Telescopic ring assembly for case of watch, has extraction unit whose switching part is interposed between control rod and ring on which manual pressure is exerted for passage of retracted position to extraction position or vice versa

摘要

The assembly (1) has a barrel (10) for extending a telescopic ring (2) and slidable in a housing (4). An end (11) of the barrel comprises an internal zone (12) that is dimensioned to rotate an external zone (13) that is shaped corresponding to a shape of a control rod (3). An extraction unit includes a switching part (15) that is interposed between the control rod and the telescopic ring on which a manual pressure (FF) is exerted by a push-button for passage of a retracted position (I) to an extraction position or vice versa.
