Object description

Design and Dial Construction

The timepiece features a multi-layered dial designed for the calculation of latitude and longitude via the hour angle. The dial layout includes an outer white enamel ring displaying Roman numerals and blue Arabic numerals representing degrees. A central rotating disc, finished in light gray, includes a red graduated ring and is manipulated using the crown.

The watch includes a rotating silver bezel marked with black graduations intended for navigation. The time is indicated by blue-toned Breguet-style hands. The watch is equipped with an onion-style crown for winding and a pusher located at the 4 o'clock position, which is utilized for setting the time.

Movement and Mechanical Specifications

The watch is powered by a manual winding movement identified as Caliber 18.69N, which features 15 jewels. This caliber was first developed in 1908 and was frequently used in the pocket watches produced by the manufacturer. It operates at a frequency of 18,000 A/h and provides an approximate power reserve of 36 hours.

The 18.69N caliber was employed for the first three generations of the Hour-angle series. This specific movement was produced with either nickel or gilt finishes, reflecting the manufacturer's production standards for aviation timepieces during this era.
