One of One
Most jewelry is made to be sold many times over. Ours isn't. We source rare vintage and estate watches you won't find in a display case anywhere else, and what we don't source, we make ourselves. Either way, the piece in front of you is singular, not pulled from a production run. When you buy from Assay, chances are no one else on earth owns its twin.
Featured on...
At Assay, we’re proud to be featured as top sellers across multiple marketplaces (1st Dibs, Chrono24, Etsy, Rubylane and more). No matter where you prefer to shop, you’ll find the same exceptional products and service available on every platform!
