Here is a Squale Eagle Star Professional diver’s watch measuring 41mm. and housed in a (never polished) robust stainless steel screw-back case. The SWISS automatic movement was just serviced and is accurate. The blue dial, luminous and hands are all original. The perspex turning bezel is original with some (usual) wear to be found. The crown screws down. These are highly sought after vintage 1970’s professional dive watches-and what a dial!
