About Vesuviate
Vesuviate makes tool watches aimed at active wearers and pursuits such as diving, flying, racing and sailing. The brand emphasises durability through a thermochemical surface treatment that hardens the material itself rather than applying a coating that can peel, and says it draws on more than three decades of experience engineering exotic materials for harsh industrial environments.
