The 1995 Seiko Gen 2 (2nd Generation) Royal Air Force flight crew issued military analog chronograph was issued to Her Majesty’s armed forces from November 1990, following the issue of the Gen 1 quartz chronograph.
The caseback is inscribed with the "broad arrow" and NATO Stock Number (NSN) 6645-99 7683056 used for military-issued equipment:
6645 = Time Measuring Instruments
99 = NATO Country code United Kingdom
768-3056 = individual part number
In contrast to the commercial versions, the issued version has a 38mm case with a matte, bead-blasted finish, fixed strap bars and a "circle P” dial, indicating radioactive Promethium lume.
The register at "12" is the 30 minute counter, the register at "6" is the continuous seconds and the register at "9" indicates the current hour on a 24-hour scale.
The 7T27 (Gen 2) movement takes an SR927SW (395) 9.5 x 2.6mm battery.
