Music is at the root of the Raymond Weil brand, so it’s no surprise that the company’s newest addition to the Nabucco collection is a cello-inspired watch created by chief executive officer Elie Bernheim, who’s played the instrument since he was a child.

“My grandfather’s lifelong love of music combined with my own passion for the cello are the two elements that inspired us to design and develop the Nabucco Cello Tourbillon, which is intended as an expression of our brand’s imaginative approach to watch design,” said Bernheim, whose grandfather founded the brand in 1976.

The watch, which will retail for $39,995, features sapphire crystals on both sides. The movement bridges supporting the tourbillon escapement and mainspring barrel take on the form of the instrument’s distinctive f-holes. The slender hands are formed in the shape of a cello bow and the five lines of a musical stave are represented in a grooved bezel. Four tiny strings are stretched taught across the dial combining with the f-hole shaped bridges to create the illusion of miniature instrument.

Only 10 of these watches, which are available in May, will be produced.

Bernheim was named ceo of the brand last year. He succeeded his father Olivier Bernheim, who became president of the board of the company and will serve as a consultant.
