How to determine metal type on a President bracelet link?

[miamiclay]

Single 16mm WG link (without screw) shows 2 grams on my kitchen scale, which doesn’t give tenths of a gram.
It seems most likely yours is WG - If it were platinum at 2.1g, then a WG link should be 1.4g, which I *presume* my scale would round down to 1g (?).

Do you know the year it came from? One other complicating weight factor might be that they put ceramic sleeves only in the platinum DD bracelets at first, which would presumably affect the weight.
