The invention also relates to a method for rapidly changing the configuration of the aforementioned watch, in which, by pressing against the cover of the watch case, an elastic force arises from the spring, breaking the lock and pushing the removable capsule along the guide, to which the retainer serves.
EFFECT: ease and speed of replacing the clock-operated capsule without compromising the integrity of the case, the design of the watch is greatly simplified, and the performance of the watch is improved.
