What the heck did I buy: monocoque Seamaster with arrowhead markers?

I have had incredible success using buyee as well for the Japanese market only items but have also encountered some problems with customs when they refuse to export certain items and the package has been consolidated for shipping to the U.S. I had to eat s few hundred dollars on a tool and bracelet over a leather strap that was not listed properly. They dispose of the package at the warehouse if you select the wrong way to deliver. Other than that I love Buyee 🤣
