We follow premium Swiss watchmaking standards without the “Swiss Made” stamp. We invest in real materials—904L stainless steel, sapphire crystal—and precision. Every Swiss movement we use (STP / ETA / SELLITA) is regulated in-house, moving from factory spec (~±12 s/day) to a real-world target of ≤ 5 s/day. Less marketing, more watch.
Our Standards
A note from the Founder
At Mazzo Watches, precision isn’t a claim—it’s a process. We choose 904L stainless steel, sapphire, and Swiss movements, then take them further in-house, regulating each watch to a ≤ 5 s/day target and pressure-testing to it's spec.
We don’t print “Swiss Made” on the dial; we earn the standard in the workshop. Tight tolerances, clean assembly, and final QC on fit, accuracy, and water-tightness—piece by piece.
If you value engineering you can feel on the wrist, welcome.
