One of the most beautiful watches in the world


In LEROY's LIMITED SERIES is one of the most beautiful time pieces in the world - the Les Grandes Heures Jewellery L110/10.  Adorned with 425 "invisible set" diamonds totaling over 9.5 carats the watch is absolutely spectacular.

On the business end nestled in all those diamonds is a flying tourbillon with variable-inertia balance with four gold setting screws and double balance-spring, diamond escapement, non-lubricated StruTech blank (61 components for 0.8 grams).

The in-house movement, a Cal. L512 Manufacture Leroy has a diameter of 28.80 mm (12.8’’’) and runs at a frequency of 28,800 vibrations per hour (4 Hz).  It has 23 jewels with a power reserve of over 52 hours.

The movement sports hand-chamfered bridges decorated with Côtes de Genève, sunburst 22 ct gold oscillating weight.

It received an official chronometer-certification by the Observatoire National de Besançon and is stamped with the "Viper's Head".  This is a numbered piece with production and pricing available on request here.
