In the timepiece industry for an automatic movement / calibre or "engine" in the layman term, the second hand moves in a sweeping graceful circular motion, but not for this Rolex model 6556, whcih is well known for its infamous calibre 1040, the 'Dead-Beat' or Jumping Second, which moves at a constant rate in a ticking motion.
History reviewed that the production of Rolex Tru-Beat was to cater to doctors, healthcare workers or medical professionals, acting as a fashionable handy and portable instrument to wear it on their wrist and allow them to accurately measure the pulse rates of their patients. Alas, the market for this particular model was in low demand during that time, and it was discontinued five years later.
If you happen to encounter one but with it second hand sweeping smoothly, it is likely that the movement has been replaced.
