I picked up a Speedy FOIS a couple of month's back before they were discontinued. I love the watch! My question is I recently noticed that the hour sub register alignment seems slightly off. I took a picture of it at the 3 hour mark, but each hour seems to have this degree of variance.

Is this normal for the 1861 movement? Do others notice this on their watches as well?

 

It’s normal. It’s never been a particularly accurate hour counter, as @Archer explains here: https://omegaforums.net/threads/the-mysterious-speedmaster-hour-counter.125632/
