Seamaster Diver 300M Aluminium Bezel

The Older Bezel, and Some Prefer It.

An aluminium bezel insert rather than ceramic, which reads slightly warmer and ages rather than staying perfect. Black dial, steel case and bracelet, 300 metres.

A helium escape valve sits at 10 o'clock, fitted for saturation divers coming back up through decompression.
