Rego / Lapanouse was always a manufactory for simple pin lever movements. It is astonishing to see the high quality of the caliber 311, where all gears are beared in synthetic rubies, and the balance runs in two rare Palierfix shock protections. Even the hairspring contains a moveable stud and a regulator arm, and under the dial, you don’t find the expected rocker mechanism, but a much better yoke keyless works.
