My watch is from July, 1972, so either ring should work. If anyone sees one, or has one available, please let me know. Thanks.Kat, here is the part number you'll be looking for. If you'll notice the early style (69'- early 70') inner bezel uses the same part number as the later style (70' + up). You'll notice on the early bezel there is no notch and it has external teeth. The later bezel has a notch and no outer teeth.
On a side note: the later inner bezel can be used on an early model but the early model inner bezel won't work on a later model due to a different style dial spacer ring.
