The first Tudor Submariner watch with self-winding movement is created in 1956.
The Oyster case by Rolex has a diameter of 39mm, the bidirectional rotatable bezel features a metal insert graduated for measuring the duration of immersions.
The dial with gilt print and minute track has indexes and hands treated with radium.
The writing “Rotor Self-Winding” reminds us that the watch winds itself by means of a rotor.
The depth rating, to which the watch is guaranteed waterproof, is indicated both in meters and in feet, thus “100/330”. The hands (Mercedes style hour hand and baton minute hand) are in brass.
The crystal is in hesalite and domed to distribute and better resist water pressure.
The screw-down winding crown has a diameter of 6mm.
The expanding rivet Oyster bracelet is later replaced with the one having fixed links.
