Crafted entirely in white ceramic, the J12's 38mm round case is paired with a matching white ceramic bracelet secured by a fold-over clasp with safety release. A unidirectional rotating white ceramic bezel and screw-down crown complete the exterior, while a transparent case back offers a view of the movement within. The case measures 11mm in thickness and carries a water resistance rating of 200 metres.
The white dial is laid out with black hands — luminous for low-light legibility — and Arabic numeral hour markers accompanied by minute markers along the outer rim. A date window sits between the 4 and 5 o'clock positions, and the scratch-resistant sapphire crystal protects the dial face above.
At the heart of the watch beats the Kenissi/Chanel Calibre 12.1 automatic movement, comprising 28 jewels, oscillating at 28,800 vph, and delivering a power reserve of approximately 70 hours. This example is from 2024 and is offered with its original box and papers.
