Hey guys,

I recently bought my first Speedy - A 3570 Mitsukoshi mod and realized that it has been running since my last full wind 68hrs ago. Is this normal? The watch was from 2003 and has not been serviced before. Perhaps it's due for one? It has lost 19s in 68hrs.

 

That must be the new perpetual motion 1861 movement

 

You sure you didnt wind it in your sleep?

 

I'm no expert but I think it has some problems

 

I don't wear it to sleep.

 

wow.....I think a full wind on 1861 movement will run something like 42 hours.

 

Its 48hrs actually. Which means mine has been running for 20hrs way past it's specified PR!

 

Beautiful watch. Not sure about the other issue.

 

Is it really a issue if its running well past the PR, since time keeping is pretty within spec range.

 

I think you have an extra long mainspring in that mainspring barrel!!!

 

That's pretty impressive! How far did you wind it to start with? Did you feel any force when you stopped winding?

 

My 321 Ed White runs for 60 hours, I thought it was cool but maybe it isn't ?

 

I think that's about right for an Ed White?

 

Do you keep it by your bedside? You might be winding it in the middle of the night without knowing it. You might want to use one of those night vision cameras to see what's going on.

 

Haha that's pretty creepy! I keep the watch in a watch box that's locked. There's no way i will wind it while asleep.

 

Yup, i felt that there's something that is stopping me from winding once i've winded like around 30-40 turns. The crown feels tighter with every wind.

 

It does sound odd. I'd say it's probably worth getting someone to check it over but might just be worth keeping an eye on it and seeing how it runs now it's in regular use.

 

Well it was just serviced so I'm going to let it as is. Better have a bit more power reserve than a bit less !

 

Why would an Ed White have a higher power reserve than a more modern Speedmaster?
