A TRANSPARENT CASE BACK FOR
AN EXCITING REVEAL
By offering a watch that reveals its movement through a transparent case back, Rolex continues to innovate whilst echoing its watchmaking tradition. Calibre 7140 bears a cut-out oscillating weight in 18 ct yellow gold with three arms, engraved with the words ‘Chronometer Perpetual’ and benefiting from an optimized ball bearing. The movement boasts some remarkable finishes including the exclusive Rolex Côtes de Genève – a celebrated traditional watch decoration, reinterpreted with a polished groove between each band. The window, made of virtually scratchproof sapphire, provides proof that, for Rolex, the aesthetics of the movement are as important as its performance.
