Best Praise
+186 pts“Speedmaster because the ingenieur is grossly overpriced for what it is. Honestly the watch should either be 30% cheaper or have microadjustments in the bracelet and a see through caseback with a decorated movement, because at this moment it feels like a IWC Mark watch with 2x the price”

What Redditors Say
Best praise vs top criticism for Omega Seamaster Diver 300M
Best Praise
+8 pts“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.”
