There are many vintage Seiko divers popular with collectors, and the diver here – a Japanese Domestic Market-only 1997 Seiko 7N42-8260 (SBCA001) "Military" field watch here, with original Seiko 7N42 instructions manual – continues the Seiko reputation for building robust, stylish, and purpose-built divers for a wide-range of professional adventurers.
The 7N42 dial here is stark and utilitarian, with military-esque hour indices, features an exceptional, high-contrast, black Seiko-signed dial and hands that glow strongly in low light - all reminiscent of iconic USMIL-issued mechanical watches.
Military forces the world over have long took note of Seiko’s dive watch lines, with their reliable movements – during its heyday and even today, Seiko divers are popular with various armed forces for this same reason, despite the widely held (false) assumption that military personnel only wear military watches issued to them.
Seiko debuted its 7N42 line in the mid-1990s, after it perceived a disconnect between its offerings and younger consumers, in an attempt to wean the same customers off of digital quartz watches made by Seiko competitors.
This Seiko diver comes on a beige nylon strap, and with a second nylon strap, rugged travel case, springbar tool, and Seiko 7N35 instructions manual.
