The present 40mm Chonomètre à Résonance rendered in 18K pink gold may look at first glance like a coveted “Boutique Edition” – but it’s actually far more rare. Aside from the fact that the boutique exclusive combination of black dial and pink gold case was not produced until 2010, if you tilt the watch a few degrees towards a light source, the wearer is instantly delighted by an array of iridescent colorations, varying in depth. Instead of a mere black dial, the dial is in fact crafted from a thin slice of natural black mother-of-pearl.

Found on the interior of mollusk shells, it is prized for its beauty but venerated for its strength; its molecular structure resembles plate armor. Historically it has been used to adorn a variety of decorative objects that also endure significant use, such as weaponry, cutlery, and tablewear, amongst other things. Black mother-of-pearl, also known as Tahitian mother-of-pearl, is more costly and rare than its white counterpart, occurring once for every ten thousand natural white mother of pearl shells.

The limited series made for the 50th anniversary of the historic Singaporean retailer Sincere Fine watches included, in 18K pink gold, 10 Chronomètre à Résonance (RN), 5 Tourbillon Souverain (TN), 10 Calendrier (Q), and 5 Octa Divine (D). Rarely seen publicly in any of the models, the black mother-of-pearl almost disappears until the light hits the dial at just the right angle and it’s as if the sun has set and the sky is awash in oranges, pinks, blues, and purples. It holds the duality of subtlety and flair.

Complete with its certificate of authenticity and warranty, as well as all of its original accessories, the present Chronomètre à Résonance made for Sincere Fine Watches is a rare opportunity to own one of F.P. Journe’s, rarest, most innovative, and visually captivating creations.
