Let's modify a watch together!

Your watch is more than a timekeeper — it’s an expression of who you are. At Prosper Watch Co., we specialize in transforming timepieces through bespoke modifications that honor craftsmanship while adding a personal touch.

Whether it’s a treasured heirloom or a new discovery, we’ll work with you to design a look that’s uniquely yours. Our process begins with a complimentary 30-minute virtual consultation, where we’ll discuss your vision and outline the possibilities.

We proudly work with Seiko, Miyota, ETA, and quartz movements, with the flexibility to explore most other watch types as well.

Bring your timepiece to life in a new way and wear a story that only you can tell.

Note: Purchase of this item is for the assembly of modified and custom watch parts into a watch. The watches depicted are not for sale nor included in the service of this sale.
