I must admit, I’ve taken a fresh look at the dial and hands on the fake and they are wrong. Here is a genuine 1980 GS watch (Fatboy).
Imagine taking a ruler and drawing a line under the bottom of the 11 and 1 numbers and that would be the exact top of the CWC logo. Look at the positioning of the logo on the fake, it is higher.
Also the minute and second hand are not long enough, they only just reach the inside of the minute track instead of the outside of it like on the original. The crown doesn’t look right either.
All in all, it’s a bit of a dogs dinner, but at least we got it pulled from e-bay.
