Seiko Divers Watch

Seiko Divers Watch

Why We Love It

As a diver's tool, the 6105 is a worthy instrument in all regards. 

Developed by Seiko in the late 1960s, the large asymmetrical watch boasted 150 meters of water resistance, a bi-directional bezel for dive timing and large swaths of luminescent material for high visibility underwater.  Used extensively in the field by soldiers and frogmen, the 6105 developed a reputation as a no-nonsense timepiece for professional use, a reputation that has lasted through to this day and undoubtedly inspired countless diving watches in the subsequent decades. Fans of Apocalypse Now will recognize the 6105 on the wrist of Martin Sheen's character Capt. Willard..

The 6105 is an absolute must-have in any dive watch enthusiast, but as with all Seikos of the 70s, originality is key, and the vast majority of those on the market are sadly modified or refinished. This particular example is a survivor - featuring an untouched dial and handset, clean case,  correct locking crown, and even retains its intact luminous pip.

Whether you "love the smell of napalm in the morning" or just want a damned dependable dive watch, the 6105 is what you need.   

The Story

Seiko is a brand that you either know and love... or don't. Walk into any department store and you'll no doubt be confronted with a case full of them, with names like Astron, Coutura, Kinetic, Solar. They're all modestly-priced, perhaps even suspiciously so, because anything that inexpensive couldn't actually be good quality, could it?

That's where you'd be mistaken. From the foundation of its clock-manufacturing arm in 1892, Seiko is one of the only true manufactures out there, rivaling even Rolex in terms of vertical integration. They've manufactured everything from their movements to their cases, right down to the crystals that power their quartz watches. It's that almost total vertical integration that has allowed them to offer their products at all price points, from the department store models all the way up to the high-end Credor timepieces with hand-painted enamel dials and hand-finished movements. Their vintage pieces have certainly earned the respect and admiration of those in the know. 

Their dive watches exemplify their mastery of anything they undertake. Seiko released its first dive watch in 1965, the Ref. 6217, which was soon eclipsed by what would come after: the Ref. 6105. Developed by Seiko in the late 1960s, the ref. 6105 boasted 150 meters of water resistance, a bi-directional bezel for dive timing and large swaths of luminescent material for high visibility underwater. 

The ref. 6105 was released in two different case styles: the 8000/8009 with its svelte cushion case and the asymmetrical behemoth, the 8100/8119. Like Panerai, the 6105 also has a military heritage: during the Vietnam War, U.S. troops purchased the cushion-cased variety from Post Exchanges. They brought them back stateside, starting a trend for over-sized tool watches which has persisted to this day.
