ABSTRACT:
A timepiece includes a flexible endless ribbon (10) bearing time indications (13, 14) and stretched between two parallel rollers (11, 12), and a mechanism for turning at least one of these rollers including a spring wound up inside a barrel, an escapement and a regulator member coupled to the escapement. The spring is wound up inside at least one of the rollers which thus forms the barrel of the drive mechanism.
