Object description

Case and Dial Design

The Senator Chronometer is constructed as a three-body case crafted in 18K red gold. The design features a stepped inclined bezel and concave lugs, emphasizing a polished finish. A notable aesthetic detail is the winding crown, which is set with a black cabochon. The case utilizes sapphire crystals on both the front and the transparent exhibition back.

The dial exhibits a matte black and silver composition. It is marked with radial Roman numerals and an outer minute track. Functionality is integrated through a power-reserve sector positioned below the 12 o'clock marker, a guilloche subsidiary seconds dial, and distinct apertures for the panorama date and day/night indication. The time is displayed via red gold poire hands.

Movement and Chronometry

The watch is driven by the Caliber 58-01, a rhodium-plated movement finished with fausses cotes decoration. The architecture includes 58 jewels and a straight-line lever escapement. Accuracy is regulated by a swan-neck regulator acting on a monometallic balance with 18 screws, supported by a shock absorber and a self-compensating flat balance spring.

An integrated stop-seconds hack mechanism with a minute detent allows for precise time setting. The movement has undergone formal chronometer certification within Germany, confirming it met required standards for precision and rate through testing.
