Bluejay 179 · November 9, 2019

Serial Number 1062004 was reported as inaccurate.

Note: Larger than a 12 size. May be a 14. But
certainly smaller than a 16 size. When I was
taking it apart to clean, the movement wouldn't
fit in a 12 size movement holder and a 16 size
movement holder was way to large. Thus, my guess
is a size 14 movement.
