When Timing Is Everything.

The Dwellingham Blue Note Deepsea Diver is a 43mm high-beat automatic dive watch built around precision, wrist presence, and the musical legacy of Herschel Dwellingham Sr.

Inspired by New York City's Blue Note jazz tradition and the discipline required underwater, this timepiece connects two worlds where timing matters: the stage and the deep. On stage, timing creates rhythm. Underwater, timing is survival.

Story

The Blue Note Deepsea Diver honors the legacy of Herschel Dwellingham Sr., a musician, film composer, television composer, Berklee School of Music graduate, and creator of notable charting music dating back to 1968.

Each Dwellingham timepiece is hand-finished and polished in the USA. Before sale, each watch is inspected, smoothed, and polished for improved comfort and a refined feel on the wrist.
