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 1989.

CONDITION

Seiko were the first Japanese brand to make a divers watch, and the first watch maker worldwide to launch a quartz watch, so a Seiko divers watch with a Quartz movement makes perfect sense.  SQ stands for Seiko Quartz, and the Sports 150 is because this sports watch was water resistant to 150m.  The dial is very good, and the white on black calendar wheels work really well.  Both day and date can be quickset, and the day wheel is in English and French.  The crown still screws down positively.  We will install a brand new battery before sending the watch out to the new owner.  The case has a few marks but is unpolished, and the bezel clicks nicely in both directions.  The glass is perfect, but the hands do show some loss to the luminous material.  The bracelet is nearly full length and our sister website, SpareLinks.com, may have extra links if required.  These folded link bracelets don’t always survive, and this one does show signs of stretch, but it is a real bonus to still have the bracelet with the watch.  The clasp is crudely engraved with some initials, as well as the correct SQ stamp.  The bracelet has been cleaned in our ultrasonic bath.

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