I have three watches that I want to talk about. The first is a Seiko 5 that was working quite well and I thought I could regulated. Unfortunately it's stopped. Newbie mistake. I've now sent this one in for service.

 

The second watch is a HMT Kanchan Frankenwatch. I bought it for about $10 on ebay. It has a couple of issues, and I don't mind if I break this one. The first issue is that it keeps Bad time while I'm wearing it even though it keeps good time when I leave it on the shelf. I have discovered that the rotor can cause the balance wheel to stop in certain positions. The other problem is that The day of week indicator is off. I will start by trying to fix the first problem.

 

The third watch is a Sea-gull ST5. This watch reports good time when I use an application like a Hairspring on the iPhone. However it loses a minute or two every single hour. Any advice as to what the problem maybe?

If the rate of the balance is correct (as reported by and timing app or Time Grapher) but the hands are consistently losing time then the most likely culprit is a loose canon pinion.

This is a relatively simple problem to fix but must be done with care as it is also very easy to overdo it.

If you do a forum search on canon pinion you will find a number of threads that deal with this specific issue.

I agree! I have ruined many a cannon pinion...Its easy to overtighten them, but once you know how, it is a straightforward issue to fix.

      Second hand watch market.

      By Neverenoughwatches · Posted

      Hello good watch folk ,I  just fancied a light hearted discussion after my head was starting to spin over Epilame 😅. Specifically I'm meaning the sale of vintage watches, say nothing past the 1980s market. The stuff we see on ebay and other similar sites and found at carboots, curio shops etc. And are  we thinking its reaching a peak volume ?  Younger generations clearing out passed parents and grandparents possessions.  The younger folk are not as sentimental as the old fogies ( I'm now nearly at an age that i used to think was old fogie age ). When might it have started ?  i often wish i discovered the hobby much much sooner when selling your grandfathers pocket watch at a boot sale for a few quid was just a way to offload some tat. And when might it slow down. Thoughts anyone ?

      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
