Original drawings
Mr. Gérald Charles Genta’s case design
The Maestro 3.0 Chronograph is a one-to-one representation of the Gérald Charles Genta’s original drawings, with the exception of the previously round pushers that, taking now the typical and asymmetric Maestro case's shape, represent a creative advance.
“Maestro”
Original design by Mr. Gérald Charles Genta
Crown
Screw-down crown with Clous de Paris finish and embossed logo
Construction
Carved with CNC numeric control machinery. Asymmetric polygon with smooth edges
See-through case back
Case
10 ATM water-resistance
Mr. Genta designed the Maestro case taking inspiration from 17th-century baroque architecture by the Swiss-born Italian architect Francesco Borromini. The ‘smile’ at 6 o’clock is a subtle reflection of the concavity on the monuments’ façades. The screw-down crown and the bespoke gasket enable the timepiece to be water-resistant to 100 metres.
