Seiko 6105-8110 “Captain Willard” – 100% Original Vintage Diver An icon of Seiko’s golden era of tool watches, the 6105-8110 — famously known as the “Captain Willard” — stands among the most collectible vintage divers ever made. This example is a true survivor: 100% original, never polished, and presented in honest vintage condition. The watch features its original dial, hands, bezel, case, crown, and movement, all untouched and consistent with the 6105’s production period. No aftermarket parts have been fitted — only the rubber strap is a modern replacement in the classic style of Seiko’s 1970s “tire tread” straps. The Seiko Caliber 6105B automatic movement powers the watch, offering improved reliability and the hacking function (stop-seconds) compared to the earlier 6105A. The movement runs well; however, as with all vintage mechanical watches, a personal overhaul is recommended for perfect accuracy and long-term reliability. ⸻ Key Features • Brand: Seiko • Model: 6105-8110 “Captain Willard” • Movement: Seiko Cal. 6105B, 17 jewels, automatic with hacking function • Case Size: 44 mm (without crown) • Case Material: Stainless steel (original, unpolished) • Crystal: Original 60's Seiko Hardlex glass has no scratch and in perfect condition • Dial: Original matte black with luminous markers • Bezel: Original bidirectional, shows period-correct wear • Crown: Original “Lock” crown, 4 o’clock position • Strap: New old stock vintage rubber strap • Condition: Vintage, unpolished; honest signs of wear consistent with age • Function: Working; keeps time well; overhaul recommended for accuracy ⸻ Collector’s Note This watch is for true enthusiasts who value authenticity and originality over restoration.

Despite being a late entrant to the dive-watch scene, the 6105 quickly earned a reputation for unmatched toughness, reliability, and value for money. It became known as an “unlikely hero” — a robust, affordable, mass-produced diver that proved itself in some of the harshest environments on Earth. ⸻ The Vietnam War Connection The 6105 gained its iconic status during the Vietnam War, when countless U.S. soldiers purchased it from PX (Post Exchange) shops, which offered goods at steep discounts for military personnel. Unlike cheaply made issued watches such as the MIL-W-46374, which were disposable and often plastic, the Seiko 6105 was a serious, professional-grade tool. It was favored by servicemen for its: • Durability under jungle heat, humidity, and monsoons • Ease of maintenance • Affordability and availability in Southeast Asia Its association with Captain Willard, the main character in Francis Ford Coppola’s “Apocalypse Now”, led to the nickname “Captain Willard Seiko.” But, as the video notes, the 6105’s real legacy comes not from Hollywood, but from the soldiers and adventurers who relied on it in real-life extreme conditions. ⸻ Famous Wearers & Extreme Missions • Naomi Uemura, the legendary Japanese explorer, wore a Seiko 6105 during his solo expeditions, including the incredible 18-month crossing from Greenland to Alaska by dog sled, and climbs of Mount Everest and other peaks on six continents. • Dr. David Williams, a Canadian astronaut, used the 6105 in space and during underwater missions in NASA’s Aquarius habitat. He described it as a meaningful reminder of his parents, who gifted him the watch. These real-world achievements reinforced the 6105’s reputation as a dependable companion in the most extreme environments — from jungles to space. ⸻ Legacy & Collectibility Today, the Seiko 6105 is considered one of the most collectible vintage Seikos, beloved by both military historians and dive-watch enthusiasts. While prices are rising, vintage examples can still be found — though collectors should watch for crown wear or moisture damage on the dial and hands. Seiko’s modern reissues (like the SPB151/SPB153) faithfully preserve the 6105’s rugged character while upgrading technical performance. ⸻ #supercoolwatches
