1976 CWC G10 watch

[tumbledown]

 

 

Hi,

I have just received a 1976 G10 Cabot watch, I'm having difficulty opening the thing. It appears to be a snap on but under the magnifier

there are no gaps between the base plate and the housing. Could anybody give me some advice?

Thanks.

It's a long time since I've had one apart, but from what I remember the backs are incredibly tight.  You will need both a heavy duty back opener for opening it and a case press for snapping the back on again.  

Here's what I used to remove the back on the one I worked on.

Reveal and work the gap with a razor blade, cautiously.

No, no, no! The 1970's G10 is a tonneau case. Front-loader. Remove the crystal using a crystal lift. Stem is a removable type, so just pull hard on the crown.

 

The later Quartz G10 from 1980 onwards has a snap-on back. Use a strong case opening kife for this.

Good advice rodabod, it must have been one if the later versions I worked on.
