That's pretty typical, most of my Speedmasters show a similar discrepancy. As long as it doesn't impair the correct reading of elapsed time I can't get excited.
Agreed.
Mine is a little like that as well.
With the registers re-set to their starting position, the Hour register is ahead a fraction(maybe a half a line thickness or more). But you have to look through the Crystal on a shallow angle from the 6 o'clock position to line it all up enough to notice.
So there's that with mine to start with but it's a little hard to gauge because of the tail of the Tachymeter hand obscuring the view. Then when I press the button to start the Tachymeter it seems like the Hour register hand jumps ahead a fraction further but that could be a figment of my imagination when all things are considered.
This is how it all starts out so it's ahead but it's still a very good guide and it's not that far out that it's ambiguous as to how many hours have been counted off.
I have found a remedy of sorts just mucking around with it where the hour register reads much more accurately(for the want of a better expression) for anyone who is interested.
I simply run the Chronograph for an extended period of time. As the hours are counted off, the advanced nature of the Hour register pointer comes back into synch with the actual marks on the register to the point that it's spot on over time.
Each and every time I do it mucking around like that and letting it run, it seems to get a little better

In fairly recent times and responding to another question in this regard, Al has given us a great explanation as to how the hour register works when it's running off the mechanism.
If I understand correctly, the Hour register is driven by a very simple frictional interface so if I'm right about that, it would explain why things improve as the hours tick by if there's a touch of slippage on the drive wheel/wheels.
It's still a workable guide as it's only recording hours
😉
In summary, when I run mine for an extended period(a good number of hours) everything comes into proper synch.
Every time I do it, it seems to get a little better

I urge others who are experiencing the same phenomenon to try it and give us some feedback
