Led by Patek Philippe expert John Reardon, we guide collectors in making confident vintage watch decisions.
Winner of WatchPro 2024 Vintage and Pre-Owned Retailer of the Year.
We make buying and selling vintage watches simple, transparent, and authentic.
We offer properly vetted, historically significant watches for serious collectors.
Every timepiece is personally inspected and authenticated by our founder, John Reardon, one of the world’s leading experts on Patek Philippe. The case, dial, movement, and, when applicable, the buckle and bracelet are examined before a watch is offered for sale. Whenever possible, we include the original Certificate of Origin or an Extract from the Archives. If a watch is offered without one, we will always explain why - for example, if Patek Philippe declined to issue an Extract from the Archives because a dial was changed at some point in the watch's history.
We take pride in offering watches in the condition in which we acquired them. We avoid unnecessary interventions such as polishing or dial refinishing. If a movement requires repair, it is serviced by our select group of trusted specialists, including Patek Philippe-trained watchmakers.
Yes. We guarantee the authenticity of every Patek Philippe timepiece we sell. If a watch purchased from us is ever determined to have a previously unknown issue, please contact us to discuss the issue. This authenticity guarantee lasts two years from the date of sale and applies only to the original purchaser. It covers the watch as a whole, not individual components. All trademarks mentioned are the property of their respective owners. Collectability is an independent business and is not an authorized Patek Philippe dealer nor affiliated with Patek Philippe SA.
Every watch purchased from Collectability is guaranteed to be in working order for one year from the date of sale. If it stops functioning properly during that period (and hasn’t been damaged or mishandled), we’ll repair or adjust it free of charge.
Vintage and pre-owned watches should never be considered water resistant, even if they were originally designed as such. We recommend avoiding exposure to water, shocks, or magnetic fields.
For most timepieces, with the exception of consigned pieces, if you decide your timepiece is not right for you, you can return it within three business days for a full refund. We’ll provide a return shipping label and issue your refund upon safe receipt of the watch.
We accept secure payments via bank transfer only.
Yes. All shipments are insured until they reach you via a trusted courier.
Returns are accepted within three business days of delivery for a full refund. We’ll provide a prepaid label and issue the refund upon safe receipt of the watch.

Within the first year, repairs within reason are covered. After this period, we can coordinate servicing with our watchmaking partners at your expense, with an estimate provided before any work begins.
