Here are some pictures of my big watches. As you can tell, I'm more into sport and dive watches than higher-end "fashion" watches.
My Casio Triple Sensor PAG40 (52mm)
My Suunto Advizor (51mm)
My Citizen Eco-Zilla (50mm)
My Nike Lance4 (49mm)
My 5.11 Tactical Series Stainless HRT (47mm)
Both of my 5.11's (The original titanium is 51mm)
Add the Eco-Zilla to the mix
The S/S version of the 5:11 seems to be built very well indeed.
Easy to imitate, not so easy to innovate.
