mbk bracelet is all wrong. there are two different ones too. 1 comes with all subs and the other comes with the 1665. they both say 93150 on them but the 1665 one is the better one.
the 1665 is the right thickness of links and not polished on the sides. the mbk end connecting link is incorrect, and the taper on the bracelet is too drastic. the 1/2 size adjustment holes on the clasp side are also in the wrong layout, they are arranged for a 93250. i believe the diving extension is also stamped backwards compared with gen.
the mbk bracelet is not suitable.
TC would have to make one from scratch in my opinion to get it right, but if he did i would be in to buy one.
