A microscope is essential in my opinion. I started out with a tiny Leitz head, single power (had to change eyepieces to change magnification) on a boom that swung it out of the way. When I got this little Leinen I found this Olympus, about the same size as the old Leitz but switchable 1x/ 2x, so 10x 20x with 10x eyepieces. It's on a post mounted to the lathe base, swings out of the way in a second, and can be repositioned over the work "by nose" as needed haha. A lot of folks put zoom scopes on booms over the lathe; it's fine too, but I prefer this compact scope personally. -
Maybe "Skinflint Challenge" or "Tightwad Challenge" Show the before and after photos of the watch to become an official skinflint/tightwad.

Recently been working on a 7750 and the hour mechanism is the same. Essentially it is driven directly from the going barrel, but the driving wheel is friction mounted on the hour recording pinion, akin to a canon pinion. When the chrono is stopped, the little plastic part shaped like a boomerang stops the wheel moving, while the barrel continues driving the friction mounted driver wheel. If it’s periodically jumping I’d guess that it’s a lubrication problem between the driving wheel and the pinion. If it sticks it will jump the little plastic teeth in the brake showing the slight shift you’ve got in the picture. Disclaimer - I’m pretty much a novice, and have quite possibly named these parts incorrectly and got things quite wrong.

I do also have to wonder if the pushers need to be polished to that degree. I can certainly see dressing them if there are surface irregularities, but I wouldn't think that fine scratches would cause an issue. But I'm just getting to the point in my watchmaking journey of replacing jewels, so who am I to say? I did get a vintage Seitz set not too long ago and have cleaned, derusted and lightly oiled all of the pieces. I haven't yet looked under the microscope to see what the tips look like, but I'm sure that some of them need to be dressed.
