b. Make sure that the hands are adjusted so that there is equal space between the hands and the hands are set as close to the dial as possible.
c. Check to be sure that the hands are shaped to the contour of the dial.

Check Number 15

a. If there is no case for the movement, simply disregard this check and proceed with the next check, number 16.
b. Check for proper snap/screw back of the case.
c. Check for the clearance of the hands under the crystal.
d. Check the crystal to see that it is securely fitted into the case.
e. Check to see that the crown is next to the stem and reasonably close to the case.
f. Check for tightness of movement in case.
g. Check the spring bars to see that proper spring bars are used for the particular type of case so that the band is held securely to the case.
h. Check the lug holes to see that they have not been worn badly by the spring bars to a point where the hole may break through and allow the spring bar to come out of place.

Check Number 16

a. Set the watch on time with a master clock.
b. Let the watch run for a period of 24 hours and check the error in the time repeat in several positions.
c. Allow the watch to run until it completely runs down and check the length of run. The watch should run a minimum of 30 hours, preferably 40 hours, if it is in “A. 1” condition.
