My sarb035 has uneven marks. The minute marks are clearly made in a separate step from the subminute marks, but they're also inconsistently spaced between (different amounts of space left and right of the minute mark, but it's different for each minute too). It's almost like there's somebody manually turning a machine and eyeballing the angle. That might in fact be true... The same is true of every high-res picture of a sarb033 and 035 I've seen. I have a vague memory you can see chapter ring problems with some more expensive models, but it looks like the new 41mm Presage has a perfect chapter ring.
My rule at this point is to avoid Seiko chapter rings, unless it's a Grand Seiko or I can see it in-store.
I'd bet Casio has perfect chapter rings at every price.
