In brief
The sub-seconds branch stops here. A flat hairspring and Novochoc shock protection were the last additions Omega made, laid over the 17 jewels and 18,000 vph already standard across the 26x series.
Short history
Omega's own technical guide of 1963 is blunt about it: the 269 is a renamed 268, the new number following the fitting of a flat hairspring and Novochoc shock protection — the same pair of changes that produced the 286 in the centre-seconds branch. Together those two are the last technical link in the whole 30T2 family, which was withdrawn that same year and replaced by the full-rotor automatics.
