CAL. 51900

In the Portugieser Tourbillon Mystère Rétrograde, the retrograde display of the date automatically jumps back as you move from the 31st to the 1st of the month. In the months with fewer days, the hand can be moved forward thanks to a quick adjustment mechanism. The indication of the 7-day power reserve displays the residual energy of the manufacture caliber 51900. Watch enthusiasts especially appreciate the unusual staging of the flying tourbillon, consisting of 82 elements, in the form of a "living twelve". The tourbillon rotates around its axis once every 60 seconds to compensate for the imbalances caused by the force of gravity on the balance and the consequent precision difference. The transparent sapphire crystal case back allows you to admire the manufacturing movement with a three-quarter bridge in finely decorated nickel-plated nickel silver. The Portugieser Tourbillon Mystère Rétrograde in platinum with a silver dial is accompanied by a black Santoni alligator leather strap.
