Haas Neveux Jumping 24-Hour Dress Watch

Partially verified

This Haas Neveux & Cie dress watch, serial number 70306, is a keyless pocket watch made circa 1920. Housed in a three-body 18K white gold 'bassine pincee' case, the watch features an unusual jumping 24-hour mechanism. The matte silver dial uses apertures to display the hours, cycling from 0-11 in the morning to 12-23 after midday, and incorporates a subsidiary seconds register. The movement is a rhodium-plated 17-ligne caliber decorated with fausses côtes, featuring 18 jewels, a straight line lever escapement, and a cut bimetallic compensation balance with a flat balance spring. The movement bears the Geneva quality mark. The watch is signed on the dial and case, with corresponding numbers on both. It includes blued steel Breguet hands and a triangular bow,

Object description

Case and Dial Design

The watch is presented in a three-body 18K white gold case described by the source as "bassine pincee" and polished. A distinctive feature of the exterior is the triangular bow. The dial is finished in matte silver and diverges from conventional layouts by utilizing apertures to present the time.

The jumping mechanism is engineered to display the hours in a 24-hour format. During the morning hours, the dial windows show numerals 0 through 11. Upon reaching noon, the numerals jump to display 12 through 23. A separate subsidiary seconds dial is positioned at 6 o'clock, and the display is complemented by blued steel Breguet hands.

Movement and Mechanics

The oscillator consists of a cut bimetallic compensation balance paired with a blued steel flat balance spring and an index regulator.

The movement is marked with the seal of Geneva quality mark, confirming its compliance with regional standards for fine manufacture. The auction description notes that the movement is numbered, matching the numbering convention found on the case.
