About Synchron

In 1999, Rick Marei revived the Synchron name with a clear purpose: to bring forgotten Swiss watch brands back to life. The original Synchron, founded in Switzerland in 1969, had pioneered the idea of grouping multiple watch brands together and steered Ernest Borel, CYMA and DOXA through the turbulent 1970s. Marei saw an opportunity to do the same thing for brands that had disappeared.

Marei was already ahead of his time—he was one of the first people to help Swiss watch brands sell online. But his real passion was resurrecting iconic dive watches that were all but forgotten from their golden era. He is widely recognized for the rebirth of DOXA SUB and under his leadership, Synchron has brought back legendary names like Aquadive, Aquastar, Tropic straps, and ISOfrane, making them available to collectors and enthusiasts again.

The approach is straightforward: stay true to what made these watches special in the first place, but update them so they work for today’s collectors. Synchron continues that mission as an independent watchmaker, creating timepieces that honor the past while embracing modern craftsmanship.
