Device for setting watches

A device for setting watches arranged to be temporarily pressed onto a crystal of a watch comprising:

• plural display means,
• wherein the device is arranged to enable a user to see the display means of the watch during setting of the watch;
• the device further comprising:
• at least one indexing mark for angular indexing thereof with respect to a reference of the watch;
• and
• for at least one particular display of the watch, at least one complementary piece of information relative to the particular display of the watch to facilitate the setting of the particular display concerned.

A method for setting a timepiece assembly including a timepiece movement and a setting device, the timepiece movement including control means including main and secondary control members and display means for displaying information, the setting device being arranged to be pressed onto a watch crystal to enable a user to see the display means of the watch as the display means are set, the device including at least one indexing mark for angular indexing thereof with respect to a reference of the watch, and additionally, for at least one particular display of the watch, at least one complementary piece of information relative to the particular display, the method comprising:

• a) pressing the setting device onto the watch crystal;
• b) activating the main control member to place the timepiece module in a setting operation mode in which parameter setting phases are effected in an iterative manner, each phase b) comprising the following b1)-b3):
• b1) displaying the parameter set during the phase by a movement of the display means;
• b2) selecting the value of the parameter by the secondary control members;
• b3) validating the parameter value by acting on the main control member;
• c) exiting the setting operation mode when the parameter value of the last phase has been effected and entering a normal operation mode.
