Period
circa 1900
This Haas Neveux & Cie pocket watch, serial number 20544, is a platinum-cased timekeeper manufactured circa 1900. The watch is defined by its digital display system, which indicates hours, minutes, days of the week, dates, and months through a series of apertures on the dial.
The mechanism is a keyless, slim jump-hour movement, measuring 18''' and featuring 18 jewels, a straight-line lever escapement, and a cut bimetallic compensation balance with a blued steel flat balance spring. The movement is finished with fausses côtes decoration. The case is a three-piece, "bassine"-style construction in polished platinum. The dial is silver and matted, with the time and calendar information arranged in distinct sections.
The piece is accompanied by an original fitted box.

Design
- Visible features
- • Apertures for digital day, date, and month displays are positioned in the upper portion of the dial. • A semi-circular arc aperture displays digital minutes. • The jump-hour indicator is located in an aperture at the bottom of the dial. • The bow is designed with an angular, geometric shape.
- Case and Dial Configuration
- The watch is housed in a three-piece, "bassine"-shaped platinum case, which has been polished. The back of the case is monogrammed. The overall thickness of the piece is 7.5 mm, reflecting a slim profile for a complex complication. The dial is composed of a matted silver surface containing several discrete apertures for the digital display. The days of the week, dates, and months are presented through individual windows at the top. Below this, a semi-circular aperture indicates the minutes. The current hour is shown through a separate jump-hour aperture located at the lower portion of the dial.
- Provenance and Historical Context
- This specific timepiece incorporates a digital perpetual calendar system, which the source states was introduced by Haas Neveux to a design by Robert Cart. The watch is distinguished by its combined display of calendar information and digital time. Haas Neveux watches manufactured in platinum are noted as being rare. According to the provided information, the auction house has previously sold two other examples of this model, both within a small numeric range of the serial number identified for this item.
- Movement and Technical Specifications
- The watch is powered by an 18-ligne movement featuring 18 jewels. It utilizes a straight-line lever escapement and a cut bimetallic compensation balance, which is paired with a blued steel flat balance spring. The movement bridges and plates feature a rhodium-plated finish with "fausses côtes" decoration. The signature appears on both the dial and the case, with matching numbers on both the movement and the case.
