An interesting dial for modest money, this Seiko dial flips from blue to black.  Model reference 2620-5140.

HOW DO WE DATE THIS WATCH?

From the serial number on the case back we can accurately date this watch to being made in August 1988.  Movement 2620 was launched in 1979 and ran until about 1990, so this watch can not be from any other year than 1988.

CONDITION

It’s the dial.  That is what we look at most as collectors and wearers of old watches, and while there might be technical aspects of a watch we all like we wouldn’t buy a technically great watch if it had an ugly (to us) dial.  So inside this watch is Seiko calibre 2620 quartz movement, a simple set and forget that is working well.  But the part we like most is especially good on this watch.  The dial looks black in most lights, but then the angle changes a royal blue dial emerges.  The video will show this effect the best.  The bracelet, number XAM240L, looks integrated but it isn’t, so could be swapped for a leather strap if preferred.  The bracelet is full length and can be adjusted without the need for special tools.  We will install a brand new battery before sending the watch out to the new owner.  The bracelet has been cleaned in our ultrasonic bath.

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