Rolex 4160

High confidence

Mechanically the most complex movement Rolex has made, and operationally the least intuitive: the Ring Command bezel is part of the setting mechanism rather than a timing bezel, so the watch is programmed by rotating the bezel and using the crown together. Worth knowing before handling one — an examiner unfamiliar with the sequence can conclude the watch is faulty when it is behaving correctly.
