Integrated chronograph by Dubois Dépraz

It is symbolically in the year marking the 50th anniversary of the famous Chronomatic/Calibre 11 – developed by Dubois Dépraz and unveiled in 1969 by three major watch brands – that the Manufacture de la Vallée de Joux is extending its range by presenting its first integrated chronograph.

Stemming from several years of development, the DD 540 calibre is the result of 118 years of experience in the design, manufacture and assembly of complicated movements, as well as chronographs that have become legendary.

Starting with a blank sheet of paper, Dubois Dépraz has chosen to give this chronograph a strong personality. This in-house column-wheel movement with its three-day power reserve indicates the time measured by means of a central seconds hand and two (hours/minutes) concentric hands sweeping around a single counter – a token of considerable technical mastery.

  • Movement DD 540: integrated column wheel, lateral clutch, automatic winding, 28,800 Al/H, 51 jewels, 32mm in diameter, 6.60mm thick

  • Functions: hours/minutes/seconds, chronograph with concentric 12-hour/60-minute counter, flyback function, power-reserve indicator (72 hours), aperture-type instant date display.
    At a time when differentiation is a mantra among brands, Dubois Dépraz offers a new opportunity to stand out from the crowd. Enriched by longstanding experience in perpetual calendars, already perfectly mastering the annual calendar associated with other complications, the Maison unveils an extremely understated new construction. The annual calendar is the heart of the complication, with only the date and name of the month appearing in different forms as indications.
    Built on the basis of an ETA or Sellita movement, this very useful complication can also be adapted on demand to Manufacture movements.

  • Additional mechanism DD 6000: 2 diameters to choose from (30 or 32mm), 4.90mm thick (with ETA 2892A2/Sellita SW 300 base), date window, month indicator window or hand.


These two new products will be presented at the world high-precision exhibition: EPHJ-EPMT-SMT (booth D43).
