Is this watch come with the COSC cert? I think their in-house has no COSC...
Without COSC I think 20 sec is not as bad... How long have you wear your watch? If you jut bought new maybe let it sit for few months first before you time again?
Don't think the warranty cover this unless it come with the COSC cert and it's not running within range then probably you can send back... Also, I remember their in house movement has been time before ship out.. Check the warranty book and see... Pam233 is not COSC but it has been adjust to COSC before ship out and the timing stated on the warranty book.. Not sure about the P9000 series movement...
