<p>The invention relates to a mechanism for indicating the running reserve for a spring mounted in at least one first spring barrel (10a) comprising a differential (16) which is provided with a first mobile input rotatable during winding of the spring, a second mobile input (17) rotatable during unwinding of the spring and a mobile output (18) rotatable in a first direction during winding of the spring and in a second direction during unwinding of the spring, at least one first (24, 25, 26, 27) and one second (28, 29, 30) display trains which are connected to said mobile output and extend to an indicator (32a, 32b). The inventive mechanism also comprises a counting unit actuated by the mobile output (18) of the differential, wherein each display train is successively moved by said unit for indicating complementary lower and top fractions of the spring running reserve, respectively.</p> |
