Rolex Tru-Beat retailed by Tiffany & Co., Reference 6556
LOT 143 - 10 May The Geneva Watch Auction: ONE
An exceptionally rare Rolex model, the Tru-Beat reference 6556 was launched in 1954 as a tool watch for doctors and healthcare workers.
It’s the only mechanical Rolex model to ever incorporate a "dead-beat" seconds mechanism that advances the seconds hand only once per second. This permitted more accurate readings of patients' pulse rates, however the demand for such a timepiece was quite low, and the reference was soon discontinued. Amongst the small quantities produced, few have survived with the dead-beat mechanism of the Rolex caliber 1040 still intact.
The present example functions exactly as Rolex originally designed, with a seconds hand that perfectly advances once every second. The silver, sectorized dial, dauphine hour and minute hands, and red-painted seconds hand are immaculately preserved, making this one of the finest ref. 6556 to appear on the market in recent years.
