What company/companies make perpetual motion watches? And how are they?

Not talking about the Citizen Eco-drive, which is powered by light.

Or maybe I'm terrible mistaken about this whole subject, I know very little about watches.

Fill me in?

Thanks.
 
You mean an automatic watch? Like a Rolex/etc?

The ones that are powered by the movement of the user?

Indeed, i AM mistaken, on second thought.

Perpetual motion is a property that is unachievable.
Check it out, though:

What I mean, is the "kinetic" watches. I.E., the Seiko kinetic watch line.

Does anyone else make "kinetically" charged watches?

Thanks, sorry for the mixup.
 
Ok, after some searching I answered my own question, sort of.

I'm after an automatic watch.

Does any company make an automatic watch that features a luminous display? Not just glowing hands/numbers. A luminous background, like indiglos, etc. I can't find any, and I'm assuming they are too power-consuming for self-winding technology. Prove me wrong?
 
A self winding (mechanical automatic) watch has no battery to power a light. At least none that I know of.

no light.... damn.


Many thanks for the links and input. Too little, too late, however- I picked up a seiko last night. :)

Take care guys.
 
My Citizen is an Eco Drive Duo. It uses both motion and light to power it.
 
In the Nov. 2002 issue of International Wristwatch magazine, issue No. 61, starting on page 78, is an article. It details the creation of the EWS [Eternal Winding System], by one Steven Phillips, a watchmaker out of Connecticut, USA.

Basically, the watch movement is designed using "...a temperature-reactive bimetallic coil...and...a system to capture the angular deflection (circular motion of the coil when expanding and contracting) and transfer that motion into a mainspring..." page 82.

So, in short, the watch uses temperature changes to keep the mainspring wound. Theoretically, if you take off the watch and leave it on a table, then come back two weeks later, or more, it would still be keeping near quartz accurate time. As long as it's in an environment where the temp. fluctuates, the watch will keep itself wound indefinitely, barring any kind of mechanical failure. :D Truly, the first self-winding watch.

You can check here, at the Poljot Forum, and at Russian Souvenirs for good quality, reasonably priced mechanical watches, both automatic and hand-wound.

BTW- Anybody wanna buy me one for my b'day? :p
 
Good Evening All-

Everything you've always wanted to know about automatic watches can be found at TimeZone with a few clicks of your mouse.

Not a flame, but does it seem that folks don't use the SEARCH capability of this discussion forum? Some of the same topics seem to repeat themselves over and over. Holy Cow! Maybe I'm just cranky in my old age. :cool:
