·I believe the 77mil movement batch covers a range of Speedmaster models. I don't believe pieces are consecutively produced. I believe it is theoretically possible to have a FOIS numbered 77.727.123 and a Tintin numbered 77.727.124 followed by a consecutively numbered Soeedy Pro. My understanding is that Omega simply pulls out of the bin the escape wheel bridge with the movement number engraved on it from the supply bin and as such it depends on where in the series they started and stopped for the week or whatever. I am hoping that a more experienced member can lead us a bit further into the arcane workings of the Omega production line.
