Mine ran 5-6 seconds fast for 4 or so years, until I accidentally left it on before going through an MRI. Now I’ve had it demagnetised it’s more like 2-3 seconds, but it does depend on overnight position.

My Apollo 11 50th Anniversary is averaging + 2 sec/day over the last 3 days, slightly better than my PO and my 44.25mm 329.23.44.51.06.001 Speedmaster Racing, which hover around 5 sec/day. I have two Tissot PRS516's that have similar performance, but most of my other mechanical watches are much worse

Don't know.

Not too concerned about it. I don't monitor the watches that closely.

I can wear my mid 1980s Speedmaster Professional with 861 movement for over a week' at a time when traveling and it's still within a minute. It runs slightly fast, I suppose less than 10 seconds per day. I'm not an accuracy fiend so am tickled with it.

There are about five watches here that can manage similar performance so they are all the designated "travel watch" choices.

Hey, I'm even happy with the watches that can't quite manage travel watch grade.

Another app same 1861


Those are strong results. Do you mind sharing which app you're using in the second screenshot? I've played around with a few WIN 10 apps but haven't found one that works on OSX without a VM.

I have the same watch, also 2019. Mine runs about +5 seconds a day. Placed crown up every night.

Recently got my Speedy and I find it gains about 3 seconds a day on average and 1 second per night when resting crown down. Good enough for me!
