Instantaneous perpetual calendar with retrograde date Introduced to celebrate the 75th anniversary of the Reverso in 2006, the Triptyque required a team of technicians, engineers, designers and watchmakers over six years to develop. With 19 complications displayed over three-dials within a reversible case it was a worldfi rst and gained accolade as a suitable milestone for the anniversary. Five patents were sought for the various mechanisms including a new detached-lever (ellipse isometer) tourbillion within a titanium carriage. Altogether the movement consists of 642 parts with a HEIGHT of 7.5 mm.providing a 48-hour power reserve. The astronomical sky-chart could be requested as either a northern or southern hemisphere with the sunrise and sunset times calculated to the owners' location. The example offered is currently fitted with a northern hemisphere sky and calculated to Moscow. The massive case in platinum is fitted with a sliding lock to prevent accidental movement. This is the first example in platinum to be offered by Antiquorum.
