Gem-setting technique: Blancpain patent
The original and exclusive "rail effect" gem-setting on the dial of the new Léman Tourbillon Grande Date Diamants is entirely in keeping with this philosophy of constant innovation. Blancpain has conducted considérable research in order to develop this new gem-setting style - for which a patent has been filed - with a view to breathing fresh life into contemporary and dynamic variations of jewellery watches. This gem-setting is presented as a world first on the Tourbillon Grande date Diamants model of the Léman collection, featuring an understated effect.
Detailed view of the dial
Focused around the heart of the tourbillon, the harmoniously curved motif illuminates the dial paved with 194 diamonds totalling 1 carat/ The lugs and bezel are also set with 166 diamonds (~ 1,8 carats).
The outward radiance of this exceptional timepiece is matched by its interior beauty. The Tourbillon Grande Date Diamants in the Léman collection houses Blancpain Calibre 6925, a mechanical self-winding movement with a 7-day power reserve, composed of 307 components. This subtle mechanism, in addition to its remarkable flying tourbillon visible at 12 o'clock, features a large date display at 6 o'clock, along with the usual hour and minute hands. Representing the signature feature of Haute Horlogerie models, the bevelling of the components, along with Côtes de Genève and circular-grained decorative motif, are just some of the manual operations performed by craftsmen with golden hands and amazing dexterity.
The white gold 38-mm diameter case of the Tourbillon Grande Date Diamants is water-resistant to 30 metres. Its sapphire case-back enables one to admire the finishing work lavished on all the parts and to contemplate the to-and-fro motion of the hand-chases platinum oscillating weight. The white crocodile leather strap is equipped with a white gold folding clasp.
