Abstract
The stop second device during precise time-setting of a watch fitted with a tourbillon (1) comprises mobile elements such as levers (14, 15, 16) mounted in the carriage (2) of the tourbillon, each of said mobile elements being returned by a return spring (28, 29, 30). These mobile elements are capable of contacting the periphery of the balance (3) of the tourbillon, to block said balance when action is exerted on at least one of said mobile elements by a shoe (17) arranged outside the carriage (2) and controlled by the time-setting stem (26) of the watch. The outer edges (18, 19, 20) of the levers are located above pillars (4) of the carriage (2), such that the shoe (17) can act on the levers without interfering with said pillars.
Claims8
A device for stopping a watch-movement during time-setting, said watch movement being part of a watch and comprising a tourbillon, said tourbillon comprising a rotating carriage inside which a balance oscillates about a rotational axis of the carriage, said device including manually controlled blocking means for stopping said balance by acting on a peripheral zone of said balance, wherein said blocking means include mobile elements mounted on the carriage and capable of entering into contact with the periphery of said balance in order to block said balance when action is exerted on at least one of said mobile elements by an element that is arranged outside the carriage and controlled manually from the exterior of said watch.
A stop device for the set-hands mechanism of a watch fitted with a tourbillon, said tourbillon comprising a rotating carriage inside which a balance oscillates about a rotational axis of the carriage, said device including manually controlled means for blocking the balance in its peripheral zone, wherein said blocking means include mobile elements mounted on the carriage and capable of contacting the periphery of the balance in order to block the latter when action is exerted on at least one of said mobile elements by an element that is arranged outside the carriage and controlled manually, and
- wherein each of said mobile elements is a lever, the first end of which is pivotably mounted on the carriage and the second end of which carries a pad capable of blocking the balance when a shoe, controlled by a time-setting stem, exerts a pressure on the lever, each of said levers being returned to a rest position by a return spring.
