Blancpain Leman Tourbillon Grande Date Diamants (Ref.2825-4963-55B)

Prestigious, complex and created by the most expert craftsmen, the Blancpain patented “rail-effect” gem-setting on the Leman Tourbillon Grande Date Diamants made a striking entrance on to the watch making scene in 2006, associated with Blancpain Calibre 6925, a self-winding large date tourbillon movement with a 7-day power reserve.

Since 1735, Blancpain has presented a considerable number of world firsts. The Manufacture in Le Brassus is pursuing this path by regularly introducing major innovations in the field of horological complications, the performance of mechanical movements, the functionality of the watch, design, and now in the world of jewellery.

The original and exclusive “rail effect” gem-setting on the dial of the new Leman Tourbillon Grande Date Diamants is entirely in keeping with this philosophy of constant innovation. Blancpain has conducted considerable research in order to develop this new gem-setting style – for which a patent has been field – 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 Leman collection, featuring an understated effect.

Focused around the heart of the tourbillon, the harmoniously curved motif illuminates the dial paved 194 diamonds totaling 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 Leman collection house 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 beveling of the components, along with Cotes de Geneve 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-chased platinum oscillating weight.

The white crocodile leather strap is equipped with a white gold folding clasp.
