Spring-loaded zeroing device

Abstract

A zeroing device 100 for a chronograph, having at least one zeroing heart 110, 120, a zeroing unit 200, which has a zeroing lever arm 210 and a zeroing lever bar 220, a first end 221 of which contacts the zeroing heart 110, 120, and a control means 130 which interacts with the zeroing lever arm 210. A zeroing of the zeroing unit 200 is effectuated by actuating the control means 130. This enables low production and maintenance costs and allows the counter hands to be reset to the zero position in a safer, more durable, and user-friendly manner. The zeroing device 100 includes a first compression spring 140 which is supported on the zeroing lever arm 210 and is) operatively connected to the control means 130. The control means 130 interacts indirectly, via the first compression spring 140, with the zeroing unit 200.
