First launched in 2003, reference 5101 features a large yet elegant stepped platinum case reminiscent of art deco aesthetics. At the time of introduction, the subtle tourbillon design was incredibly unusual compared to its contemporaries. In accordance with Patek Philippe’s design philosophy of aesthetic restraint and discretion, the model at first glance appears to be a time-only wristwatch. However, upon further inspection, the tourbillon carriage, visible through the case back, subtly rotates on its axis.

Reference 5101 is fitted with two complications that are very difficult to build within the confines of a rectangular movement and case, due to the lack of space. The movement features two tandem mainspring barrels with 240 hours of energy storage capacity, along with a tourbillon precision that comprises 72 individual components. The platinum example was replaced in 2009 with the release of the pink gold variant. Preserved in an attractive condition fitted with a classic salmon dial featuring masculine touch of blackened Breguet numerals, the present timepiece is offered with its Certificate of Origin and all its original accessories.
