Good video! Wish you had shown the under cutting process in more detail as I’ve never seen it done and believe most of us hasn’t. I assume that you’ve used a bow to turn the screw? I always thought e should use the screwdriver as turning mechanism but completely wrong I presume was I.
Hey Robert, fair question! I think the technically correct answer is that since the hairspring is a Breguet, this would reduce the length of the terminal curve too much and maybe keep the regulator from functioning. More honestly, I have never actually re-studded a hairspring and this was less stressful to me.
Firstly, what’s your name? Fantastic video! However, lots of questions and observations. I love the vocals, you explain stuff really good and clear. But I miss close ups like taking the spring off, getting in beat etc. Love your tools! Could you explain how you roughly got in beat and how you accurately did that. Seeing which way you need to rotate the collet. Close up of using the undercutter. I have since looked on eBay for undercutters and poising tools! I’m really looking forward to working my way through all your vids!
Hey Boyd, my name is John. Thanks! Yes you're totally right. Right now I'm just using my phone but if I want to really do this then I need to upgrade and work out a permanent camera placement. Thanks for watching and for your feedback! I will do a video on beat setting soon - that's a great idea.
Hey William. That was actually the objective in this video. The watch was running about -1000 s/d slow with good amplitude and the regulator pins correctly spaced. I believe the wheel and balance spring were paired together by someone at some point in the past, without being vibrated. So the objective was to poise the wheel while simultaneously removing weight.
Hey Jimmy, I actually have never done it before. I have been reading about it in preparation to do it on the Bunn, so you will see how it goes there! I think it sounds hard and time consuming, but it really is the correct way, since poising the balance without the hairspring collet will not get it perfect. There are lots of weird errors of poise that occur when the hairspring is attached, so I think there is a good rationale for trying to dynamic poise it. But it all depends on the quality of the watch and how much work you want to put in. For most wristwatches and cheaper pocket watches I think static is totally appropriate.
"So I finally got the watch working, and it's working quite nicely, but there's a big problem, which is that the watch is not keeping time". I find it really funny that a watch can work "quite nicely" but not do the one thing it's designed to do 😂
Timothy, not sure if you are into servicing watches: to get a 7 jewels to work with a high amplitude after rebushing and cleaning is quite rewarding. We call this state as the watch working ‘quite nicely’!
I'll be darned! Poising a badly warped wheel on my rare Elgin 280. You're right, it's very helpful seeing someone else's take on things. Great work!
Thank you my friend :)
Great video, I did not know there is a tool to shave weight of a balance wheel screw from the inside of the screw. Thank you for sharing!
Thanks for watching Emil! Yes, you should be able to find them under "balance screw undercutters."

Why not shorten the hairspring?

@@timelyvintagewatches thanks John, I’m getting through your videos!
"The screw slots on these screws are actually quite large," he says while wearing an eye loupe so he can actually see them clearly. 😄
Hi, how much total weight did you remove?
Much easier and safer to add weight screw washers to the light side. What is removed cannot be added back.

Hi John, what's your view about dynamic poising? I've read that some people skip static and jump straight to dynamic dynamic poising?

I'm confused. I thought the purpose of those screws was to adjust the balance of the wheel. Why would you need to lighten one?

Haha yes! "Working" is a continuum, but "is it a watch" is 0/1.
