Shipping from mainland China is generally very very good. If it gets held up in a facility in the US, then so be it. You never know what is going on there. One simple incident in that 'particular' facility can cause delays sometimes. For example, they could have for instance received a shipment of tarantula spiders, so everything stops for more inspections. It happens sometimes. But nothing really serious to worry about. Maybe the customs guy just likes to fondle your watch for a few more days !! Patience my friends !!
