Abstract
The tool, which can be adapted to a bracket for fitting hands on a dial by driving them in, including a lower rod (11) which slides in a tubular part (13a) of an intermediate cylindrical element (13) compressing a spring (33) abutting against first tension adjustment means (43) and with an overlap that can be checked by a movement indicator (34) for a first force F1, said intermediate cylindrical element (13) itself sliding in the upper tube (15) compressing a second spring (35) abutting against second tension adjustment means (45) and with an overlap that can be checked by a movement indicator (36) for a second force F2.
Claims9
A dual effect compensating tool, able to be adapted to a bracket for fitting hands on the dial of a movement by driving them in, including at its base a stake screwed into a lower rod, and at its other end an upper tube onto which a head is screwed, allowing a force F to be exerted, wherein the lower rod slides in a tubular part of an intermediate cylindrical element compressing a spring abutting against first tension adjustment means and with an overlap that can be checked by a movement indicator for a first force F1, said intermediate cylindrical element itself sliding in the upper tube compressing a second spring abutting against second tension adjustment means and with an overlap able to be checked by a movement indicator for a second force F2.
