Hello everyone,I noticed my DW-9052 has plastic buttons. Does this make the watch mud-resistant like a G-9000? Also, is a G-9000 bezel truly mud-resistant with the gaps around the crystal and case back? In other words is this more about marketing than functionality? I ask because my DW5600e, DW6900, and DW9052 have had no issues with sand and mud or oil thus far.
