Patek Philippe Annual Calendar Flyback Chronograph 5905P-010

Partially verified

This Patek Philippe Annual Calendar Flyback Chronograph, reference 5905P-010, is a modern automatic wristwatch produced in the 2010s. The case is constructed from platinum and measures 42 mm in diameter. It features a glossy black dial equipped with luminescent hands and white gold markers, displaying annual calendar functions—day, date, and month apertures—alongside a flyback chronograph complication. The movement is the automatic caliber CH 28-520 QA 24H, which incorporates a column-wheel mechanism and adheres to the Patek Philippe Seal standard; it is visible through the watch's sapphire crystal case back. A distinguishing design detail is an inset diamond on the case at the 6 o'clock position. The watch is completed by a black alligator leather strap with a platinum buckle. The flyback function enables the user to reset and restart the chronograph without pausing the ongoing measurement.

Object description

Case and Dial Design

The Patek Philippe 5905P-010 features a 42 mm platinum case. A distinctive element of this model is the placement of an inset diamond within the case at the 6 o'clock position. The timepiece is paired with a black alligator leather strap secured by a platinum buckle.

The dial is finished in a glossy black tone, providing a backdrop for luminescent-treated hands and white gold indices. The layout includes an annual calendar display with day, date, and month apertures, alongside a chronograph sub-dial at the 6 o'clock position.

Movement and Complications

The watch is powered by the automatic caliber CH 28-520 QA 24H. This movement features a column-wheel mechanism for the chronograph function, which is designed with a flyback capability, allowing for continuous timing without stopping the mechanism.
