Catalogue description

Dealer description — Oliver & Clarke

Bucherer is perhaps best known today as one of Switzerland’s most prominent luxury watch and jewelry retailers, but the company’s history stretches back more than a century. Founded in 1888 in Lucerne by Carl Friedrich Bucherer and his wife Louise, the firm built its reputation on quality, craftsmanship, and an intimate understanding of Switzerland’s developing watch industry. By the early twentieth century, Bucherer had become an important retailer for many of Switzerland’s leading watchmakers. In 1924, the company established its long-standing relationship with Rolex, becoming one of the brand’s earliest and most important retail partners. Like other prestigious retailers of the era, Bucherer also developed watches under its own name, as well as branded other manufacturers' watches as their own. Eventually, this gave rise to the Carl F. Bucherer brand that we have today. The piece that we have here is dates to circa the 1950s and possesses many of what makes some of the most iconic chronographs from this era great. The case comes in at 35mm in diameter and features gorgeous chamfered lugs, ‘pump’ pushers, a screw-down caseback, and a signed crown. The dial inside, once silver in color, has developed an intense and largely uniform 'copper' patina over the years, making for a completely unique piece. It has minimal script on the top half with Bucherer's logo and name, 'concentric' subsidiary registers, applied rose gold-tone indices that alternate from 'dart’ to 'Arabic' style, and a rose gold-tone 'Alpha' handset typing it all together. Perhaps the most noteworthy aspect of this watch, however, is the movement inside. Powering this piece is the Lemania Cal. 2520, which is essentially the same movement as the iconic and significant Omega Calibre .321. Chronographs from roughly the 1940s through the 1970s are, for many, thought of as the essence of what makes vintage watches cool. Many of these models and brands have ascended to an unattainable level, making for completely under-the-radar finds like this quite rare. We think it’s awesome, and we’re confident we’re not the only ones.

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.
