I have a very good condition flawlessly running "Baby Apocalypse" women's/boys diver from the 70s. The watch looks and runs great. The service history is unknown to me, but the Hi-Beat movement (28800 bph, 17 jewels) keeps excellent time and all functions work perfectly. The bezel turns freely with clicks in both directions. There are minor hairlines on the case and bezel which would be expected with very light use over its long life. There are also faint hairlines on the Hardlex crystal which do not affect legibility at all and did not photograph. Hands and dial are in very good condition. The original strap is in excellent condition. I cannot confirm that this was the strap the watch originally came with but it is the proper Seiko strap for this model. Although it is listed as a women's/boys model, I wore it on a Velcro strap on my 6.25" wrists and think it looks great (I have another one of these which I am keeping). The watch is small, but chunky and has much greater wrist presence than its small size would indicate (32mm bezel diameter, 36mm case (2:00 to 8:00) and 38mm lug-to-lug, 12.5mm thick). $525 shipped CONUS. Not looking for trades.
