Abstract: A winding and setting arrangement for a timepiece comprises a two-part stem extending through the hollow shaft of the spring drum. The outer part of the stem is affixed at its outer end to a crown and at its inner end has Breguet teeth which, in an inner position of the stem, are engageable with Breguet teeth of a connecting member which is non-rotatable but axially movable in a cavity in the hollow spring drum shaft. A spring urges the connecting member outwardly against a shoulder in the shaft. The inner part of the stem is coupled with the outer part by a square section so that the two parts rotate together but are axially movable relative to one another. The inner stem part passes freely through the connecting member and, inwardly of the spring drum, carries a pinion which is engageable with a setting wheel in an outer position of the stem. A spring urges the inner stem part outwardly.
