For its first participation in the 6th ONLY Watch charity auction to take place on November this year, Tudor has decided to reinterpret one of the least known tool-watches in its history: reference 7923. Launched in the mid-1950s and produced in tiny quantities, this is the brand’s only divers’ watch to have been equipped with a hand-wound movement. It also stands out from the other divers’ watches produced by Tudor with its baton-type hands. Highly sought after by collectors today, this rare reference was an excellent starting point for the creation of a one-off model destined for this unique initiative. The Tudor Heritage Black Bay One created for this auction mixes the best of both worlds —vintage and modern— in a flawless execution. This unique piece Tudor Heritage Black Bay One created for Only Watch 2015 is part of Tudor's heritage inspired approach, reinterpreting the reference 7923 with enlightened freedom.
