39mm Calendario 18k WG Grey Dial Patek Serviced 2025

Here we have a 5135G Calendario that is in immaculate condition and comes with original papers dated in 2007. The case does have areas of mirror-like finish which are prone to hairlines (marks visible when with high resolution cameras or if angled at certain lighting). Pictures are part of the description so please refer to the pictures in determining the condition, pictures are of the exact watch being offered.

The watch was fully serviced by Patek Philippe in April of 2025, service records as well as service box will be included with the watch which implies a 2-year warranty from that date. The original box does not come with the watch.

The case is made of 18k white gold which displays a mirror finish as does the bezel mounted atop. Currently mounted on the watch is a Patek Philippe brown leather strap with matching stitching (approximately 85% condition) and that is paired with a Patek Philippe 18k white gold tang buckle. 

Functions are displayed on a grey dial that is accompanied by white gold applied hands and hour markers. Those functions include hours, minutes, sub-seconds, annual calendar, moon phase display and a 24-hour indicator. 

This watch has passed through our service center where it was first checked inside and out to certify its authenticity. After that, it passed a functionality test to confirm it is running up to manufacturer's standards and water resistant. Lastly, the serial number was run through a database to verify its legitimacy. We will issue receipts and a certificate of authenticity and test it once again prior to delivery. This watch will be backed by our in-house warranty as well.
