Up for sale is a superb example of the Squale 20 ATMOS Classic (Ref. Y1545). This is the discontinued aluminum bezel version that many collectors prefer for its slimmer profile and classic "Sub" aesthetic. This watch is in excellent condition and comes as a complete full kit. Most importantly, the movement is performing at a chronometer-grade level (see timegrapher photos). It is running dead-on at 0s/d with a strong amplitude, which is rare for a pre-owned piece.
