Hi all.

 

I have a couple of old cwc g10 early models but I cannot get the backs off. see pics attached of the tools i have tried. 

There is only a very small gap to lever off but due age they seem totally stuck.

Can anyone suggest how to get them off.

any help greatly appreciated

Thanks 

Yes i did see your black caseback opening tool

the pics i posted shows the same tool but grey and red, the problem is there is no way the blade will fit as there is no gap, only a tiny indent at one point near the lugs so no chance of using this tool, infact i damaged the blade trying to force a gap but it just wouldnt budge.

On some snap backs there's no solution except resorting to a hammer. It's fiddly, you want the case in your hand, get knife in place holding with same hand (sometimes you have to start with a box cutter), and tap it in. Once the gap starts it gets much easier. Scary if working on a non shock protected mechanical but I've yet to kill a staff this way, quartz no problem.

Aha! so it justs needs a bit more force. 

I bought the heaviest looking case knife and a prising tool and nothing touches it. 

 

Will try a hammer and see if i can get it to move. The gap provided is very small so impossible to use any force trying to prise it. 

thanks all for the info.

Needs a cease opening knife and a watchmakers hammer. It WILL open. Put the watch in a small vice. Wrap it in a cloth to prevent scratching. Leave a small gap so the watch isn’t too tight. Insert the knife in the gap. Give it a firm tap. Increase tap pressure until it loosens. It will come off!!

      Been there. Worn that Tshirt.  'ping'. Hands and knees. Nothing. Nada. 20 minutes? Ha! I found it 7 month later. How? Well, after advice from a member, I invested in a £4 UV light torch.  Hands and knees looking for a 'ping' from a Sekonda, found them both within 30 seconds. UV makes the jewel shine. easy peasy. Could have taken longer. Just lucky on the location of the search. Hope this helps.

      Thanks Dell. I thought about silver soldering. Have never done it but would like to give it a go. Do you think to put flux on the butted joint then run the solder in or to maybe brace it with a piece of scrap spring steel?

      Never and others. Yes, like you I do spend a fair amount of time reading the contents of this forum. I find it better that any other. Clear, lucid, no Prima Donas, and most of all an easy access without adverts. All thanks to Mark. God bless you mate. You give so much to many of us. What if? No Mark? Hypothetically. A forum. I did run a forum for a few years. Really enjoyed it, but became so engrossed that it did affect my health. I gave to to others to run. Not been back. It was very successful and rivalled a number of large paying sites. No adverts, no others but me. I did ask and listen to members comments and it worked well.    Costs Having a domain name, £10 annually.  Register the site with a forum company, free. Build the site using the forum company guide lines, free. It looked and ran almost the same a Mark's. All the same facilities. The cost was only £5 per month, but counted visits (views). If I recall, it was that price for 5,000 views. Each extra 5,000 views increased the price by £2 per month. Success was my own personal undoing. From £5 per month initially, it rose to £60 a month and looked like increasing. This was 10 years ago. I could not afford that, and asked it anyone would like to take over and someone did. I would assume that this is the price that Mark is funding for us all. His return is our continued comments on the internet about his course, and the fact that many of the big names on YouTube mention him as their Tutor. Those of us who have done, and are still using, his course, benefit. In comparison to other courses, I can't believe how cheap it is, and the value is exceptional. It is the structure that gives the value. Long may Mark reign. Ross

      Hi all, total newbie to watchmaking and I've had a bit of a mishap. Just completing level 2 and was doing ok, but I was just on the last part of the reassembly of my ST3620 when the balance end stone shot across the room, just as I was trying to see if I had put the correct amount of oil between it and the balance end, aarrrgh! Been on my hands and knees combing the carpet for 20mins looking for it but to no avail. Does anybody know where I can get a replacement from and what to look for please?? Thanks.
