Vintage Zodiac Astrographic SST mystery dial on OEM Zodiac bracelet. In perfect working order and keeping excellent time, though the service history is unknown. The bracelet will currently fit a 7 inch wrist, but can be widened or tightened with the micro adjustment on the clasp. I don't have a timegrapher to test it with, but I wore it for 2 days and it had no noticable positive or negative deviation. The silver dial has a sort of scalloped pattern in it. $450 shipped CONUS, PayPal only. Please message me with any questions. Thanks for looking!
