The day and month discs follow suit in matching grey, creating a harmonious and modern aesthetic. These subtle contrasts come alive under changing light, while the dots of the minute track and Dauphine hands, coated in Super-Luminova®, glow discreetly in the dark. On this signature display, the jumping date between the 15th and 16th day stands out, made recognizable by its anchor-shaped tip – a subtle reminder of the Maison’s logo – finished in bright red. This small detail of great refinement facilitates reading of the indications. Capture all the nuances of time with this resolutely contemporary watch, created in a limited edition of 500 timepieces.
