ROSCHENBOLD's watches are powered by Seagull calibers from Tianjin Seagull. This company has been making mechanical movements since 1955. It offers a wide choice of complications unparalleled by any other manufacturer in terms of value.
However, we don't use the movements as delivered by the factory. We perform a complete disassembly, full check-up, lubrication, and replacement of some critical components. These procedures bring them to our required level of quality. After assembly, each and every one goes thru a 10-day regulation period.
The result: a +10/-10s variation (compared with its +20/-30s original specs) which gives us the confidence to offer you a Five-year warranty.
