swiss hallmarks
I know this is pretty fuzzy, but can anyone decipher these hallmarks on my old Zenith ww?
Thanks,
Steve G.

OOps, I guess I'd better attach the picture...

Hi Steve

I think I've got the three in the center:

Left one: 925 = sterling silver
right: import mark for London
bottom: date letter 1931 if this is a 'q'

Please try better picture; write us the numbers below the DEPOSE on top, this should be a patent number.

My watchmaker, Philip, has the watch right now making a stem for it. I will look at it again as soon as I get it back. Thanks a lot, Gerald!

Here is the Zenith dial-obviously needs cleaning.

Here is the movement.

Maybe some astute historian can figure out a date chart by comparing the serial numbers with the hallmarks on some of these swiss pieces.

And the movement. Can anyone identify this design for me?

What does the little fern design in the lower right signify?

The second watch can also be dated by the three marks in the center of the case back:

.925 :sterling silver
cross,diagonal :import mark of Edinburg
third mark : date letter 1929 if 'x'

Yes, I think it is an X, and that would be consistent with the style of watch-wire posts, etc, from that time teriod. Thanks very much!
