I generally put broken horological device for repair, or horological parts. Valuation depends on what it is. I usually ship with fairly low for reps, if I sell someone a genuine watch, it ships with full valuation and full insurance. USPS will not allow you to insure for more than the customs declaration stated, so if you declare the value at 50.00 USD, That's all you can insure it for. I believe that one thing has to be made crystal clear between buyer and seller, the watch once it leaves my possession, belongs to the buyer. He takes all risks for loss, damage, customs seizures and duty. Only after we agree to these terms will I sell and ship a watch outside the CONUS. Sent from my iPad using Tapatalk
