Rare Sandoz vintage diver from the 60s with Super Compressor case and automatic movement. The huge 40mm case is in unpolished condition and has light lines, use and tools marks but no dents, rust or damages, both original and signed crowns. 
The original silver untouched dial is in very good condition and the tritium has a nice warm patina, as well the inner rotating bezel that works and rotate properly. Plexiglass crystal has light scratches.
The Automatic movement has a fair good timekeeping and amplitude but no service history or guarantee. 
New suede strap.
