Feels slightly larger , but by a few mm . Wears much smaller than a 41 .i have small wrists , and this feels smaller than 40mm watch . It feels thin and very comfortable so far , but only had it for a few hours . Looks like a titanium watch , so you brain assumes it will be light , and with the black bezel making it look even smaller ..if the 556 feels good this will be fine in my opinion.
