I've had two consecutive watches, that on servicing, the barrel arbour screw has sheared off in the arbour, this is the first time this has happened. One of the movements had no identifying calibre, except the letter "M", the dial on the watch denotes it as a REGENCY. The second is an, AS 1123, I managed to purchase another arbour from cousins, but the first one is stuck fast. 

Any ideas......

I thought of using a watchmakers screw extractor. First you would have to soften the arbour by heating it, the drill through the pinion on the other side leaving enough wall thickness for the pinion still to function. You would now be able to use the extractor that grips the screw at both ends. A bit of a long shot, but it is a possibility.

If successful, you would then have to harden and temper the arbour before fitting to the watch.

I saw this on another forum, it gives you three possibilities.

      Depending on how much of the screw is left, you may be able to screw it further in and it may fall out of the hole that the dial foot sat in. To do this I rough up the tip of the good screw and screw it in, often the rough surface of the good screw and the rough surface on the broken screw get enough of a bite to transmit the torque into the broken section and force it out the other side. Like I said the size of the broken screw needs to be in your favor, but you never know you may get lucky.... or if you get it moving you may be able to then back it out with a screwdriver taking a bite on the rough surface. worth a try

      I will try this weekend.  I've tried several times with my cell phone and it's just too small and recessed to get a good picture.  I need to get my macro lens and tripod out and then figure out how to get enough light down the hole in the side of the man plate to  actually show the top of the broken screw. I appreciate the effort and will try and get that pic this weekend.

      Hi,   My name is Simeon I am based in Sydney, Australia and have recently got into watch repair / watch making.  I am very much a learner having serviced multiple forgotten watches, some of which were actually successful!   I have a slowly growing collection of watches, mainly old Soviet, a few Japanese and (not pictured) some Raketas, a Poljot Alarm, an Omega Speedmaster Reduced and a vintage (1972) Tissot Seastar.  I like unloved vintage watches, with quirky faces and enjoy bringing them back to life through the simple(!) act of disassembly, clearing and reassembly. I am an Electrical Engineer who also undertook a trade apprenticeship so I am reasonably handy - It's fair to say, I know just enough to get myself in trouble.
