Jkay Posted July 23, 2009 Report Share Posted July 23, 2009 A ferris wheel with free gondolas has no rotation at the watch. Unless the gondolas are fixed and not free. Have you ever found yourself upside down on a ferris wheel? nope. Quote Link to comment Share on other sites More sharing options...

Have you ever found yourself upside down on a ferris wheel? nope. It was as concern but I thought the gondolas would rock a bit and that it would be sufficient to wind the movements. What about the knife thrower's assistant's wheel configuration? http://ny-image1.etsy.com/il_430xN.63886649.jpg Quote Link to comment Share on other sites More sharing options...
chronoluvvv Posted July 23, 2009 Report Share Posted July 23, 2009 so basically i can tape my watches to my kid's big wheel and they'll wind as he pedals along Quote Link to comment Share on other sites More sharing options...
Packard Posted July 23, 2009 Author Report Share Posted July 23, 2009 so basically i can tape my watches to my kid's big wheel and they'll wind as he pedals along Basically a picture frame on the wall with the watch so that the face is out. The entire watch rotates about 1 x per minute (using a clock motor for a drive train). The rotation is not the same as you would see in a normal watchwinder. I still think that the "lulabye" idea (gentle rocking from side to side) is the most movement friendly of the bunch. How many "rocks" per minute would be satisfactory?

Neuuubeh Posted July 23, 2009 Report Share Posted July 23, 2009 (edited) How many "rocks" per minute would be satisfactory? Keep in mind the winding mechanism isnt perfect - depending on the movement, the rotor has to make a certain amount of movement before even engaging the gears and transfering power to the mainspring. I don't really remember the numbers, and its very dependent on the exact movement.. A link for you about different winders.

Guest techlogik Posted July 24, 2009 Report Share Posted July 24, 2009 I see the point of that article, but it completely ignores the fact that a watch on your arm has more issues of torque and movement then a winder does. Once a watch is wound on your wrist, you keep moving your arms all day right? So the same applies to wearing a wound watch all day and continually putting stresses on it.

Ronin Posted July 24, 2009 Report Share Posted July 24, 2009 Wow, that article nearly put me to sleep. Good points, but, the abuse a watch takes while worn I would say puts greater stresses on it. Think herky-jerky movements like while driving, or bumping into someone in a crowded room. Hell, ever Jog with an automatic, or ride a motorcycle. Also, his argument about the fuzzy logic winders that stop the watch for 1/2 a day possibly upside down, or crown up/down.... So? Over time it averages itself out. Right now, my winder is stopped with the watches crown down. Last night, they were in a normal position. Think of this as pseudo-COSC testing. I think the 'randomness' of my AceTimer fuzzy logic system gives me a good read on the movements accuracy. YMMV, Quote Link to comment Share on other sites More sharing options...
Neuuubeh Posted July 25, 2009 Report Share Posted July 25, 2009 I just posted that link because there was some different ideas of watch winders (so the OP could decide on which to build ;o ), didn't pay much attention to the details lol . Glad you guys read it tho ! Quote Link to comment Share on other sites More sharing options...
Packard Posted July 27, 2009 Author Report Share Posted July 27, 2009 What would happen to a watch if I wore it while hitting the heavy bag in the gym? Would it wind or self-destruct? Quote Link to comment Share on other sites More sharing options...
JohnDorian Posted July 27, 2009 Report Share Posted July 27, 2009 Are his watch movements made of cotton balls and archival paper or something? Acetimers are very inexpensive and effective, not sure why you would get anything else unless you're willing to splurge on Orbita. Quote Link to comment Share on other sites More sharing options...
Guest avitt Posted July 27, 2009 Report Share Posted July 27, 2009 How about buying one of these cheap eBay winder/testers, and adapting it for your own purposes? Quote Link to comment Share on other sites More sharing options...
