Excellent, like new condition Squale 1545 20 Atmos Classic (Y1545).  Swiss movement, works correctly and runs  accurate.  No marks that I can find, but possible use signs on clasp may be visible in the right lighting. Tested with timegrapher at under 10 seconds per day fast, with strong beat.  It is sized for about 7" wrist with the removed links and screws all present.  No complaints, but decided on different model.
