I don't begrudge people who prefer smaller watches, including divers. BUT I BEGRUDGE WHOLEHEARTEDLY people who espouse no watches should be bigger than 40mm.
That is what pisses me off about some in "the smaller is better" crowd. The zealotry and absolutism some espouse is ridiculous. This seems mostly found amongst the newbies who want to prove their WIS bona fides by advocating extreme positions on watch sizes bc it seems to be trendy.
Anyway, I can wear anything up to 50mm provided the lugs are short. This 48mm cushion case Invicta is a good example.
But my ideal diver range is 40mm to 46mm.
I just got this Aragon Hercules GMT bc I wanted a cheaper "caller" GMT. It is 43mm, but 14mm thick. t wears larger as the tungsten bezel is somewhat narrow making the dial opening larger ( a key variable in how big/small a watch wears IMHO).
The 14mm case thickness was not a selling point for me, but the Soprod Swiss GMT movement and tungsten bezel were with a sales price of $410 were so I accepted the case thickness.
