An early Seiko chronograph, which is one of the best 1980’s birth year watches available under four figures. Model reference 7A28-7049.
HOW DO WE DATE THIS WATCH?
From the serial number on the case back we can accurately date this watch to being made in December 1982.
The 7A28 15 jewel chronograph was the worlds first analogue chronograph with a quartz movement. The feat is acknowledged on Seiko’s own Milestone Watch website, but they date the introduction at 1983. So this is a very early production watch. The 7A28 went on to power watches used in Cartier watches, and different Seiko models feature in films such as Aliens, and was even worn by James Bond in A View to a Kill. The movement contains no plastic parts, hence so many have survived today.
In total there were 42 different variations, ranging from designs by Giorgetto Giugiaro to military versions for the RAF and South African Air Force. The 7A28-7049 was a US market only model, very similar to the 7040 version but with the Sports 100 text on the dial.
This example is still on the original bracelet, which is becoming more unusual and is nice to see. The bracelet has been cleaned in our ultrasonic bath. All functions are working correctly, without the sticky pushers that sometimes affects these. The unidirectional bezel has a strong click still, and the glass is good with just a couple of minor scratches. The case and bracelet are not polished, so will show minor scuff marks but no significant damage. The box is very good. These 7A28-7049 watches seem to be rising in value every month currently, and finding very good ones like this is becoming harder.
This watch will be supplied with the original presentation box and our Certificate of Authenticity.
