Hi I have a B.W.C. Co. Gold watch I was told it was solid Gold and it has the Hallmark of a Lion.
The movement has no name anywhere on the movement. Can someone help with the content of gold marking and movement. Thanks.

Here is the Gold hallmark Thanks.

Hi, Gary:

The Brooklyn Watch Case Company commonly made low karat gold cases (commonly 9K or 10K) but to know definitively would require testing.

A quick "field test" would be to gently use your thumb and forefinger to flex either cover--if it bends slightly without much effort you could generally say that your case is solid gold. A gold filled case with an underlying base metal will greatly resist any sort of bending or flexing. Another way is to examine either the pendant for brassing or the case edges near the hinges or area near 6 o'clock where wear is most readily apparant (a 10X loupe is a good investment).

I checked all over it and took it apart no brassing anywhere and after movement moved there is a rouch cuedging that looks solid gold. It does bend on the lids. Thanks

I searched the web "B.W.C.co. with lion mark" and found several discussions about these cases. Some of what is said is that they were made by the Brooklyn Watch Case Company before there were requirements in this country to have gold marks. They say they have been tested and are 14K solid gold. I read that Jones Horan auctions has auctioned watches in the past with this mark and stated they were 14K.

Now I don't know this as fact, just what I found.

That mark assays to 14K Geno
