Serial Number U844285 was reported as inaccurate.

Note: This one is not marked or listed as a BWR, however
it is marked as (A8P) and I believe it would be
safe to show the 571 grade as being:
Adjusted to Positions = 8 or 9
instead of 5....

Note: Movement marked 8 ADJUSTMENTS...this does not
mean 8 POSITIONS...there are also Temperature and
Isochronism adjustments to be considered
