Seiko's 6105 model marked their second true diving watch featuring the distinctive cushion-shaped case. The uniquely asymmetric design of the case was engineered for durability, housing a recessed signed crown at the 4 o'clock position. This timepiece gained popularity among American servicemen during the Vietnam War and gained further fame when actor Martin Sheen, portraying "Captain Willard" in the 1979 film Apocalypse Now, sported it. In Japan, it's often referred to as the "Uemura," honoring the Japanese adventurer Naomi Uemura, who wore the 6105 during his 18-month dog sled journey across Greenland from Alaska.

The Seiko 6105-8110 stands apart from other watches, primarily due to its distinctively asymmetrical case design. Measuring 44mm in width, the watch commands a substantial presence on the wrist. Despite its size, the relatively compact 47mm length, combined with the cushion-shaped case, ensures comfortable wear without any awkward overhang, a common issue with larger cases. The case comprises three parts: a solid case back, a cleverly crafted mid-case, and a bidirectional 60-click bezel with an aluminum insert.

Its matte black dial is thoughtfully arranged, free from unnecessary clutter. The minimal text includes an applied Seiko logo at 12 o'clock, accompanied by "Automatic" below it, creating a balanced visual. Above the 6 o'clock position, the water resistance-related text provides further detail. The hour markers consist of a blend of applied squares and substantial rectangles at 6 and 9, with a dual marker at 12, adding depth to the dial and lending the watch a bold appearance.

This particular example is recognized as the "Resist" variant. Early models from 1970 displayed "Water 150m Proof" on the dial and "Waterproof" on the case back. However, at some point that year, Seiko modified the text to "Water 150m Resist" on the dial and "Water Resistant" on the case back, in compliance with updated ISO guidelines before the January 1972 deadline.

Condition-wise? We're incredibly excited to offer this unused and mind-blowing example: With no scratches observed, this Uemura still retains its original sticker on the case-back and comes with its original Tire Tread XGL-731 and its original box.

A fantastic example of Seiko’s iconic diver history, if you've been looking for the perfect example then this is it!
