A paragon of fine Swiss watchmaking, Logical One is Romain Gauthier’s Grand Prix de Genève-winning creation that contains a revolutionary snail cam and friction-minimising ruby-link chain, plus sapphire-lined mainspring barrel, to offer nearly two days of constant force – the holy grail of precision watchmaking.

Its beautifully hand-decorated, in-house movement can be admired dial side and through the display back, and is wound using an ergonomic winding pusher integrated into the caseband. It features hours and minutes on an off-centre subdial, small seconds, and a 46-hour power reserve indicator on the back.

Logical One Black Titanium features a black ADLC titanium case and anthracite ADLC treated movement. It is available with an oven-fired white enamel dial complemented by flame-blued steel hands, or an oven-fired black enamel dial with red accents complemented by 18k white gold hands.
