Best praise vs top criticism for Omega Seamaster Diver 300M

Yes. Despite being beautiful pieces, Omega’s sport watches are first, and foremost, tool watches. They are meant to be used. My Speedmaster and Seamaster both get regular use and get banged up a little. I wear them to the range, the gym, hiking, swimming (not the Speedy), etc. They’ve both got plenty of scratches. In fact, I forgot to take the Seamaster off while climbing one time and got a particularly nasty scratch on the clasp.

Best praise vs top criticism for Longines HydroConquest

Best Praise

Buy what you really like and want to wear the most. Forget about building a collection, filling a box with different types, brands, colors, etc. Just buy what you want the most. You really like the Hydroconquest? Buy it. Wear it. Don’t cheap out because you’re saving up for another watch. If you’re doing that, you’re buying watches for the sake of getting more watches or building a collection. Let the collection form organically. I’m sure you’ll buy a watch or two here and there that you liked at first but then got tired of it, but it’s all good. You can sell them or give them away. Buying stuff to fit a collection rather than buying what you truly want is the easiest way to get watches you quickly fall out of love with.
