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”

+21 pts“I wouldn’t mind owning a Speedmaster, but I wouldn’t pay half of what they want for them. It’s insanely overpriced.”

What Redditors Say
Best praise vs top criticism for Casio G-Shock
Best Praise
+137 pts“Help a guy out, anyone? I was in service for 12 years. Started as a tank driver, and worked my way up to 1SGT and ran a company of 140 troops. Never in my career have I ever used a mechanical watch out in the field. It’s mostly G-shocks. Crossed paths with Infantry and SF, and they mostly wore Garmin. And still, if there’s going to be a mission that ran several days…G-shock is still the way to go. So……my question is why and what’s the use?”
r/Watches
ViewTop Criticism
+154 pts“I like it a lot, really nice hybrid between design languages. Problem is G-Shock seems to treat their all steel watches as a study as to how expensive they can make a watch and still have people pay.”
