Seiko Captain Willard: Reviewing One Of Seiko’s Most Unique Vintage Divers

Those who are familiar with Seiko will know that its extensive catalog has produced some of the best dive watches on the market. Seiko has an amazing reputation amongst enthusiasts and collectors because it is a true master of the horological craft. At present, the brand has hundreds of diving timekeepers in its portfolio, with many, like the Seiko Tuna or Seiko Samurai, even serving as horology icons.

One of Seiko’s most popular dive pieces today is the Seiko Captain Willard, which is known as a quintessential diver in the watchmaking world. In fact, the original Seiko Captain Willard is also referred to as the basis for all the Seiko diving watches that came after it because of its impressive, unparalleled qualities that were ahead of its time. With all that said, let us take a closer look at what the Seiko Captain Willard has to offer and figure out what all the hype is truly about.

Seiko Captain Willard: A Brief Background

The Seiko Captain Willard, also known as the Seiko 6105, was released back in 1968. This was around the same time as the Vietnam War, which is a historical event that is most often associated with the Seiko Captain Willard. However, contrary to popular belief, the Seiko 6105 was not actually used by many soldiers during the conflict. There is no historical evidence that the Seiko 6105 was sold or given to US troops during that time. Instead, it was the Seiko 5 that was a more popular choice amongst soldiers during that period.

That said, the Seiko Captain Willard quickly gained fame in another way.

Why is it Called the Seiko Captain Willard?

As mentioned, the original name of the Seiko Captain Willard is the Seiko 6105, which is simply just its reference number. The Seiko Captain Willard gained both its popularity and its nickname from a blockbuster film called Apocalypse Now, which came out in 1979. This movie featured a soldier named Captain Willard, played by Martin Sheen, who took part in the Vietnam War. Throughout the film, Captain Willard totes the Seiko 6105, which of course caught the interest of many watch enthusiasts. Apocalypse Now was a defining moment in the history of the Seiko 6105, and since then, people have referred to it as the Seiko Captain Willard.

A Closer Look at the Seiko Captain Willard

Now that we know the origin story of the Seiko Captain Willard, let us take a closer look at its impressive design and technical specifications. 


The Seiko Captain Willard 6105 is presented in a 44mm stainless steel case that boasts a cushion-shaped, asymmetrical structure. This gives it a large, chunky, and brazen look that is bound to catch the eyes of everyone. Despite its size, the Seiko Captain Willard is actually known to be quite easy to wear, thanks to the ergonomic build of its case, which molds itself quite comfortably to the shape of the wrist.

Aside from that, this watch also boasts unmatched durability, befitting its robust exterior, as it showcases a superb resistance to scratches, shocks, and impacts. Lastly, protecting this watch’s face from any external damage is Seiko’s trademark Hardlex crystal, which possesses anti-reflective properties that promise the wearer a clear and highly legible view of the dial.


Moving on to the bracelet, the Seiko Captain Willard 6105 comes with a striking rubber strap in black that perfectly complements its daring exterior. This black rubber strap shows off a bold and intricate waffle pattern, giving the watch a sportier, more outdoorsy aesthetic. Since the Seiko Captain Willard is a vintage timepiece, this unique band is actually now considered quite rare and valuable, so count yourself lucky if you manage to come across one of these.

Dial and Bezel

The dial of the Seiko Captain Willard 6105 also showcases a dauntless, rugged design that goes well with its case and bracelet. Like most divers out there, this model has a rather straightforward face that optimizes legibility. It comprises large hour indices in the shapes of rectangles and squares and silver-tone blunt hands, all of which are coated in lume for excellent visibility even in the dark. And while the Seiko 6105 does not come with any overly fancy complications, it does include a standard date window at 3 o’clock, outlined in silver, which adds to the watch’s functionality.

On top of that, the Seiko Captain Willard also comes with a unidirectional rotating bezel that is fitted with a black ceramic insert. This bezel bears luminous elements and clean, legible white indicators for a handy elapsed time scale, making the Seiko 6105 the ideal diving watch.


In order to match the robustness of its exterior, the brand made sure to equip the Seiko Captain Willard 6105 with an equally impressive interior. The Seiko Captain Willard is powered by an in-house Caliber 6105B. This well-crafted automatic movement consists of 17 jewels and has a frequency of 21,600 vibrations per hour (3Hz). It also possesses a decent power reserve of 32 hours, making it quite durable and reliable.


Produced only from 1968 to 1977, the Seiko Captain Willard definitely raised the stakes for future diving watches. It was able to acquire such a unique and highly-regarded reputation because it was built on three main pillars: pop culture, history, and excellent craftsmanship. To this day, the Seiko Captain Willard continues to be known as one of the best vintage divers that one could only dream of adding to their collection.

Price Range 

According to old Seiko catalogs, the original retail price of the Seiko Captain Willard was around $95 USD. Of course, since it has been out of production for more than 40 years, this watch has become considerably more valuable today. At present, the resale cost of vintage Seiko Captain Willard watches on the secondhand market is set at around $1,000 USD to $2,000 USD, depending on the seller and the condition of the piece.

First up, we have the Seiko Prospex Captain Willard Ref. SPB151J1, which is an exceptionally robust, professional-looking watch. Compared to the original Seiko 6501, this modern variant looks a lot more polished because of its sleek all-stainless-steel look. This is a great choice for those who want a more subdued, versatile version of the ever-so-famous Seiko Captain Willard.

This watch comes in a 42.7mm cushion-shaped case and bracelet, both made out of polished stainless steel. This is sharply contrasted against a rotating bezel with a jet-black elapsed time scale insert. This bezel has jagged, teeth-like edges, which ensure that wearers can grip and turn it easily.

The dial also comes in a striking matte black hue, complementing the bezel. This watch face is quite similar to that of the original Seiko 6501; it has the same luminous hour indices in square and rectangle shapes, blunt hands, and a date complication. However, this dial also differs in having slightly thicker hands and doing away with the silver outline around the date display.

Powering this Seiko Prospex watch is an automatic 6R35 Caliber. As a modern in-house Seiko movement, this caliber has an outstanding 70-hour power supply, which is a massive improvement from the original Seiko Captain Willard’s 32-hour power reserve. It also possesses a solid 200-metre depth rating, which is quite standard for a good dive watch.

Priced at $1,079 USD, this is a fail-safe option for all Seiko Captain Willard enthusiasts.

SBDC111 differs in having a different colorway and case finish, which gives it a more casual aesthetic and vibe.

The Seiko Captain Willard Ref. SBDC111 is housed in a 42.7mm stainless steel case and bracelet, both of which show off fine, satin-brushed finishes.

With its especially unique history, this is a timekeeper that should be on every Seiko patron’s rob list.
  2. Film Buffs. As we mentioned, the Seiko Captain Willard has strong ties to blockbuster film Apocalypse Now and that makes it a fantastic piece of merchandise for fans of that movie. Film buffs who love owning unique and exclusive merch will surely salivate at the chance to get their hands on the watch worn by Martin Sheen’s Captain Willard.
  3. Diving Professionals. Of course, even those who do not care about the Seiko Captain Willard’s heritage will also surely enjoy this watch.
