Building further on the mechanical concepts introduced in the Decimal Minute Repeater calibre, which strikes the hours, ten-minute intervals and minutes, this creation incorporates additional developments made at the request of a private client.

The Masterpiece retains the clear, highly legible seconds display at 6 o’clock found on the previous model. It is now complemented by a 24-hour second-time-zone indicator positioned at 12 o’clock. The day- and night-time discs of this indicator are engraved with stylised sun and moon motifs in 18K yellow and white gold.

The mechanism is actuated directly via the crown: a short, clearly perceptible push advances the second time zone by one hour.

The hand-guilloché 18K rose gold dial features two contrasting fields, while the case is entirely crafted by hand using 18th-century methods. This approach delivers striking visual results and is also one of the key elements in ensuring the full sonority of the two gongs.
