Description

The Chronometre Observatoire Only Watch 2015 is a piece unique created for the Only Watch Auction. It features an aluminium case and dial; as if not rare enough, the bridges of its L200 movement are also made of aluminium.

Despite its unusual aluminium movement plates, the present watch is one of the first of the 'new' Leroy (no longer L.Leroy) watches to be made commercially available.

Movement

Leroy caliber L200AL Hand-wound movement presented at BaselWorld 2015, feauring a direct impulse escapement, a balance spring with a double terminal curve and a 'Brun Cage', enabling the balance-spring stud to be modified by 360 degrees. It features jumping seconds, though not in the regular sense; the so-called 'duplex jumping seconds' make a big jump followed by a shorter jump. The power reserve is indicated through a diamond-shaped aperture on the dial at 9 o'clock.

It is said the theoretical power reserve of this movement is 150 hours; it was however limited at 98.

The present version was created especially for Only Watch 2015; its movement plates are made of aluminium
