About Vintage Timepieces

Vintage watches often run smaller than today’s standards. Men’s wristwatches typically measure between 29–36mm (excluding the crown), while women’s models—especially from the early 1900s to the 1970s—can be considerably smaller. We encourage you to review the measurements provided and reach out with any sizing questions.

Our collection features timepieces that are 20 to 100 years old. Naturally, they may show honest signs of age such as light scratches, patina, or worn straps—features that often add to their unique character and charm. Unless noted as recently serviced, vintage watches may eventually require routine maintenance to keep accurate time. If you’re looking for quartz-level precision, a modern watch may be a better fit.

Pre-Owned Condition

We offer a mix of brand new and pre-owned watches. Pre-owned pieces might have some cosmetic wear, which we always describe clearly. Take a close look at the photos and don’t hesitate to message us if you have any questions before buying.

We do not use Photoshop to hide imperfections—only to clean up the background. What you see is what you’ll get. We take great care to present our watches honestly and transparently, and we’re proud to stand behind every piece we sell.
