A New Old Stock example (and freshly serviced) of the 1972 MicroQuartz by Roamer: an interesting, independent, robust and innovative, audible ticking quartz movement using a electromagnetic escapement six years before Rolex did in its OysterQuartz or Omega in its MegaQuartz. Besides this, Roamer made its quartz beat at the back then quite unusual- but todays standard-rate of 32'768Hz.

This is what we call an important watch and an horological milestone. We assume this was the rolex- & role-model for the Rolex Oysterquartz: a highgrade mechanical-engineered movement with a reliable, time-proven, longlasting and robust escapement-mechanism.
