Serial Number 860525 was reported as inaccurate.

Note: The description is fine, but the drawing of the
movement does not match. I also see the same
problem on some of the Grade 587 watches that
other users have. The movement I have has a fake 3
finger bridge, i.e. the bridge has been machined
to look like it has 3 separate fingers/bridges,
but in reality they are not fully cut so they are
one bridge. Maybe their was a run that had solid
bridge and a run that had the fake 3 finger.

Curator Response: Thanks for the report. This was the second-to-last known run of 587 movements. It is possible Rockford switched to the 3-finger train bridge to finish out production. The last run appears to have been manufactured the same way. If possible, please upload photos to provide documentation for future researchers.
