1977's Vintage Seiko Divers 150m Black Pepsi Bezel Dial 6309-7290 Automatic Watch

Case No. 703965 - October of 1977

The 6309 divers replaced the 6105 as the standard models of 150m divers. The 6309s were marketed outside of Japan while a version using the 6306 movement was sold only in Japan (but for a relatively short 5 years).

The cal. 6309 movement is a successor of the 6105. It has 17J and runs at 21,600 bph. It's non-hacking and has a quickset day/date calendar mechanism.

Like the 6105, there are 2 series of 6309 divers. The earlier versions -- 6309-7040 and 6309-7049 -- are housed in big cushion cases and have round markers. The later versions -- 6309-7290 and 6309-729A/729B -- have slimmed-down cases and rectangular markers (which make them very similar to the current SKX007/173 models). While the earlier 6105 divers used the "turn and lock" crowns, the 6309 crowns are all screw-down. The 6309 divers seem to all have bi-directional non-locking bezels.
