<p>The set (100) has a toothing (108) that is formed at a periphery of a plate (103). Other toothing (113) is formed in a single element with the plate of the toothing (108) so as to reduce the problems of alignment in relation to other toothing and to decrease the overall mass of the wheel set made of metal or metal alloy and silicon based material. An independent claim is included for coaxial escape system for timepiece.</p> |
