Does a reply from a Scotsman count?
Try Royal Mail Airsure, insured separately via ParcelPro
Its pretty easy and relatively inexpensive.

: I just found a new Heuer from a English gentleman.
: When it came to shipping, I asked him to ship me the watch (to
: France) using a fully insured service.
: This gentleman is not used to ship items worldwide and lives in the
: countryside.
: He made some requests to Royal Mail, Parcelforce and DHL.
: He reports me none of them offers fully insured services for
: watches.
: Would any English gentleman from the community have a tip to have
: the watch shipped fully insured ?

: Thank you,

: Laurent
