Best Way To Ship Rolex??

[Swegin]

Am wondering if anyone has a recommendations for shipping Rolex with insurance within US?

I just tried using the USPS insured shipping program. Rates were great but it took almost 2 weeks for watch to arrive to new owner and it appeared the watch had been lost since it stopped tracking for about 7 days. USPS was almost non responsive during the process. Certainly not something I want to go through again with a sale but do want to have the insurance coverage.

Thoughts and recommendations would be most appreciated.
