Catalogue description
Dealer description — Bulang & Sons
Founded by Louis Brandt in La Chaux-de-Fonds, Switzerland, in 1848, Omega has grown into one of the world’s most celebrated watch manufacturers. Milestones in its history include the revolutionary 19-ligne calibre of 1894, the launch of the legendary Professional Trilogy in 1957 and the Speedmaster’s historic journey to the Moon on the wrist of Buzz Aldrin in 1969. Offered here is the elegant Omega ref. 14904, introduced in 1960 as part of the International Collection. While the Speedmaster was conceived as a purpose-built tool chronograph, the International Collection offered a more refined and luxurious interpretation of Omega’s chronograph expertise. Produced for only a brief period and discontinued by 1962, the ref. 14904 is a rarely encountered model today. The elegant 35.5 mm case, crafted from 18k yellow gold, remains in lovely condition, retaining its strong lugs, round chronograph pushers and screw-down case back. The silver dial features a beautifully balanced tri-compax layout with three recessed subsidiary dials, an outer tachymeter scale, applied baton hour markers and elegant non-luminous dauphine hands. Its restrained design perfectly reflects the sophisticated character of the International Collection. Powering the watch is Omega’s legendary hand-wound calibre 321 — the very same movement that powered the earliest Speedmasters and accompanied astronauts into space and onto the surface of the Moon. Regarded as one of the finest chronograph movements ever produced, it remains a favourite among collectors to this day. The watch is paired with one of our Bulang & Sons leather straps and has been fully serviced by our watchmaker, ensuring it is ready to be enjoyed for many years to come. While the Speedmaster conquered the Moon, the ref. 14904 quietly showcased Omega’s more refined side. Powered by the legendary calibre 321 and produced for only a brief period, this elegant chronograph presents a wonderful opportunity for the discerning collector. Get in touch!

Historical context
Modern Mechanical Horology (1945 – 1969)
Tool watches for divers, pilots and astronauts; electric watches anticipate the electronic age.
The classic era of the mechanical wristwatch: dive watches, chronographs for motor racing and space flight, GMT watches for jet travel, slim dress watches, automatic calendars, and the rise of Japanese manufacturers alongside Swiss, American, German and Soviet industries.

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.
