I forgot to mention -- The Russians had only, or possibly two, watch factories. One of them made pocket watches, the other one wris****ches, so this watch that a fellow showed me probably came from the same factory as your Vostok Amphibia. It was a pilot's stopwatch with an E6 rotary "flight computer" printed around the outside of the dial. The whole thing was dressed up to look, at a first quick shortsighted glance, like a Willy Breitling special that lived a life of hard knocks. The kicker was that the buttons for the stopwatch did nothing, and the rotary slide rule didn't rotate...It was issued to pilots. This fellow told me most of the Russian pilots craved a posting to East Germany because there they might find a good watch, made in East Germany.

You haven't experienced speed until you've stood on the drawbar
of a Farmall Model C doing ten miles an hour on a gravel road.


Hey! I've done that too.


Don't you have to be barefooted to get the full benefit?


Maybe so, but I got all the benefit I wanted with shoes on.

Yikes!

Running on body heat would give you sort of unlimited run time.


There are problems trying to utilize body heat. The worst is the lack
of an easy cold junction. In order to produce electricity, one needs
a temperature DIFFERENCE. If the body is the warm junction, where's
the cold junction? Simply heating something will work if you use a
thermocouple, but the efficiency is very low and little power will be
produced. For example, using the ambient air as a cold junction will
produce a fabulous 0.3 microwatts with this contrivance:

There are other ways that seem to be better:

Remember that you can use either junction as the cold one. You don't care
in what direction the current flows. All you need is a differential.
Using germanium you can get away with really low voltages.


The direction of the gradient isn't the issue. The absence of a gradient
(hey, everything inside my body is at body temperature!) is the problem.
Switching to a low band-gap semiconductor doesn't help.

I saw a news item once about a scheme to use sound waves to power implanted
electronics like pacemakers. I imagined the resulting headline - "He died
quietly."

Funny story if it's someone else's watch.


A) A fool and their "money" is soon parted.


I've never bought a watch that isn't now worth more than I paid for it.


I can't claim that, but looking about my old casio LCD looks to be at
least 7 times the purchase price :-)

You wore shoes "back on the farm"? It must have been winter :-)

At that time and place, barefoot was the default condition.

For people the age I was then.

:-) Yes, when I was a little fellow I ran about barefoot all summer.
and learned to step a bit carefully when walking where the chickens
had been :-)

Heh-heh. I wouldn't risk my life on it either. It costs about four times that much just to put in a new o-ring and a smear of silicon grease and put my dive watch in a pressure tank for 200m rectification. Not that I've ever dived to 200m...

If you care about such things you should read up on the case design of the Amphibia - uses the same principle as a "Super Compressor" case. Very elegant and simple and best of all (for the Russians) did not rely on precision machining.
