Actually, no it won't. Rolex uses a self winding mechanical movement.
Not all Rolex use the self winding movement, some have to be wound every few
days.

Even the good fakes use automatic movements.
I've never seen one like that. Those I have come across over the years had
quartz movements.

It wasn't until recently that I encountered an automatic movement in
a fake. I've seen several since. It takes a good eye to spot one.
Watchmakers are on the lookout for them, now.

You can find a decent knockoff Rolex with an automatic movement, the
correct markings, correct weight...for about $250. You'll probably get
ads for them this holiday season in your mailbox.

Thanks, but I'll stick with the real McCoy!


You know, I can't disagree.

Only the cheaper fakes would be harmed by EMP. And that's
questionable, given the steel case sheilding.




I wasn't aware of the show but I gather it's about what happens in a small
town after some sort of super-duper EMP pulse, more intense than the
Starfish prime test which couldn't even manage to burn out mass quantities
of early 60s germanium transistor radios.

Wow. An EMP pulse strong enough to destroy everything with a circuit board,
yet has no effect on everyone with a central nervous system.

I think I'll stick with domestic shortwave radio for doomsday info. It's
every bit as misinformative as TV, but far more entertaining.

Frank and Telemon, I have great respect for your knowledge and the
accurate posts you both have made over the years.

EMP could be a nothing or a very real threat.

http://www.globalsecurity.org/wmd/library/report/1988/CM2.htm

While I dislike Wiki, in this case the data agrees with that I gleaned
from
many open sources such as, but not limited to military and telecomm.
And it is in one easy to digest meal.

http://en.wikipedia.org/wiki/EMP_Pulse

I do know the US military is very concerned about EMP. I helped a
contractor
install a radio relay and I was impressed by the, even by my standards,
fanatic
steps taken to manage EMP. Double farrady cage, every i/o line was
either
optical or had multi-stage polyphaser EMP clamps. Much beyond what is
required to survive mere lightning. I am not revealing anything here
that isn't
already easy to find.

If there is interest I will post the links to some of the various
military manuals
that go into way too much detail about the risks and steps that SHALL
be taken
to mitigate EMP. This really belongs in a survivial group more then
this group.

Sorry for the 2nd post but this was too interesting to ignore.

I hope I have demonstrated that at the very least EMP or to be more
accurate,
NEMP is real and under the right, or maybe the wrong, circumstances a
major EMP event will change all our lives.

Unless some things have changed over the years,U.S.Military Aircraft are
pretested.Mounted on some stands outside with a lot of cables hooked up
to them.They are built and tested to resist EMP.No doubt U.S.Military
Tanks and Ships and Submarines and some other U.S.Military vehicles are
similarly tested too.I read about that in one of my Popular Science or
Popular Mechanics magazines back in the 1950's or 1960's.It might have
been one of my old Science and Mechanics magazines where I read about
that.For sure,it is in one of my old magazines.

I don't recall posting to this thread but my 2 cents would be that most
digital semiconductors are damaged by 1500V and greater due to
electrostatic protection. The number would be higher that that depending
on the circuits they are in. Low impedance circuits will need a higher
volts per meter to damaged them.

Generally devices that are not connected to cables will not get damaged
by EMP because the voltages developed will not be great enough to damage
the components so a radio not connected to power and an antenna would
not get damaged if they were in a metal case like the desk top radios I
own. Even plastic case radios without whip extended and not plugged into
a wall wart to the mains should be OK.

Radios connected to an antenna could have thousands of volts presented
to the the radio input and damaged it. Radios connected to the mains
could get damaged for the same reason. The EMP pulse will generate very
high voltage across a long conductor. If your radio is not not connected
to a long conductor of some sort then it should be OK.

Watches will keep working for sure. Modern car ignition systems will
probably keep working. First thing that would fail in a car would be the
radio.
