The 1A 40 has always been core to the Sheffield story. It was the first true update of my original Sheffield Diver, now refined with a steel coin-edge bezel that is even truer to the original.

More than 50 years after I received my first Sheffield in 1970, this watch represents a dream turned reality. Incredible specifications and build quality come together in a distinctive design that still stands out today while respecting the intent of the original.
