Laurent Ferrier Galet Classic Tourbilllon Double Spiral Gem-Set Version

In this new sparkling version of Galet Classic Tourbilllon Double Spiral timepiece, 48 baguette-cut diamonds (3 carats) have been set according to a demanding technique representing a unique skill. Invisible setting is indeed extremely complex, with the diamonds mysteriously held in place as if by magic, thereby ensuring perfect harmony around the bezel. Moreover, the stones are arranged in such a way that they appeal to be moulded to the sapphire crystal. The combination of these two processes endows this creation with a highly distinctive aura.
The manual-winding Tourbillon Double Spiral calibre is an exclusive Laurent Ferrier movement distinguished by its concept two head-to-tail mounted balance-springs. This device serves to compensate for the effects of gravity by maintaining the centre of gravity of the balance aligned with its axis.

This movement with its timeless style is inspired by the great 19th and 20th century chronometry models. It features several nods to the competition watches that used to be testaments to the skills of the greatest watchmaking artisans, including a winding system with a very soft, pleasing design that does without the modern spring for the winding-stem pull-out piece lever.

The horological aesthetic also features a “long-blade” ratchet pawl and a smooth-polished finish. This movement is designed to be both accurate and robust. It has been carefully developed right down to the smallest details in order to find its way through time and successive generations, while testifying to an expertise going back more than 200 years. This finely hand-crafted model is also graced with a number of finishes, such as the many interior angles and smooth-polished surfaces.
