This has a very solid weight of 269 grams, or 9.48 troy ounces. It is 9 inches / 23cm long, the links are 20mm wide and 8mm thick. The clasp clips tightly shut and the safety stays also clip tightly into place. The clasp is hallmarked 925. It is in good used condition but expect there to be marks from usage. This is definitively an impressive statement piece and is sure to last a lifetime.
