It uses \u003cstrong\u003e7A28, launched in 1983 \u003c\/strong\u003e- it's the world’s \u003cstrong\u003efirst analogue quartz chronograph\u003c\/strong\u003e movement, and it was the first Seiko chronograph \u003cstrong\u003eissued by the RAF.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe dial has three sub-registers: running seconds at 6 o’clock, a 30-minute counter at 9, and a 1\/10-second display at 3. The chronograph is started, stopped, and reset with separate pushers, and the split-seconds control (pusher at 10 o'clock) makes it more complicated and technical than other Chronographs of the era. \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRAF issue history\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eIt was said that the RAF adopted the \u003cstrong\u003e7A28-7120 (Gen 1)\u003c\/strong\u003e in October 1984, and issue continued until November 1990, when it was replaced by the \u003cstrong\u003e7T27-7A20 (Gen 2)\u003c\/strong\u003e. Around 11,300 pieces of the Gen 1 were supplied in total, making it one of the rarest and best known British military quartz chronographs. \u003c\/p\u003e\n\u003cp\u003eThe watch was ordered to replace earlier mechanical chronographs for reliability, accuracy, and lower maintenance. The RAF version used fixed spring bars, a matte case finish, and a black dial with \u003cstrong\u003ePromethium lume, marked by the circled “P” under the Seiko logo. \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e7A28 Movement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe 7A28 family is much broader than the RAF model.
