The Tonda 1950 Rainbow is exclusively available with a white mother-of-pearl dial. The logo, understated and slightly larger, stands out at 12 o'clock whilst remaining in keeping with the delicate dial design. The delta-shaped hands are skeletonised with a gilded outline which echoes the rose gold-plated indices.
The movement which drives the Tonda 1950 Stone-set owes its thickness of just 2.6 mm to an off-centred micro-rotor directly integrated into the main plate. This component winds the movement, which has an autonomy of 42 or 48 hours. This calibre was originally developed to allow for the addition of multiple functions without altering the slender proportions of the Tonda 1950 family — for example, a calendar or moon phase indication which could subsequently enrich the collection. This serves as proof of the excellent design of this movement and its successive variations.
