SUMMARY

Launched in 2021, the Patek Philippe ref. 5905A is a thoroughly modern interpretation of the watchmaker’s annual calendar. It’s constructed of stainless steel (not something we commonly see from the brand) and features a green dial - a colour which has featured heavily in recent watch releases. The case measures 42mm in diameter and is paired with a three-link bracelet, the first time it’s been incorporated into the range. The striking green dial features central hours and minutes, a chronograph sub-register at 6 o’clock, and three apertures across the top to display the annual calendar. Behind the sapphire crystal case back is the Patek Philippe calibre CH 28‑520 QA 24H, featuring a 21K gold central rotor with the Patek Philippe seal.

All watches offered for sale are searched and cleared against The Watch Register database and a certificate is available to the winning bidder upon request.

Any watch not covered by a current sales or service warranty should be considered as potentially requiring a service, even if in full working order on the date of purchase.
