Hello all just want to make a quick introduction. My name is David and I am an avid watch collector mainly divers and chronographs from the late 50's to mid 80's being my preferred vintage. I have always tinkered with all things mechanical and after rebuilding a 1982 Porsche 911 engine with nothing more than a book and some online help I figured I can tackle most any job. I recently put together a watch from off the shelf parts using a cheapie ETA 2824-2 clone movement which worked fine until one day the stem came loose when changing the date. I decided that as it was a cobbled together project there was no way I was taking it to my watchmaker but rather would tackle the repair myself. I disassembled the watch and found some information which pointed toward the keyless works bring the problem. Sure enough after taking off the dial and date wheel parts it was indeed the keyless works. I stripped this out and on examine the parts could see how poorly made they were so I ordered NOS parts. I got the new parts fitted them back and voila problem solved. I have since repaired another old Fortis five watch I have had for years which had a similar problem although this just requires resetting the works. I have now taken a huge leap and have stripped down a valjoux 7730 movement out of an old wakmann I have had for years which has never really worked properly. Only thing I have found broken at this stage is the mainspring and the flyback lever which I have ordered. I am however struggling to find much information or service advise on this movement. I know it is similar to the Venus 188 but is it that similar? Anyway if anyone can help I would appreciate it.

      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. Thats interesting about synthetic oils , i thought the same, going from a 2 year service to 5 years is a big drop in income for service folk.  I expect some did well when they embraced the use of synthetic,  probably drawing in more customers than those that didn't use the new fangled substances , i bet fairly short lived though. The more frequent service makes more sense to me, not for just the service but for the regular check up inspections that might pick up impending faults. As far as epilame goes, wouldn't it be great to be able to fumigate the complete movement in a sealed jar of heated stearic acid, 🤔 now theres a thought 😅.

      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.
