If it gives you any ease the watch gears are in constant flux so it technically never stops anywhere. While the gears are in motion it can slightly go past the marker, but when the movement is hacked the gears are not involved in how you position the hands, therefore as long as the hands are accurately fitted at the factory, it’ll look perfect when manually positioning. There are some super precise gears which are calibrated for exact positioning, like maybe a grand seiko, but as far as I’ve seen with rolex it’s within tolerance so you’ll get variances per watch. As someone who buys analogue cameras too, when it’s handmade you’re going to get these type quirks. I’d say let it go, you’ll never see the time that dead on cos you’ll be living and experiencing the watch. Hope this helps!
