This example remains in outstanding original condition with a good case and fantastic overall aesthetics., weighing a hefty 250 gram !The 40 mm case has 4 setting pushers on the side and two pushers for the chronograph function. The watch has a lovely rich blue dial with tachymeter scale, serif AP font and thin polished non luminous hands for minutes and hours and polished and white painted hands for calendar and chronograph function. The two different complications are integrated in the sunken sub dials. The counters at 6, 9, and 12 o’clock positions display the day, month, leap year, and date functions plus the chronograph function. The moon phase indicator is at 3 o clock. The watch is fitted with the original platinum braclet that will fit a wrist size up to 18cm.

Historical context

Mechanical Renaissance (1990 – 2010)

Mechanical watches return as cultural objects; independent watchmaking flourishes.

Mechanical watches returned as cultural and luxury objects. Complications, tourbillons and new materials proliferated; independent watchmakers such as George Daniels, F.P. Journe and Philippe Dufour revived artisanal watchmaking; collecting vintage watches became a major field.

Atlas type guide

Calendar, moon-phase and perpetual calendar watches

Calendar complications range from a simple date to the perpetual calendar, which automatically allows for months of different lengths and leap years until 2100. Pocket watches with perpetual calendars were made in the eighteenth and nineteenth centuries; Patek Philippe made the first perpetual calendar wristwatch in 1925, and series production followed in 1941. The annual calendar (Patek Philippe, 1996) needs correction only once a year.

Moon-phase displays use a disc with two moons and 59 teeth advanced daily, approximating the 29.5-day lunation; more precise trains reduce the error to one day in over a century.

What to look for

  • Apertures or subsidiary dials for day, date, month and leap year.
  • Moon disc under a 'bosom' shaped aperture.
  • Recessed correctors on the case band for setting the calendar.

Dating clues

  • Triple-date wristwatches: popular c. 1940–1955.
  • Perpetual calendar wristwatches: from 1925 (unique) and 1941 (series).
