I have just completed my second attempt at lubricating a watch movement. One of my biggest challenges is lubricating the pallet jewel since , as I lower the oiler towards the jewel, I can only see in 2D with my loupe. As a result I sometimes end up hitting the top of the jewel or reaching below it. 
Is there a trick to this or does it just get better/easier with experience?  I know microscopes are 3D but not in the budget right now. Do you just have to sort of feel around when using a loupe?

What magnification loupe are you using mark

 I oil the escape teeth with smallest bit of oil, let the watch run for few hours then add more oil, repeat as long as you gain amplitude.

Some folks oil the pallets before installing it, instal and  let the watch run for couple of hours, remove & rinse the fork, reinstall. 

There are threads on WRT that show images of oiling.

Angle your movement so you can see the impulse face of the pallet stone like this video shows

You might find it easier if you hone down the end of your oiler and put a slight bend on it. I find this helps when oiling pallets.

This is one of the best YouTube videos on this subject, which will definitely help. It is all about practice. Don't expect to get it right the first few times. 

I've just had a class of students in today and they were oiling the train wheels jewels for the very first time using stereo microscopes and by the time they got to the dial side and the very last ones they were getting the lubricant in the jewel without painting the top of the oil-sinks. Lubricating pallets is not the easiest thing to do, especially without a stereo microscope. The more you practice, the more you'll get it bang on.

4X. Also have a 12-15X loupe. 

For oiling the pallet stones or escape teeth i would need the 15 x loupe and have my nose pressed right up the movement in order to stand any chance of doing it without a microscope

    • Hi folks, I'm doing some homework on getting a watchmaker's lathe, and it's clear I have a lot to learn. But I know one goal: I want to be able to fabricate wheels, which would require an indexing capability. I know how to use large lathes- like, giant metal lathes- but my experience is a few decades old now (but you never forget the smell of the metal cutting oil). So I'm looking to learn anew, and have a goal to get to a point where I can fabricate some basic watch parts. I also have no specific timeframe and want to do this right, so I'll be patient and learn what I need to before spending the money. I know I'm not going to get anything for a pittance, but I'm also not really able to put together the scratch for a $5-$10k lathe. What's out there for a hobbyist that can either handle some fabrication out of the box or can be relatively easily made to do so? Thanks!  
    • Hello and welcome to the WRT forum.   This usually points to broken balance pivot.  Though a watch in need of clean & lube can do the same. Easiest diag would be to  see if balance pivot doesn't stay in hole jewel of the setting, when you lift one side of balance rim with an oiler or gently with pair of tweezers. Another would be to detach balance complete from the cock and take a look at pivot under high maginfication.  Regs 
    • Ahhh, yes.  I hadn’t thought of that.  I’ve serviced quite a few of these and the first time I didn’t realise it was a ships strike pattern!  Ha ha, confused me totally until I realised.

    • Hi Mike, I did, thanks. Found this clip that was really helpful:   It says Seth Thomas but it's actually the same Hermle I've been working on. I'd had it working correctly all along but hadn't noticed that the lever with the sprung end stops the hammer a bit short of the bell on the second ding at the end of the half-past sequence. If only I'd put the bell on when testing, rather than just looking at the hammer, my ears would have told me it was working,  even if my eyes didn't!
