space travel

[sws999]

If I were to travel in a space ship, with zero gravity, would my Sub wind up, or would it get to the end of its power reserve and just stop?

Centripetal force still applies, so if you were to 'flick' your wrist the rotor would turn. If you were to simply turn your arm, the rotor would not fall to the lowest point since there is no lowest point in space. In short, you'd have to be swinging your arms around a great deal. It would be an inefficient choice of watch for your space travels.

what about the watch the moon astronauts wore, the Omegas?

For every action there is an equal but opposite reaction. The laws still apply in micro gravity.

The Speedy is a manual wind

[Watchmutt]

It will work since the rotor will under inertia from movement.

Have you got your ticket?

[Apdl]

I think this is one of the reasons NASA went with the Manual wind speedy
But, many American astronauts have worn a GMT in space and one has been on the moon(recently sold at auction) with no issues.

[brkanand]

No worries. Forget the sub and wait for the next Rolex model - Space-Dweller!

Maybe that and the fact that the automatic wind Daytona wasn't available back then.


In 1962, Nasa purchased 2 copies each of Elgin, Benrus, Hamilton, Mido, Piccard, Omega, Bulova, Rolex, Longine and Gruen. Of theses only 3 where selected for the comparative evaluation testing: Longines (13 ZN), Omega (321) and Rolex (Valjoux 72).

In 1965, the testing was done:

The Omega Speedmaster gained 21 minutes during the decompression test and lost 15 minutes during the acceleration test , and the luminescence of the dial was lost during the test

The Rolex Daytona stopped running on two occasions during the relative humidity test and during the high pressure test when the sweep second hand warped and pressed against the other hands.

The Longine Wittnauer crystal warped and disengaged during the high pressure test , same fault occured during the decompression test.


The Omega Speedmaster was selected.

I don't have a ticket, but yesterday I had a bad accident with a live electric cable on which I was working. I thought the mains was off but it had been incorrectly wired by someone in the past . I received a very serious electric shock which put me in hospital for a day, and I have got some very bad burns on my left hand. the plastic surgeon said I may even lose the tips of two of my fingers! Anyway, the point of this diatribe is to say that at the moment I am so drugged up on painkillers that I feel completely "spaced out", which got me thinking about space travel.
Still, at least my watch didn't suffer any misfortune, and after about 10 seconds of me being connected to 240 volts of mains is still ticking away quite merrily.

No. Your Sub would not wind. You would have to manually wind it.

Dang, sorry to hear that! Hope you don't lose your fingertips and make a complete recovery!

[Sky-Dweller]

Sorry to hear that...

This is shocking! (sorry, couldn't resist, best wishes for a speedy recovery!).

Actually it would as stated on a previous post. Centrifugal forces.

There is an interesting podcast on Jakes Rolex Blog with an ex Rolex employee that was around in the sixties. His job was to mingle with celebrities and offer them Rolex in exchange for advertisement time. He also had a part in the invention of the Gas Escape Valve and Sea-Dweller.

In this interview he makes a comment that rumor in the industry was that Omega paid NASA big bucks to use the Speedmaster in space once they found out they were testing watches for astronauts. Not sure if this is true but the tight relationship they have to this day makes me think it's possible. I went to Johnson Space Center a few months ago and Omega does a great job of advertising the Speedmaster all over the place with huge clocks.

I want to wish you a Speedy recovery!

.

great info, I have wondered how the daytona fared in the tests as we have all heard about the rigorous testing the moonwatch has gone through

[mjclark32]

Hope you recover well!

[Ditch]

All the best Steve! Wishing you a full recovery. Things could have so easily turned out much worse.

To expand on my first answer, if your watch were on a watch winder in space, then it would do next to nothing to wind it, since they largely rely on gravity for the rotor to sit at the lowest point as the watch turns. Since they turn at a relatively slow speed they would not generate enough centripetal force to do the job instead.

Most winding of your watch each day is done by gravity taking the rotor to the lowest point each time you alter your position. This will not happen in space.

Some of your winding each day (during very physical activity) will be down to centripetal forces swinging the rotor round. This will still happen in space, and each of these 'swings' might even last a little longer without gravity bringing the rotor to it's lowest position.

So, if you were very active in space you might be ok. If you were pretty sedentary you would find your watch stopping. Manual winding would be more reliable.

Lets not forget that our Rolex can be manually wound as well.

Actually, it does work in space quite well, and according to one Astronaut, his GMT Master performed better in space than on Earth. Dr. Leroy Chiao flew his on every space shuttle mission he went on. He said in an interview, that it kept better time up there. Here is the link to that story:
http://rolexblog.blogspot.com/2008/0...chaio-his.html

The Omegas were manual wind watches and Nasa it's said had a question as to whether or not the Auto-Wind would work in space. This has always puzzled me....why they questioned that.

Wow Steve...sounds like you had a close call! Be careful. Hope your fingers heal. And it is amazing that your watch survived unscathed.

I heard the interview too. I believe T Walker for sure. They Paid. Still though, many a Rolex went into space, and some to the moon. Jake has done a good job bringing this to light.

He sure has. It's funny that while Omega was spending big money on advertising, the astronauts were asking T. Walker for Rolex!

Glad it wasn't worse. Get well soon.
