Abstract (en)
[origin: EP2166419A1] The movement has a kinematic chain connecting a barrel (1) to an end of a balance-spring, where the chain is formed of a driving gear (4), a pinion (5) and a wheel (6). Another kinematic chain connects a time base to another end of the balance-spring, where the other chain is formed of a second mobile (13) and an escapement wheel (16). Each chain includes a wheel mobile (9) with an adjustment body (20). The body includes a peripheral tooth (41) defining a support surface, where the tooth acts on the surface to turn the body.
