Taking a couple of shots of the newie today and thought I'd do a quich comparison. This shows the 600 T-Graph and 750T and the SD. The Rolex is actually quite small. I remember reading about how people thought it was bigger and heavier than the Submariner. Well compared to the 750T case, it is a wimp. It is surprising how un-noticable it is compared to the big orange dinner plate dial of the 750T and the T-Graph.
Interestingly enough, I have seen it written that the SD dial is about 1mm less than the diameter of the Submariner.
I tried a couple of shots comparing the SD against the 600T Sharkhunter. The sizes are much more comparable but all the photos were crap because I couldn't get the lighting right for the domed crystal on the 600T. I'll try again later.
