I've no idea why but Breitling, like most manufacturers, don't make their manuals available in pdf form online.
The M1 uses an ETA 251.232 movement and you can download the tech spec here.
http://www.cousinsuk.com/PDF/categories/23_ETA251.232.pdf It also has a useful guide to resetting the hands if they get out of sync.
Chase-Durer are one of the few companies who do make their manuals available and their Falcon Command uses the ETA 251.262 movement which is the non-thermocompensated (or non "SuperQuartz" in Breitling terminology) version.
