The Gen 2 is a practical but rugged military watch that can be worn daily, with the extra complications to boot.  Model reference 7T27-7A20.

HOW DO WE DATE THIS WATCH?

From the serial number on the case back, plus the issued date also engraved there, we know this watch was made in February 1993 and issued in the same year.

CONDITION

Gen 2 means this is the second generation of Seiko chronograph to be issued by the British Military.  The first generation is a favourite of ours, the 1983 Seiko 7A28-7120, and the Gen 2 moves the subdials, adds a date, and has the crown at 3.  The dial also has a P in a circle, and this shows the watch uses Promethium 147 for lume.  This material has a very short half life of just 2.62 years, so presents no potential danger to the health of the watchmaker any more, but does still have some glow (Tritium is 12.7 years, and radium 1,600 years for comparison!).  All functions including the quick set date date are working perfectly.  The case has light marks, and the case back has the classic ‘nylon rash’ from the type of straps used – military watches are usually specified with fixed bars so a one piece strap must be used.  This is because if one bar broke in action the watch wouldn’t fall off the wrist, whereas spring bars would mean the watch would be dropped and potentially lost.  We will install a brand new battery before sending the watch out to the new owner.  The nylon strap is new, and could be swapped for a different colour if preferred.

This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
