Seiko 6105 Captain Willard – A Classic Vintage Diver

If you’re a Seiko fanatic, we are sure you must be fascinated with many of their iconic watches, and in today’s, we will be presenting you with a detailed review of the iconic Seiko 6105 apocalypse and now known as Captain Willard.

But before we give you a hands-on experience of the famous Seiko 6105, let’s give you some brief history about the Seiko brand.

About Seiko

Since the company’s sojourn into the watch industry many years ago, they have remained pretty consistent.

No wonder they are a force to reckon with even today.

Thanks to their collections of really incredible timepieces, Seiko has solidified their place among the best, not just in Japan but worldwide.

Started from a small shop in Ginza, Tokyo, in early 1881, the company has grown into a global brand, with many iconic watches to its name, which showcase Japanese craftsmanship.

Although the company started off repairing and selling watches, things took a turn for the better in 1892 when the company opened another factory in Seikosha.

It was in Seikosha that the company began producing iconic watches.

This coincided with the launch of the Timekeeper- the first-ever pocket watch to grace the industry.

While the Timekeeper enjoyed overwhelming success, the company followed up with the release of their first-ever watch to carry the Seiko brand name in 1923.

Since then, the company has continued to release exquisite watches, and even till now, they are a force to reckon with in the watch industry.

Seiko 6105- the unveiling

Seiko has indeed written its name in the sands of time when it comes to diving watches.

That said, none of their dive watches is as iconic as the brilliant Seiko 6105.

Besides being breathtaking and holding its place among other famous dive watches of the 1970s, this superb timepiece leaves nothing to be imagined as it has some of the most exciting specs we have seen among dive watches.

As with other 3rd generation divers from the Seiko brand, this wristwatch follows in the footsteps of other legendary Seiko watches like the 6217, famously called the 62mas, and the much slimmer 6105-8000/9.

Even though these timepieces were somewhat similar, the last digit in their reference number showed what market they were originally sold.

Made from 1970 to 1977, the Seiko 6105 dive watch came in two variations.

The first models featured a “water 150m proof” inscription labeled on the dial and waterproof, clearly visible on the back.

However, they later switched things up as they changed the inscription to “water 150m resist” and “water-resistant” on the back.

Today, the “proof models” are super rare and far more valuable than the “resist” variants.

Seiko 6105 Case

While many Seiko watches have that signature design that many Seiko fanatics have become accustomed to, the Seiko 6105 has a brilliant design and top-of-the-line asymmetric casing that makes it a lot different from other Seiko dive watches we have come across.

With a 44mm diameter, you’ll agree that this dive watch is on the big side.

That said, we love the fact that its cushioned cased shape along with 47mm length allows this watch to sit comfortably on any wrist.

Besides its mind-blowing design, the Seiko 6105 boasts of an impeccable 3 part construction which includes a specially designed mid-case, a closed-back case, and a bi-directional 60 click bezel.

The beautiful thing about the mid-case is that it not only gives the watch a brilliant look and feel but is also beautifully crafted to protect the oversized crown fitted at the 4 o’clock point.

This not only adds to its aesthetics but also gives the timepiece its unique identity.

Seiko 6105 dial

If you know anything about dive watches, you’ll know that they feature a highly legible dial, and with the Seiko 6105, we found it to be pretty consistent with this tenet.

As per the dial, the Seiko 6105 features a dial with the signature matt black color.

Plus, we love that things have been nicely laid out.

With no unnecessary clutter, the Seiko 6105 dial has very legible and minimal text in the form of the company’s signature logo at 12 o’clock.

This is followed by the word “Automatic” sitting underneath the logo.

We also have a water-resistant text, nicely placed above 6 o’clock.

The hour hands of this watch showcase a blend of squares and rectangles at 6 and 9, while the double markers at 12 give a rich depth to the dial.

Keep in mind that the hour markers all carry the signature luminous material, making the dial glow even in the dark.

Seiko 6150 Movement

When it comes to movement, the Seiko 6105 runs on the popular Seiko caliber 6105B movement.

This famous 17 jewel self-winding movement is best known for its low beat movement, especially considering that it functions at a frequency of 21600 BPH.

Although this watch has a hackable movement, it doesn’t support hand winding, which is the only complaint we have about the movement.

Seiko 6105 Bracelets

Unlike many popular Seiko dive watches with a great stainless steel bracelet, this one comes with a rubber strap.

Even though the rubber strap is super comfortable and will guarantee a pleasant wearing experience, you can always change it to a stainless steel bracelet if that works best for you.
