Object description

Case and Dial

The watch features a 38 mm stainless steel case equipped with a fixed tachymeter bezel. The exterior configuration follows the standard Speedmaster layout, incorporating a crown and two pump-style pushers on the right side of the case to operate the chronograph functions.

The matte black dial serves as the foundation for the chronograph and moonphase displays. It features luminous baton indices and a minute track calibrated to 1/5th of a second. The hands are also luminous, maintaining the design of the Professional series while accommodating the additional complexity of the calendar and moonphase apertures.

Movement and Functions

The timepiece is driven by the manually-wound calibre 866 movement. This movement enables the chronograph functions, which are managed via sub-dials located at the three, six, and nine o'clock positions, representing 30-minute, 12-hour, and constant seconds respectively.

Beyond the chronograph, the watch includes a moonphase complication. The integration of these astronomical and sporting complications characterizes the 'SpeedyMoon' variant of the Speedmaster line.
