Modded 1987 SEIKO Diver 6309-7290 PADI
REFURBISHED VINTAGE SEIKO DIVER "6309-729A"
MODIFIED WITH PADI BLUE DIAL
NEW CROWN GASKET, BEZEL GASKET, CRYSTAL GASKET AND CASEBACK GASKET FITTED DURING RENOVATION
Absolutely superb example of this iconic divers watch with the caliber 6309 movement which has 17 jewels and runs at 21,600 bph. It's a non-hacking movement like most traditional Seiko calibers and has a quickset day and date calendar mechanism. The 6309 line of divers replaced the 6105 in 1976 and ran until 1988, when it was replaced by the 7002 line of divers. The 6309’s are largely an economizing and further modularization of the 6105 movement, which allowed for greater robustness, longevity and ease of maintenance. The 6309’s (especially the second generation of them) introduced many design changes to Seiko divers that are with us to this day. The 6309 divers come in two case variations: an earlier “cushion-cased” variant produced from 1976 to 1988 and a later “slimed-down case” variant produced from 1982 to 1988. As you can see production of the first generation continued after the second generation was introduced, and overlapped the second generation models, though in reduced number. The second generation of 6309’s abandoned the cushion style case in favour of a revised round “slimed-down” case-style, which continues to be used almost unchanged by Seiko’s basic line of divers to this day. Seiko's third model of diver's watches (6306/6309) have proven their worth. For over 3 decades they have withstood the test of time. One can say with conviction that a 30-year-old of this model when overhauled, cleaned, oiled and regulated will live for decades again. They are indeed the "workhorse" movements as described by their users/collectors around the world. This is a particularly good example of the later design from the 6309-729A second generation. This watch has been lovingly restored by one of the most respected Seiko watch restorers who has fitted a new PADI dial. It is looking stunning on a new stainless steel jubilee aftermarket bracelet - a true iconic classic - they don't come much better than this. A truly stunning watch collectors heritage watch which from the serial number we can see was born in November 1987. Perfect for diving, swimming or just looking cool.
