Rolex in flight

[PACEVIPER]

Should you open the crown when ascending or descending in a non preasurized aircraft.......Thanks Jimmy

I've done it numerous times. You do know that even in pressurized aircraft the cabin altitude does not stay at sea level right?

Except if the aircraft sinks below 100 M, you should screw the crown

Yes. that's why your ears still pop.

Pressurised or non pressurised makes no difference.

The pressure differential in a pressurised aircraft equates to around 8000ft for cruise. Non pressurised aircraft fly 10,000ft and below, usually far below as most recreational pilots prefer to stay below the clouds.

As for opening the crown? A trip lock crown is still waterproof at recreational dive limits (as evidenced by the number of divers who have left their crowns unscrewed) and the pressure differential on your watch seals 40m under water is far greater than that at 10,000ft in the air.

Feel free to adjust your watch in an aircraft. People do it all the time.

Are you asking whether you should or whether you can? I think people are answering that you can, not whether you should.

I have been told that you should when ascending and descending to equalize the interior of the wash. Just want to know if it's an old Rolex tale or if there is some validity to it

It is complete bunk. No need to do any such thing. You can leave it alone or set it in-flight; your watch will not care.

your watch can handle way more pressure then you can no need at all to do anything of the sort.

Flying changes the cabin pressure 1/2 atm at cruise, less than 5m of water depth equivalent. Watch wont even notice

When I countered with a similar statement, I was told the watch was designed for external pressure pressing in. Not internal pressure trying to escape.

Correct.

And over the last thirty years of Rolex ownership I must have set my watch in flight many hundreds of times.

Helium escape valves are set for over 1 bar normally so the watch is expected to be able to easily take -0.5 bar internally

I've flown over a million miles over the last 15 years on commercial aircraft of varying sizes all over the world. I have adjusted my watch in flight countless times. If there was any ill effect, it certainly never materialized in any meaningful way that I could detect.

Same here. I have adjusted and not adjusted. Nothing has ever gone wrong.

Pan Am pilots didn't seem to have any problems with their GMTs.

^ This also neither of the countless astronauts who've gone in to space

Myself and the many other Rolex wearers who fly professionally have subjected our watches to countless pressure change cycles. It doesn't hurt the watch at all. Even a rapid decompression at cruising altitudes doesn't affect them.

Pretty sure a Rolex can withstand the rigors of flight. If not, I'm looking for a new brand Monday morning.
