Abstract (en)
[origin: EP2230573A1] The mechanism has a secondary frame (47) integrated to a main frame (44). A support (38) is assembled on the secondary frame in a removable manner, and carries display chains i.e. indication beads (14, 15). Each display chain has an indicating link and a sapphire for assuring a function of a display unit. The chain is arranged on the support for being displaced along its length direction with respect to the support. A transmission unit formed of toothed transmission wheels (51, 52) and intermediate toothed wheels (54, 55) kinematically connects the driving unit to the chain. Independent claims are also included for the following: (1) a method for assembling a clock movement (2) a time piece comprising a case.
