In this modern iteration the case measures 40mm across, whilst holding a self-winding movement with chronograph in the form of caliber H-31. Ref. H38416711 has a silver dial with black counters and a black tachymeter scale. Introduced in 2018, it is 2mm smaller in diameter than the limited edition H38716731 that preceded it.


Hamilton caliber H-31 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.
