I got this email a couple of days ago. I wouldn't worry.
Dear Customer,
I wanted to let you know that our production run of 1962 chronographs has been held for inspection and clearance by customs authorities in Europe. Because of this delay, we will not be able to meet our commitment to ship your order to you by August 1.
I am sorry about this delay, We are doing everything we can to resolve the issue as quickly as possible.
.
At this point, our best estimate is that your watch will ship to you in 5-10 days. As soon as we know the schedule, we will send you new tracking information.
We appreciate your patience with this delay. As always, you may cancel your order anytime and receive a full refund by contacting us at support@danhenrywatches.com.
