Up for sale is a rare Seiko Instruments Inc. (SII) branded automatic field watch that was not sold to the general public. These were likely built for internal use or specific OEM contracts under Seiko’s instrumentation division—not standard retail Seikos. This model runs on the Y675 automatic movement, a mechanical caliber closely related to the Seiko 7S26 family. It features a silver dial with a clean military-style layout, bold black numerals, a date window at 3, and the distinctive blue dot + "SII" branding under 12. The caseback is unbranded, consistent with OEM or non-retail Seiko variants. It’s fitted on an aftermarket black leather strap and wears comfortably thanks to its compact size and lightweight profile.
