Rate adjustment
Test 1 displays the current value of the rate correction.
This correction is calculated then saved in the movement
during production tests.
This test is also used to modify this correction value if
necessary. Every connection between the battery’s + pole
and the C+ or C- test points increases or decreases the
correction value and therefore adjusts the watch rate.
