First introduced to the market in 2006, the Trio Grande Date by Vianney Halter was created much inspired by the dashboard of a steam engine. It is the third model in the Futur Antérieur collection following on from the Antiqua and the Classic model. Cased in a white gold rectangular curved case, the present watch houses the rectangular VH205 calibre fitted with a ‘mysterious mass’ sapphire rotor, which was designed specifically for the Trio collection. The watch features the time, day and night indicator and the date is displayed through two riveted porthole apertures. The grand date mechanism alone comprises over 50 components and can be operated through the crown only, making the watch very convenient to use. The date and time setting mechanism is independent; setting the time does not interfere the date, hence reduce the risk of damaging the movement. Visually interesting and houses an exquisite mechanism, the present watch is a very fine watch indeed.
