Note: My movement is very unique for a model 1908. All
the screws are gold as is the regulator. Movement
reads... 17 jewels double roller W.W.CO
Waltham Mass
Near the winding wheels it reads ... Adjusted to
temperature and 4 positions.
All of the writing on the movement is inlaid
gold.
This is a very odd movement indeed. I have never
seen a Waltham marked this way or seen one with
all gold screws and regulator.
