In the late 1990s, Daniel Roth was once one of the most important horological brands in the trade. Known for its superior movements and unusual design, their timepieces were an instant sell out and the brand was a proven success. In the early 2000s, Daniel Roth’s brand was bought by Bvlgari and later converted into their own watch collection, bringing the production of Daniel Roth branded watches to a halt, limiting their existence today.

The present watch is a very beautiful example of a Daniel Roth’s timepiece, with its iconic tonneau-shaped case contrasting with the guilloché-work on the dial, it is a desirable piece of a very important moment in modern watchmaking.
