Got these from a friend and really have no use for them. The bracelet was originally fitted to a Flight Master, the clasp to a Dynamic. Now $175.US for both with PayPal and shipping, CONUS only, on me. What you see, is what you get. Thanx for your "time", Miki
Upon further review: @uwsearch is correct in both statements. Excluding the clasp, the bct looks exactly like a 1159 that's, with the 22mm ends, usually equipped on the Speedmaster MkIV style cases. It also looks bent and worn out. The 1153/138 is of different style and usually for the Dynamics. The whole thing is certainly usable if you keep it, and surely worth something for parts.
