Best Praise

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

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