CONDITION
Seiko have had a number of horological milestones, with the most important being the first commercially available quartz wristwatch in 1969. But they didn’t sit back, their R&D department continued to develop numerous other firsts, with the 0634-5001 being the first LCD chronograph watch. Launched in 1975, this is typically over engineered like many early technology examples. It wasn’t a cheap watch mind – at ¥55,000 it was nearly three times the price of an automatic chronograph. The case and bracelet are all stainless steel. The pushers for the chronograph are on the front, not side of the case. You access the chronograph function by pressing the crown inwards, then the right hand button starts it and the left hand button stops and resets the feature. Condition is quite good all over, and the light still works (although these were never very bright!). We will install a brand new battery before sending the watch out to the new owner. The bracelet is the original XAB 990 model and quite long. Our sister website, SpareLinks.com, may have extra links if required. The bracelet has been cleaned in our ultrasonic bath.
This watch will be supplied with our branded presentation box and our Certificate of Authenticity.
