Nice quick review. I've had mine for a while and have been wearing it on a NATO. I just started wearing it on the bracelet and can't keep it on while working. It hurts and I have it on so loose it will spin on my wrist. It might be back on the NATO soon!
Sounds like it's time for a service. If yours is a new watch then talk to the seller. +40 is outside specs. The watches i own with this movement fall between -15 and +5 Good luck and thanks for watching/commenting
