There is an enormous thread about microscopes that goes into all the details you might ever want to know for watchmaking (or nearly so). Toward the end, you'll find the most current links and suggestions for the model(s) that are best/least expensive for task, but it's worth reading the thread on your way to those links.

I doubt the one shown in the PP first post is very suitable for use in repairs, inspection maybe but not repairs. Plus you will do damage to your neck with those vortical eye peace's.

I would suggest saving a little longer and buying one of the more common types.

Look for things like Stereo, trinocular, simulfocus plus add a low cost video camera, I found having one to be a boon whilst leaning even if it's only to a record of where all the bits came from, just record the stripdown and then play it back as you assemble after cleaning, that option saved the day on more than one occasion .

This is the one I went with and from a UK seller so next day delivery, if you search eBay you will find them in the usual cream colour from Chinese sellers for under £200, all you have to add is a Barlow lens 0.5 to give a greater working distance, enough to get screwdrivers ect under the lens  and a camera, mine was under £50 and has enough resolution but a higher resolution would be a better choice and I will probably upgrade  mine someday, just to make the still pictures sharper but it's not so important in video.

If you can afford a version with a boom arm rather than the all in one stand go for it if you can.

But I have been using mine for a year now and can't fault it.

Hope this has been of help

If you register on the Amscope site they regularly send through clearance offers. Picked up an Amscope 3.5X-45X stereo microscope on a boom stand with an LED light and 0.5 barlow lens for £240 a month ago on a clearance deal.

The 0.5 barlow lens allows a good working distance and the boom arm is great for freeing up space.

I'd read a lot about the benefits of using a microscope but, without being overly dramatic, this has been a game changer for me.

    • I can try a big tweezer the biggest I had in my set didn’t do the trick but I’ll check if my wife has some none watchmaking ones. 
    • Yes, gum netal, which actually means iron. It is thick enough to be grinded in order to remove the rust pits and then polished, but it will need blackening oxidation in the end for protection from getting rusty. The watch has nothing to do with the railways, it is the same like the 'squirrel' candys - You do not really expect to find a squirrel inside...
    • I think the app is misinterpreted the noise because of the extra case construction    Tom
    • I have just picked up a vintage soviet Zarja watch and I have been inspecting it prior to putting it on the 'to be serviced' pile. When I measured it with the timegrapher app, I found it was gaining loads of time. Taking the case back off, I find it's a tiny movement within a relatively large watch and it has a separate steel cover over the movement which presumably holds it in place against the caseback.   Checking the app again without the cover, I find it is actually running reasonably well for an untouched old watch. Putting the cover and the caseback back in place and it reads as massively gaining time again. This behaviour is consistent every time I take the cover on and off. I have checked the balance cock is fixed and the screw is tight, so I assume that the cover and case back are pinching the movement in some way and making it run fast. Not sure I can see how that works because if the cover is touching the balance, surely it would make it stop not run faster? It can't be touching just the hairspring to make it effectively shorter.  Placing only the cover in place or placing just the caseback in place (not even snapping it shut) both cause the fast running. Pretty sure there are a couple of millimetres clearance between the case back and the movement when the cover isn't there. I have also checked the watch, cover and case back for magnetism with another phone app but none of them seem to have an appreciable magnetic field. Perhaps I need to preemptively demagnetise and get a real compass to check them with.  I appreciate that this is just an app using the built in microphone on my phone - could it be misreading a ringing / reverberation of this cover to give the wrong result? Observing the watch just running on the bench closed up, it does seem to be appreciably gaining time. I will wind it, set the time and leave it running overnight and see how it does with no cover / back in place. Perhaps I will also see how it performs on the wrist to rule out misreading by the app    What am I missing here?
    • OK, sometimes it really happens without problems at all. You can take a covex oilve 120/12 stone from Molnija 3602.
