The collaboration
GMTOne is built in collaboration with Watchinist — watch specialists from Luxembourg. The platform brings the technology; Watchinist brings the horological eye that keeps it honest.
Watchinist lives and breathes watches. That sensibility shapes how GMTOne curates — which references get featured, and what a serious listing should look like.
From how conditions are described to what belongs in a spec sheet, the platform's listing standards are shaped with people who actually collect and trade.
GMTOne and Watchinist share a home base in Luxembourg — at the heart of Europe, serving collectors across the continent.
