Time Spec: Seiko 7A28 RAF Gen 1 Chronograph

A few months prior, we showed you the physically wound mechanical chronographs gave by the British military pilots in the 1970s.  Today, we’ll investigate what came next.

In the mid 1980s, the military powers of the UK went searching for another pilot chronograph to supplant the Valjoux 7733-fueled chronographs they had been giving for the past decade.  By this time, quartz innovation had progressed to a degree of value and moderateness that settled on it the conspicuous decision for the new watch.  The company chose to make the new watch was the Japanese company Seiko, denoting a takeoff from the Swiss, American, and English brands the Ministry of Defense had beforehand used.

It’s nothing unexpected that the MoD chose to search east for their new watch.  Seiko had been delivering astounding quartz watches for  a long time, and the watch they gave was an awesome illustration of everything a quartz chronograph could be.  The 7A28-7120, presently frequently called the Gen 1 (Seiko later provided a second era during the 1990s), was first given to British pilots in October 1984 and was not supplanted until November 1990.  During that run, the MoD purchased and gave an aggregate of 11,307 Gen 1 chronographs, making it one of the more various chronographs gave to military forces.

During the time they were providing these watches to the British military, Seiko was additionally creating a wide assortment of 7A28 chronographs for the non military personnel market.  However, a couple of contrasts exist between the Gen 1 and regular citizen 7A28 variants.  The Gen 1’s case is less complex than all commercially accessible 7A28 models; it has a matte, impacted completion, an incorporated, plain bezel, and fixed tie bars.  To comply with military rules, Seiko stepped a “circle P” on the dial, demonstrating that Promethium – a somewhat radioactive man-made component – was utilized to enlighten parts of the dial and hands.  On the caseback are stepped the NATO stock numbers, just as the watch’s singular issue number and year of issue.  The broadarrow image shows that the watch was property of the Crown and didn’t have a place with an individual warrior or sailor.

Like all Seiko 7A28 models, the Gen 1 has an all around planned, practical chronograph with the stopwatch pointers orchestrated proficiently around the dial.  The 3:00 o’clock register estimates 1/10ths of a second, while the huge focus hand ticks steady seconds.  The 9:00 o’clock register records chronograph minutes up to 30.  Time is shown with standard focus hour and moment hands and a persistent seconds hand in the base register.

The 7A28 development, formally presented by Seiko in 1983, is prominent for being the primary quartz simple chronograph, which means the stopwatch utilizes hands pushed by a battery-controlled quartz movement.  Prior to its presentation in the mid 1980s, all past chronographs had either been simple (with hands) controlled by a mechanical, spring-controlled development, or advanced (with a screen) fueled by a quartz movement.  The 7A28 made ready for the reasonable, solid, and snappy quartz simple chronographs we see available today.  The utilization of metal cog wheels all through the development made it hearty and effectively fixed, which means the watches can keep going quite a while if well maintained.  Collectors have observed, and a strong community exists for gathering and keeping up these watches and other 7A28 models.

The Gen 1 was initially given on an earthy colored nylon 1-piece lash with a pigskin cowhide cuff.  Very not many of these unique earthy colored groups actually exist, yet changes are accessible from Phoenix ties, the first provider of the lashes for the British military.  Most pilots decided to wear the Gen 1 on a dim 1-piece tie, and it’s difficult to contend with that exemplary combination.

The Gen 1 falls in the collectable milwatch value range, ordinarily selling somewhere in the range of $500 and $1000, contingent upon condition.  Keep an eye on eBay, the Seiko Citizen Watch Forum , and the Military Watch Resource for great vintage instances of this watch.
