Accuracy during flight

[Giovannibravo]

Today, I flew about 5 hours. Lost 5 minutes on my 124060. Is it normal to lose that much time to the variation in air pressure during a flight?

[Andad]

No.

[georgew]

A follow up question would be: what has been (is) the accuracy during a normal (non-travel) day?

[SS Oyster]

The mainspring (if properly wound) does not count on gravity to keep good time. Flying at less than 36,000 feet provides nearly the same gravitational force anyway, so I don’t see how flying has anything to do with your watch’s ability to keep accurate time.

Did you change time zones?

Definitely not normal.

Were you traveling near the speed of light?

Heh, exactly my first thought!

Oh no not only do we have to worry about low amplitude, but now high altitude lolololol

We need a new thread on this, probably in the tech forum.

Fly fast enough and you certainly would!

Did you go through magnetometer in security? My Rolex has no issues with one but my PP goes crazy even when I use a particular laptop.

Shouldn't matter, cabin is pressurized.

Right.

Airliners typically maintain a cabin pressure of around 8,000 feet MSL flying at the airplane's service ceiling (usually around 40,000 feet MSL). I fly an unpressurized single engine airplane cross-country at altitudes up to 10,000 feet without supplemental oxygen and my watches (usually a GMT II) maintain the same accuracy as when at sea level.

So no, it's not normal to lose time due to flying.

Another 32xx story.

LOL! My exact thoughts!

I fly over 130 hours a month as a commercial airline pilot. My BLRO is spot-on. Just like on the ground.

Boy your arms must get tired!





Yeah… OK, I’m a Dorklehead

The better question is how are you immune to FAR 117 flight and duty limitations? (not "calling you out", just generally curious)

I could see credit 130 with premium trips or overrides, but not actual flight hours.

If so, you're a madman! I'm done at 80 hours, I leave the airport like Fred Flinstone left the quarry.

[AF_Rob]

Just a thought... When traveling and changing time, I have on occasion accidentally set the watch either 1 hour or 5 minutes fast or slow not paying attention.

[Giovannibravo]

Could be the case? Will monitor it over the next few days. Hopefully not a 32XX issues.

Did you manually adjust the time?

Even the worst 32xx issues aren't 1 minute per hour (without being aware prior)

This has also happened to me. Most likely the case here

I've done that several times. I look at my digital "Atomic" clock, then in my mind am thinking i.e. "52" and count two minute hash marks past the 50 mark. Then realize hours later that I went two hash marks past "55". The seconds are still spot on...

[WatchGuy1966]

Everyday, without fail, I say to myself "I thought I'd heard it all on here before"

[996marty]

Hopefully it’s just a one off but definitely shouldn’t be doing that

[Rolexken]

Whatever the cause it won’t be the altitude or the flight.

Most probably a owner error as flying in a airplane in will not effect a watch.
