How To Calculate Lift Angle Of An Unknown Watch Movement

I had a request recently from viewer Ammar Dalati on my Raketa 24 service video asking for a video on calculating the lift angle of an unknown movement, this is something that's quite straightforward to do and very useful especially when working on obscure movements and some old unlisted movements which the lift angle data is not readily available for.

That's a useful thing to know, I literally was in the dark about the lift angle concept

Glad it was useful, it's really only needed from a servicing and timegrapher perspective to correctly read the amplitude. An incorrect lift angle will give the wrong amplitude reading so for example if you have a watch with a lift angle of 40 degrees and you switch on your timegrapher which defaults to 52 you'll look like you're getting amazing amplitude when in reality you're not. It just all helps in interpreting the readings.

Tank you so much for making this video, I live in Turkey and we don't have Ebay here and watch making isn't really a common hobby therefore finding watches to practice on is difficult for me and I usually end up with some unknown movement, I've worked on alot of 6309 and 7009 and some Orients but I've had enough of those tbh, I'm relying on pc and phone applications at this point because I've started tinkering with watches not so long ago also I can't afford buying a timegrapher because I have been unemployed for a while (it's not easy finding a job in a foreign country) but I'll buy it the first thing when I find a job,I'll stop rambling now I'm sorry. Thank you again

No apology necessary. I love to hear about others journey with anything I'm interested in. The seikos are great movements for practice but are quite similar so it's nice to mix it up. Russian watches can often be had cheaply and though rudimentary movements they're quite nice and great practice, a well made Swiss watch is easy to work on once you've worked on a few Vostok and similar. A timegrapher is a great tool and the Weishi Chinese ones like this in the video are cheap and very good. Meanwhile the apps aren't bad, the real let down is the microphone that picks up the sound.

@@spidiq8 I couldn't find any Russian watches to practice on I guess they're not popular here, I have actually wirked on a couple swiss movements and they're really nice and easy to rap you head around them, I got my self a really cheap fake Rolex with a chinese movement in it and it's terrible there's no information about it on the internet and after spending hours and hours on it I gave up, the winding bridge has so many gears and pinios I couldn't figure out where they go😅😅

@@Ammar.D Yes, that's the other common Chinese movement, the actual seagull version are quite decent but the cheap clones are what you usually find in Rolex and Omega replicas. They're not bad for what they cost new but hit and miss quality wise.

In the slow motion video I can see the balance swinging 360°, not 180°. Please educate me as I must be missing something 🤔

@spidiq8 14 күн бұрын

Certainly, you're missing that we calculate amplitude from drop and lock of the pallets on each rotation. While the balance wheel rotates a full 360 degrees that's halved because the pallets actuate with each directional rotation and the point where the impulse jewel interacts with the pallet fork is about halfway in that full rotation clockwise or anticlockwise. Hopefully that clarifies things. It's trickier to put into words than show visually.

when you have a balance with two arms, I don't think you need the mark it... you only have to watch for the arms coming to the opposite position - you will have 180 deg amp then.

@spidiq8 4 жыл бұрын

You can but the mark helps immensely and makes it much more visible when it comes to the rest and return.

Maybe a timegrapher as weishi1000 is cheaper than a slow motion feature cell phone?

@spidiq8 4 жыл бұрын

The slow motion feature is simply an easy way to see the amplitude, it didn't replace the timegrapher.

IMO, Orient has better prices for tool watches than Seiko, but Seiko looks much better. My Orient Mako 2 holds up well when I walk into walls, or work on cars or small engines. If you’re going to bang it around, Orient is the better choice

@spidiq8 5 ай бұрын

Orient are fantastic and make some excellent watches at a price that honestly a lot of Seikos should be at. The popularity has driven some of them to ridiculous price levels.

so, slow motion to see the balance wheel travel rough degree, go back to toggle the "angle". Why not go straight to the movement maker as for a fact sheet? at least Seiko did. P.S. beat error too high.

@spidiq8 2 жыл бұрын

Because there are a great many movements where you cannot find the data to find the lift angle. Hence the title how to calculate on an 'unknown' movement. This video is about calculating lift angle and was on a convenient to hand movement, not about the beat error.
