I got this golden tuna (7c46) with stripped case threads.

Does anyone have any suggestions on how to get this fixed?

I'd need to find someone that can laser weld titanium and then tap the proper threads...

I tried a different crown to verify that it is in fact the case that is shot.

It is not a 6309. See the thread (excuse the pun) on another forum, with various useful answers already.

None of which have yielded anything... that's why I've posted about it here. The steps to fixing it are clear, however finding a person with the tools and experience is proving to be the challenge :)

With all the due respect, I think the replies given reflect well the problem, and I don't think that the steps to fix it are so clear as you think.

So where do we go from here... I'm a fan of getting things done. It seems there are only handful of ways to go forward, but again, I haven't been able to find a watchmaker to tell me: "I can fix this, it will cost you this much"

Maybe because it can't be fixed, or can't be fixed properly. Not everything is possible, or practically possible.

That is repairable but you need to find someone with the right skills, and specific tools for that thread, its a case of tube extraction, and then dulling existing worn threads, then re-tapping the threads again with an offset tap with the correct pitch.

I have a feeling this is one of those cases where the cost of fixing the problem would be above the value of the watch.

      Epilame / Fixodrop

      By Neverenoughwatches · Posted

      Yes i did eventually realise that the oil will act as a barrier, I'm sure the discussion will continue. Ive had two oleophobic coffees ( added coconut ) and in the meantime i have this just delivered to take my mind off epilame for the time being. My favourite type of dial, its a beautiful looking watch traditional English made and it runs,  the ticktock is phenomenal,  i can hear it across my living room .  You wont believe how much it was.

      AS2031-57E solar panel - mission: impossible

      By Albyon · Posted

      Imm going to close the discussion by attaching the photo of my super-titanium after several vicissitudes finally working. Purchased as not working I replaced the battery and for a stroke of luck I found its semi-new solar panel which, having verified its operation, seems to recharge the accumulator perfectly. I had taken this watch almost by bet, with 40 euros I brought it back to life. The initial half idea was to resell it to finance another purchase, but.. it's definitely a nice item. It would need to check the impermeability but it's a pleasure to see it on the wrist 😃

      Insert the movement inside the case

      In fact the secret is to go gently and find the way without forcing, and the movement enters without problems

      Sure! Some very accomplished repairers never use epilame! I have often wondered if it is worth the trouble. Not using epilame will shorten the service intervals though, but that could be better perhaps both for the owner and the repairer!? Speaking of oiling, I just read this: After WWII in the 1950s the first Synthetic Oils came on the market. Most watchmakers did not rush to use these oils since they were bad for business now that the watch serviced with Synthetic oil would not come back to him for service for another 5-7 years he would lose a lot of income. ~Ofrei.com   Anyway, I wouldn't be surprised if it would be more correct to think of epilame as a binder rather than a repellant. Until convinced otherwise that's how I will think of epilame.
