This Daniel Roth Master Perpetual Calendar, reference 118.X.040, is an 18k yellow gold wristwatch featuring a double-ellipse case measuring 35mm by 38mm. The watch displays a grey dial with a hand-finished guilloché chapter ring containing Roman numerals.
It includes calendar indicators for day, month, leap year, and date, along with a moon phase display. The movement is an automatic Calibre DR114, which the source notes was modified for Daniel Roth. The watch is presented on a leather strap with an 18k yellow gold Daniel Roth buckle. Developed by Daniel Roth with Philippe Dufour during the 1990s, the design aimed to incorporate an instantaneous perpetual calendar mechanism, though the production model features a standard perpetual calendar complication.
This specific example is identified as an early execution from the manufacturer's formative period.

Design
- Case and Dial
- The watch is housed in an 18k yellow gold case described as having a double-ellipse geometry measuring 35mm by 38mm. This design incorporates a distinct rounded profile with protruding lugs. The case construction reflects the manufacturer's signature style established during its formative years. The dial is grey and features a hand-finished guilloché chapter ring adorned with Roman numerals. The arrangement of the perpetual calendar complications—including day, month, date, leap year, and moon phase—is designed for symmetry and legibility. Blue steel hands indicate the hours and minutes, as well as the calendar functions.

- Movement and Complication
- The watch is powered by the automatic Calibre DR114. The movement was meticulously modified for Daniel Roth and adheres to the finish standards observed in the brand's early production. The movement is visible through the caseback. The perpetual calendar complication originated from a design collaboration between Daniel Roth and Philippe Dufour. While the pair initially aimed to develop an instantaneous perpetual calendar, the energy demands required for such a display were not met, resulting in the perpetual calendar mechanism found in this example.
