Can't tell from these images if it's a rubbed in or pressed in jewel - you need to look at the outside where you apply the oil. 

If they are rubbed in, then assuming you have the tools, the hard part will be finding a new jewel. You need to open the setting before removing the old jewel.  I spoke to a local watchmaker about this and his advice was that money was better spent on a donor movement than buying collections of old jewels as most of the useful sizes have been used up.

Well, I too thought they were rubbed jewels and then I thought it must be a view of the flat side of the jewel so not possible to be sure...


If it's rubbed in, what should the other side of the jewel look like so I can have a look and compare. I do have the tool to open the setting g but do not have the tool to close and burnish it closed!

One can use a hollow stake from the set or grind a hollow punch with the desired pitch and diameter. For the 4 jewels i replaced until now i had to make 2 stakes. Soft steel will do, use oil while opening and closing the setting!

      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
