How durable is the bezel on explorer 2

[Golden Ellipse]

It will show more wear than the Sub, since the Sub uses a crenelated bezel whereas the Explorer is smooth (with a polished edge to boot). Hence aesthetically, the Explorer is somewhat more "delicate." Mechanically however the Explorer's bezel will survive a hard edge-on knock much much better than any rotating bezel, whether aluminum or ceramic insert, since the entire assembly is permanently connected. The Sub's bezel is dynamically connected using springs, ratchet, and retaining plate connections. Therefore the answer to your question really depends on whether you're interested in appearance or mechanical robustness.
