Object description

Case and Aesthetic Construction

The timepiece is constructed with a three-body stainless steel case, measuring 35 mm in diameter and 11 mm in thickness. Its physical profile is defined by its flared, fluted lugs, which serve as a primary design element for this specific reference. The case surfaces are finished with a combination of polished and brushed textures.

The dial is rendered in a matte silver tone, providing a backdrop for applied pink gold baton indexes and corresponding Arabic numerals. The time and chronograph readings are indicated by pink gold baton hands. For measuring speed and distance, the outer edge of the dial incorporates tachometer and blue telemeter graduations. Two subsidiary dials, finished with a guilloché pattern, facilitate the registration of 30-minute intervals and continuous seconds.

  • “Three-body, polished and brushed, flared fluted lugs.”
  • “Matte silver, with applied pink gold baton indexes and Arabic numerals, subsidiary guilloché dials for the seconds and 30-minute registers, outer tachometer and blue telemeter graduations.”

Movement and Mechanical Specifications

The watch is driven by a rhodium-plated 13''' movement. The mechanical assembly comprises 17 jewels and employs a straight-line lever escapement. Regulation of the timekeeping is achieved via an index regulator, paired with a monometallic balance wheel and a self-compensating Breguet balance spring. This movement supports the watch's chronograph functions, operated by square buttons located on the case side.

The auction house notes that the watch is signed on the dial, the case, and the movement.
