Well as I say, the hands are wrong, the chrono is too early (or a modern relume) and the others are possibly from a Mk2. That aside, I am no fan of the 1116 bracelet, very rattly, that one looks tired. Avoid unless stupidly cheap.
I would recommend checking out Omega forum member @Spacefruit's very informative vintage Speedmaster web site.
