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.
Part of Logical One Natural Titanium’s splendour lies in the contrasts created by the various finishes applied to the case and movement: light and dark, polished and satin-finished. The mainplate, mainspring barrel bridge and lower bridge for the constant force mechanism bear a deep anthracite ADLC finish. Yet, the balance bridge, escape wheel bridge and power reserve indicator bridge are in a bright palladium-treated brass that brings out the fine hand-finishing of these parts. Likewise, the upper ‘bar’ bridge for the constant force system is in light-hued natural titanium.
As for the titanium case, the lugs, bezel, caseback, pusher and time-setting crown are satin-finished, creating a gentle sheen that forms a fine counterpoint to the gleaming caseband, which has been highly polished. The alligator leather strap is in casual matte black with light grey stitching.
