Remove a stuck 1.20mm screw from a butterfly clasp

Hi! I've gotten this issue that I want to remove this butterfly clasp from this strap. But this tiny screw (I think it is 1.20mm) just won't move. The manufacturer's instruction said it should be turned counterclockwise to remove. I tried several high quality German and Swiss made screwdrivers of various sizes. I could get a tight fit of the screwdriver and used a lot of force pushing it down. But the only thing I achieved is stripping the head of the screw. I even destroyed two Bergeon screwdrivers in this process (twisted their heads).

Any advice is appreciated. Shall I use some penetration oil? Will they damage the leather next to it?

Thanks!

Are you sure it is a genuine one and not some reproduction. Many of these screws in fact do not screw in or out but are just dummies because they look good. As you have tried everything and buggered up screwdrivers and nearly taken the head off the screw It could be one of those dummies. Last resort a little WD40 might help.

This is a genuine strap and buckle from a MB&F MAD1. Their (pretty nice) instruction manual says that I could remove that screw by turning it counterclockwise. They didn't mention Loctite. I'll try some heat, penetration oil, and WD-40 and see if any of those could help. The situation that it is right next to leather limited my options.

      First pendulum clock tinker

      Grateful for info regarding the nature & function of the horizontal cog and the unit it's on top of in the picture. It meshes with a vertical cog (enclosed in the unit) on the arbour which is supported at its other end by the back plate of the dial unit to which it is not quite perpendicular...

      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

      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 😃
