Help please. I have a 7s26A with a loose rotor bearing. The weight is rubbing on the case back. I've spent a couple hours looking everywhere for a replacement with no luck. I did find a rotor for a 7s36 on eBay. Would that one fit? Or if any one has a suggestion for an equivalent rotor with bearing or just a bearing, it would be very helpful. Thanks in advance for any help.

I know how you feel as I was in the same spot as you. In the end I sold the movement for spares and got a cheap seiko 5 with a good movement.

You can only use the 7s26a rotor, no other will fit. I don't know if the 7s26b and c variants fit...

I got my Seiko 5 for 12-14$ and it was functional, beat up on the outside, but functional and in good condition on the inside.

They all fit, including 7S, 4R, 6R and their SII equivalents. For details about 7S26 parts compatibility across versions check my table at: https://docs.google.com/spreadsheets/d/e/2PACX-1vRN2UULQKTfKmhRStZhDdIOIQrqd6sPB-g6x2SKyQQjOvTBjG_7TQXQhAT4f1WqAX5QAPkIimi-3jqd/pubhtml

I think I may love you. Do you have comparison charts for any of the older ref’s? I’ve made similar for the 7Axx range, although the file got corrupted and I’ve not tried to resurrect it yet, and I have a partial one for the 6139 series.

      Epilame / Fixodrop

      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.
