DIY Watch Winder

[gng]

This is for the brave and daring...

As mentioned in my DIY postings, I'm sharing alternative ways how you can DIY your own horology-related products. If you are unsure to built one yourslef, its best to purchase from several people who sells those items here.

Anyway, this circuit is very close to those AC Winders you find in the market except this one is able to adjust both the rotation and stoppage times.

Warning:-
1) This circuit involves HIGH VOLTAGES and I advice you not attempt it if unsure.
2) For those who know electronics, you can substitute RV1 & RV2 with a fixed resistor once you found the desired value. That is, the rotation & rest times.



For the DC version, I've already done it much earlier in my blog.

Have fun guys!

where can get the AC ?

Nice.. Thxs

Hello Ten10. Thanks for sharing and its good to know you have also provided the specs. My winder conked out some time ago and I never bothered to try to fix it. Your post has inspired my tinkering itch. Is the motor rating of 230V 8RPM good for a 2 watch winder?
Mine is a 2-watch winder and there is only one motor driving it.

Also any recommendation where I can buy such a Mabuchi motor?

The schematic I’ve shown is the actual circuit for this…

This is a 230VAC winder but internally has a step-down transformer that has a 12V output. This means the motor is still an AC type.

I’ve also reviewed this winder (below) and found a slight modification to the circuitry from the one I’ve listed. The general idea is employed.


Its not as simple as just picking any motor to use for a watch winder. Considerations are needed to factor in the anglular momentum, battery life, torgue, etc. etc.

Do check out my blog articles in the DIY Section for more information on watch winders...or come for the Anniversary Dinner to speak with me personally.

Peace out...!

very hard to understand ....

Wah very chim wor.
Every morning i push my grandmother wheelchair can i put my watch on the wheel?
Can winding the watch right? Not many turn around the void deck only.

If I have auto watch I hand on my toilet door.
My house many poeple use toilet open door close door sure winding my watch. LOL.

OMG! Pls dont hang your watch there on your door.

Watchwinders have a particular angle of wind (cosine rule) to have effect on the watch rotor. Its not as simple as just swinging it.

French Fries, hope you have some time to read the blog about watch winders HERE!

cheers.

Aiyo...watch swing does not mean rotor bridge swing .

very chim

Ooi bro, dun liddat leh... come for the gtg I can un-chim for you

DIY stuffs may have some reliability issue...so may not worth to put a rollie for testing.

I would definitely not show the actual schematics on how I built my commercial models...

These DIY stuffs merely shows the principles of a watch winder.

BTW, the schematics shown here are cross-referenced from one of the circuits of another commercial watch winder. Perhaps some of you already own one of these...

Good schematic - for those electrical spare parts maybe attach a list so that they can source. otherwise, can sometimes ask chip companies for "samples"
