Catalogue description

Dealer description — Oliver & Clarke

Universal Genève was one of the many great brands that succumbed to the quartz crisis of the 1970s. While they disappeared, it was not for their lack of impressive watches. To underscore that fact, keep in mind that Henri Stern Watch Agency in their nearly 80-year history has only ever sold two brands: Patek Philippe, and Universal Genève. The piece that we have here is something incredible special and rare. Dating to circa the 1940s — a time when the world was at war, this oversized timepiece stands out from many of its contemporaries not just because of it's size, but because of the unusual and bold dial configuration. Known to collectors as a 'Cairelli Split,' these pieces were produced by Universal Genève for the Italian Military (both Navy and Air Force) for astronomic navigation. That is to say, navigation at night. The nickname comes from the name of the Rome-based distributor of these pieces, A. Cairelli, which is prominently featured on the lower half of the dial. The dial itself utilizes a 24-hr layout for clarity in timekeeping, along with a high-contrast silver base and bold black numerals. The movement, a Valjoux Cal. 55 by Valjoux, was modified by UG to run in this 24-hr format, as well as for the subsidiary register at the 3 o'clock position to log 16-minutes, rather than the more common 30 or 60 minutes. The hour and minute hands are of the 'Breguet'-style and executed in a gorgeous blued-steel finishing — as is the four chronograph hands. The case comes in at roughly 44.5mm in diameter to accommodate the incredible movement within. The lugs feature beautiful curved-profiles and also nicely curve down, lending for a much more comfortable wearing experience than the case dimensions would suggest. The square pusher at the 2 o'clock (or rather, 4 o'clock) position is to operate the split-seconds function once the chronograph is running. All three of the main chronograph functions, start, stop, and reset, are operated via a monopusher embedded within the winding crown at the 3 o'clock position. Being a wristwatch fitted with a Valjoux 55 is, in any capacity, a delight. It enjoys its status as one of the earliest Rattrapante calibres to be fitted into a wrist watch, and can only be found in a select few timepieces. It is estimated that less than fifty of these pieces were produced, likely with a handful lost to time. As such, these simply do not surface on the open market all that often... and with the recent re-launch of the brand, collectors seem to be holding on to great examples of all Universal Genève models, making this a very rare opportunity to acquire one.

Historical context

Golden Age of Mechanical Watchmaking (1900 – 1945)

The wristwatch displaces the pocket watch; waterproof cases, self-winding and grand complications.

The wristwatch overtook the pocket watch. Military use in the First World War, aviation, water-resistant cases (1926), automatic winding (1923–31), rectangular Art Deco designs and early chronographs and calendars defined the period.

Atlas type guide

Chronographs and split-seconds watches

A chronograph is a watch with an additional seconds hand that can be started, stopped and returned to zero independently of the timekeeping. Louis Moinet built an early example in 1816 and Nicolas Rieussec a recording 'chronographe' in 1821; Adolphe Nicole's heart-shaped reset cam (patented 1862) made the modern return-to-zero possible. Split-seconds (rattrapante) chronographs add a second hand that can be stopped for intermediate times; flyback chronographs restart instantly.

Chronographs were essential tools for doctors (pulsometer scales), artillery (telemeter), engineers and sport. In wristwatches, Valjoux, Venus, Lemania and later the automatic chronographs of 1969 (Zenith El Primero, the Chronomatic Calibre 11 group and Seiko 6139) are milestones.

What to look for

  • Push-pieces on the case band or a single button in the crown (monopusher).
  • Subsidiary registers for minutes and hours; tachymeter, telemeter or pulsometer scales.
  • Column wheel versus cam control visible in the movement.
  • Calibre markings of specialist makers (Valjoux, Lemania, Venus, Landeron).

Dating clues

  • Pocket chronographs with heart cam reset: after 1862.
  • Wrist chronographs: from c. 1910; two-button designs from the 1930s.
  • Automatic chronographs: from 1969.
