Offered is a highly collectible Patek Philippe Ref. 5100J “10 Days”, crafted in 18K yellow gold and dated 2000 — a reference firmly associated with Patek Philippe’s celebrated collector era.
The defining highlight of this example is its condition: the watch has just returned from a full official Patek Philippe service and remains factory sealed, preserving its pristine post-service state. It is fitted with a brand new Patek Philippe strap and is accompanied by complete service documentation, offering exceptional peace of mind and long-term collectability.
The Ref. 5100J is distinguished by its 10-day power reserve, displayed prominently on the dial — a technical achievement that reflects Patek Philippe’s mastery of long-duration mechanical movements. Its balanced, symmetrical layout and classical proportions make it one of the most elegant and distinctive complications of its era.
Included is an Official Extract from the Archives, confirming the watch’s production details, along with the original Patek Philippe box and service receipt documenting the recent factory service (approximately $4,000).
Examples that are sealed directly from Patek service are increasingly rare and highly sought after, particularly when paired with archival documentation. This watch represents an outstanding opportunity for collectors seeking provenance, condition, and long-term value in one acquisition.
