Secondhand Mods is a boutique parts store specializing in OEM and aftermarket watch parts. Parts are in like-new condition, never worn and in limited quantities. New parts are added daily. We also sell used and even damaged parts. These parts are marked accordingly in their product descriptions. If you're interested in selling your own parts on the site, please contact us at

Like many of us, Secondhand Mods began as a hobby and quickly evolved into an obsession. Watch modding has so many wonderful elements to enjoy but parts can be prohibitively expensive making the hobby a challenge to sustain.

By sourcing our parts from fellow modders like yourself, Secondhand Mods can offer the same parts from your favorite suppliers but at much lower prices.  
We operate and ship out of Oakland, California. 

Thank you for your support and please let us know if there's anything we can do to improve the customer experience.
