This is a Certina DS-3 !!!! Very nice homage !!!!
The DS-3 Super PH1000m was identical to the original DS-2 Super PH1000m, except it was a DS-3 rather than a DS-2 (even had the same ref. no.). The DS-3 reissue was a 1,888-piece LE. Finding any of the foregoing is a real challenge ... at least for a reasonable price. ;-)DS-3 Re-issue
