The Hamilton H-31 is based on the Valjoux 7753. The H-21 is similar though based on the 7750. These movements most notable change compared to the standard version is the 60 hour power reserve.

The following elements have been modified:

- The entire kinematic chain has been refined, from the barrel to the escapement
- The escapement regulator has been suppressed, facilitating optimal reliability and precision
- The main spring has been improved to increase a typical power reserve of 60 hours.
- The mono-block rotor is distinctively skeletonized with an “H” shape and aviation-inspired cut-outs, a signature of individualization.

The ultra-modern maritime masterpiece takes its shape from the iconic Hamilton Piping Rock piece from that year, even chosen by the New York Yankees baseball team as their official timekeeper. It visibly rides the tide of time using today’s technology and materials to pay tribute to a watch that has fascinated wearers in evolving executions for over six decades and is still a collectors’ favorite. With its round dial held in place by a tonneau case, comprising intriguing open corners to show tiny glimpses of the wrist, this eye-catching watch knows exactly how to maintain its established talking point status.
