The Competentia 1515 model, whose movement is made entirely from solid gold or platinum, is equipped with a power reserve indicator, a service indicator, a day/night indicator and a one-minute tourbillon. Despite the complication level, this calibre does not exceed 5 millimetres in height, to ensure that the watch remains comfortable to wear, though adorned with a dial comprising eleven enamel parts. This model also has a service indicator at 12 o'clock where an enamelled gold oil drop symbol appears after four years in operation, when the timepiece must be serviced.The decoration of the central disc of this dial employs the subtle technique of plique-à-jour enamelling, so as to show glimpses of all the refinements of the movement decoration. To achieve this effect, transparent enamel is delicately laid onto a gold structure, before being fired in a furnace at over 800°. The peripheral indexes, a modern vision of 16th Century clocks, are made from enamel and gold.
Competentia 1515 is available in platinum or 18ct gold, red 5N, yellow 2N or grey Pt125. It comes on an alligator strap with a pin buckle in the same metal as the case. Gem setting on demand.
