Personally, I'm still trying to get used to the look of the 5170J. The dial feels a bit larger, despite the 39,4mm diameter. I suspect this is due to the conical bezel and also the white opaline dial that makes it look larger versus say, a black dial. I do however like the dial layout of Roman (XII, VI) and stick markers. The only complain is the empty ring space around the 7-9 o'clock.
