If he buys second-hand at a good price he probably won't lose too much money. As a new purchase I don't know. I guess you expect to just take the depreciation like a man. Personally, I would get an Omega Speedmaster before the Navitimer.
That hurts my head to look at.
Does anyone know what I can expect from custom/duties charges if I purchase a watch in the Netherlands (ex-VAT) and have it shipped to Boston? Anyway around it? Strap would not be any sort of leather if that matters.
