I did try a T3 sometime ago and would still suggest that the crystals on a Fiddy and this IWC ceramic must be 40/42mm plus which makes it look a great sized watch as well as being one. The challenge with lots of mid size watches (Rolex, Omega, AP etc. etc.) is that the size of the case is 'ok' however due to the style/size of the bezel the actual face of the watch is quite small.
Perversley I have a 44mm Panzera coming which as a size of watch is as small as I like to go, however it is literally all crystal/face so the diameter of the crystal/ dial is 40mm which I hope makes it feel ok!
