I always wondered about this. It inspired me to do my own experiment - on a 7S26. From completely dead, 10 seconds of shaking the watch (the "seiko shuffle") and then setting it down allowed it to run for 1 hour, 39 minutes, ~35 seconds. So 40 hours of power can be charged with about 4 minutes of shaking.
No, not exactly. Winding force isn't linear. Ever wound up a toy, music box, etc? It always gets harder to wind the more wound the spring is. Same for automatic watches. That last 1/4 or so of power reserve will definitely take longer to build than when the mainspring is more unwound down at the bottom of the reserve.
hey, just saying, not really! i left my seiko 5 (snkl23j1) with a 7S26 movt dead, vigorous shaking for near a min only allow it to run for two rounds on the second hand.....the hairspring ran super slowly, but after an intense workout (dance) for near 30 min, the watch ran normally for 3h
In my experience, an NH35 (42h power reserve, one of the most common movements currently) needs approximately 35 winds from zero to full, and around 20/day if you want to keep it running when it's just lying around. The automatic winding is very efficient though, I feel like 45 minutes of (casual but determined) walking per day fills up more than 24h power reserve.
Also, the mainspring gets harder to wind as the power reserve goes up and it gets closer and closer to fully wound. That means getting into a higher power reserve status takes even more time.
Keep in mind that the spring is a spring. The tighter, you wind, it, the more force it is going to require to wind it. So, with automatic watches, they tend to win, super smoothly, and quickly in the first third of their wine, and then the rest of it is a lot harder and if it’s an automatic will take longer. The weight just is it not able to put out enough for us to make the same large changes that you would get at low reserve
Thought I've read SII movements need 50ish turns when fully unwinded. The new Orient caliber the F6b22 needs also about 32 winds for a full reserve. Nice to see pracitce example papers are anyway only guidance. I do normally wind until I feel that it got some resistance so I guess it's full then.
I assume the font in the thumbnail is a reference to Iron Maiden's "Powerslave", isn't it? Very interesting video. I often manually wind my autos, I was curious to know how much winding is enough. Your experiment provides a useful rough estimate.
good video, thanks for doing that, I've always been curious about how much winding is enough across different calibers. Hey I don't suppose you could do this with an SKX007 or something with a 7S26 caliber? I'd be very interested to see how to get that movement fully wound or if it's even possible, cheers
@@the1010watchclub I have one, the SKX, and even though I've pimped it out with a great bracelet and love the looks, I'm rarely reaching for it unless I'm planning on wearing it on consecutive days....that never happens ;-) It'd be cool to know what the best techniques are for getting that sucker's power reserve up to it's supposed 40 hours, or if that's even possible, cheers
Only by identifying what the movement is and looking it up. Also you can try spinning the rotor. If it spins super-fast in one direction, it’s uni-directional.
@@the1010watchclub - Oh! When I do that the winding stops like it fully wound but if I immidately shake it a few times I may continue winding toward full wind !
It still rotates, but it doesn’t break the mainspring. Automatic watches connect the spring to the barrel using an application of braking grease rather than a fixed connection. So it just moves the barrel around the spring.
I posted a video like this 6 years ago, was always hoping someone would take the time to go deeper (With much better production value), Awesome job bro! I assumed from my own experimentation much like yours (1:49) after you get past 15 or so the spring has more and more tension it has to work against, so it "charges" slower. It usually takes a couple of days wearing or lots of manual labour throughout the day to get fully charged. I think this is why people complain about lower then advertised Power Reserve complaints from watches. Also don't forget High beat will use more then a lower BPS movement so 15 on yours is probably like 20 on my Orient "Seiko shuffle" test (Power reserve indicator) Orient Polaris GMT ua-cam.com/video/5LWklQuaHZQ/v-deo.html

Love it! That’s commitment. Definitely better than the unidirectional rotor

thanks for the info 👍 the bi-directional winding rotor on the NH series is great
Also, the mainspring gets harder to wind as the power reserve goes up and it gets closer and closer to fully wound. That means getting into a higher power reserve status takes even more time.
Thank you for the video, I was looking for this answer that how much movement to wind it automaticly in daily life. This video gives idea to me
🤘🏼
Good on you for voting!

I need to try this with my Seiko 6r21...
Thanks good stuff!
You should! Let me know what you find out

Hey man, this is really informative. Plus 1 to your subscribers.
Thank you! Welcome to the channel
Very informative video thanks ,
You have 999 subscribers! Great video as always - keep it up!
Thank you!! We just tipped over 1K!

The same experiment with a watch winder case would be helpful.

That's a lovely watch! Great video.
Thank you!
Love those Zeppelin watches ..
Same! Just had a stager compliment it the other day too
thanks for this one!

Good idea, I have one or ten watches with a 7s26 in the back at the moment, they multiply like rabbits!

Look at that Spector in the background though 😍
🤘🏼🤘🏼
wow thanks for this video man I learned a lot
Thanks for watching!
Nice watch!
One of my favorites!
😍👍🏻nice informative video🤤
Thanks for watching!
Thanks, I wonder why my watch wasn't winding when I spun the auto Winder. I didn't know it was omnidirectional.
Hamilton Khaki Mechanical 34 with the ETA 2801-1 manual movement is about 31 turns to full power as well... Interesting.
🤔
Thanks for the video. Is there any way to find out if the rotor is unidirectional or bidirectional by looking at the glass back of the movement?
Only by identifying what the movement is and looking it up. Also you can try spinning the rotor. If it spins super-fast in one direction, it’s uni-directional.
York that d with you ür led hand
That gives a fast charge
A bidirectional experiment would be cool too.
Does vigorously shaking the watch wind the watch faster to full reserve of power than winding ?
My guess would be that winding is the fastest way
@@the1010watchclub - Oh! When I do that the winding stops like it fully wound but if I immidately shake it a few times I may continue winding toward full wind !
When the PR is full and we still wear the watch on the wrist, Does the rotor stop rotating or still rotate and break the mainspring?
It still rotates, but it doesn’t break the mainspring. Automatic watches connect the spring to the barrel using an application of braking grease rather than a fixed connection. So it just moves the barrel around the spring.
You wore your watch below the wrist bone. I wonder if the results would be different for those, like me, who wear theirs above the wrist bone.
Time for another experiment!
I put mine in with the washing as I'm old and not very active, but now it doesn't work at all , so much for waterproof, tut.
Shaking the sieko automatic watch does wind mainspring?
Yes as long as it’s automatic
My Orient watch manual says 30 manual winds will get the watch to maximum power.

what a coincidence i just watched your video before coming. to this one
Is it normal to be able to manually wind automatic watches?
Yes, the majority of automatic watches (especially above $300) have a hand-winding capability
Who sell this in USA ?
I found this one on eBay but Long Island Watch sells the brand too
42 movements to fully wind it
Ride a Harley Davidson and it will always be topped off 👍👍🇺🇸
😂
32 not 31
You did 32 turns... nice bait :) !
