’s the more classic and sophisticated model between the two. It is an amazing diver’s watch but it’s also very versatile which means you can wear it on a variety of occasions. The best part is you get great functions and design without having to break the bank, as opposed to the Seiko Baby Tuna, which is considerably more expensive than the NY0040.
