Serial Number 16495953 was reported as inaccurate.

Note: My watch says "W. W. Co. Waltham Mass. Adjusted",
and "17 Jewels", and is a Gold case. Inside of
the (outer) back case says "J. W. C. Co, Trade
Mark," (with a moon and a star), Serial
"2059531". Inside of that cover, is another cover
that says "Warranted, Crescent, 25 Years" , Serial
Number "2059531". On the inside of the Front Cover
is the Serial Number "205931". The inside back
frame is stamped Serial Number "9531". Any info
would be greatly appreciated! Thank You...Ted L
