The guality of this build is amazing and its powerd by the 6r15 movement one of the best in this price range a rock solid workhorse in a beautifully designed case and the 20 mm band is just fine great design as far as Im concerned If you're thinking about this watch just pull the trigger you won't regret it or keep contemplating and pay double in the future. Update I have this watch one month now after regulating twice its keeping perfect time if I would have never opened it +3spd is where it would have settled in from the box love this watch everything about it
