A really wonderful patinaed brass, in a slightly looser-weaved chain than the Studebaker signature bracelet. I really like that, because it wears very lightly and is super breathable. Just a really comfortable, really nice piece.
My only criticism is the clasp, which is prone to coming undone by gravity. Keep the clasp on the top of your wrist and it’s better. You can also bend the metal, not take it off, and obviously it’ll be secure then.
