This exceptionally rugged, ultra-lightweight field instrument is an authentic JDM artifact from September 2001, as definitively verified by the serial number 190862 stamped across the solid titanium screw-down caseback alongside the clear "MADE IN JAPAN" marking. Engineered for extreme resilience without wrist fatigue, this reference combines high-grade hypoallergenic solid titanium construction. It houses the dependable Seiko Caliber 7N43 quartz movement, a robust three-hand workhorse engine renowned for its set-and-forget electronic reliability and a dual-language English/Kanji day-date calendar mechanism.
The case architecture features a solid titanium chassis defined by brushed surfaces, ergonomic integrated crown guards protecting the screw-down crown at 3 o'clock, and sculpted lug shoulders. The dial presents a clean, high-legibility ivory-silver face appointed with bold black-accented applied baton indices, matching luminous sword hands, an outer minute track, and a framed quickset Kanji day-date window at 3 o'clock. Fitted to a durable black leather strap, this 200-meter rated all-titanium tool watch delivers exceptional wrist presence and go-anywhere functionality
