Need a New Bezel for this watch terribly, Runs fantastic. Lug Width is 20mm. Case Height 45.5mm, Width Approx. 37mm. I have a Crystal on Back Order
Thanks OT- I'm batting 1000 today. Too much turkey. One tick as now published. If changed to Deep Sea Chrono, then three ticks.....
The Case design and Caseback outer markings of the subject are identical to a known 'DEEP SEA CHRONOGRAPH'

the inner marking almost identical, bar the case reference #.


"Super Compressor"

In reply to The Case design and Caseback by FifthAvenueRes…
If the watch does not bear the patents for the Compressor or Super Compressor technology, they are not "Super Compressors".
Maybe this ad helps with naming the watches. Ad from December 1971.
Chronograph, Deep Sea Chronograph and Calendar Chronograph.

Great find by Geoff.
