Rolex Oyster Tru-Beat 6556 Silber Crosshair Zifferblatt

-----

The forgotten doctors’ watch…

This is a very rare and important vintage Oyster that dates to the 1950s. One of the rarest Rolex complications out there. Only created in a short period.

The ‘Tru-Beat’ was one of the first dead-seconds wristwatches ever offered. Instead of the flowing seconds hand that one normally sees on a mechanical watch, dead-seconds calibres tick once per second. What sounds very simple is incredibly complicated and requires a new escapement that allows one jump per second of the seconds hand instead of the usual five ‘beats!

The watches were marketed as medical professionals to accurately calculate a patient’s pulse. It is rare to see one of these watches survive as servicing is very complicated and parts scarce ! It is said that even Rolex converted some to regular movements.
This watch still has the deadbeat second hand movement and the 1040 movement is still fully working.

The case remains in great condition.

The silver dial remains in excellent original condition and the watch has a blued seconds hand. The rivet link Oyster bracelet reference 7205 is in very good condition and has ref 57 endlinks and a clasp stamped ‘1 69’. The watch has been fully serviced by our watchmaker.
