Catalogue description

Dealer description — Oliver & Clarke

Ulysse Nardin was founded in 1846 by its namesake, a twenty-three-year-old watchmaker who set up shop in Le Locle, Switzerland. From the very beginning, Nardin was interested in producing high-functioning instruments that could be trusted at sea. That focus on precision soon turned the company into a quiet powerhouse among navigators. The marine chronometer became the brand's calling card, and it proved to be a serious business. Ulysse Nardin's chronometers were adopted by more than fifty navies around the world, and the company collected award after award for accuracy along the way. By the late nineteenth century, the name was synonymous with reliable timekeeping on the open water. With the rising popularity of wrist watches in the early twentieth century, UN adapted to the shift and carried much of what they had previously been known for into their wrist-bound timepieces. The piece that we have here is a chronograph Ref. 7536 dating to circa 1970. You may have noticed that it bears a close resemblance another chronograph from this era: the Rolex Daytona . Because of its striking similarities to the Ref. 6421, these have become known to collectors as 'UN Daytonas.' The similarities are not just limited to looks alone, inside these pieces utilize the same Valjoux 72 manual-winding movement as Daytonas from this era. The case comes in at 38mm in diameter and features very nice lug chamfers, 'pump' pushers, a screw-down caseback, and an externally-mounted black 'tachy' bezel. The black dial within has a matte surface with Ulysse Nardin scrip flanking an applied logo, applied 'faceted' indices, and silver 'concentric' subsidiary registers which lend themselves to that highly desirable contrast that we love about 'reverse-panda' dials. The Tritium plots exhibit a light and uniform patina and are matched within the 'stick' handset. Even in the world of vintage , UN flies under the radar and remain largely overlooked. A shame, because if you dig deep enough into their catalog, there are absolute stunners to be found. This piece offers looks, pedigree, and versatility and theres no saying when another like it may surface on the open market.

Historical context

Quartz Revolution (1969 – 1990)

Seiko's Astron begins mass quartz timekeeping; traditional industries contract sharply.

Quartz and digital watches transformed the market after 1969. Swiss employment collapsed, Japanese and Hong Kong production soared, and the Swatch (1983) helped the Swiss industry recover; mechanical watches survived as luxury goods.

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.
