Calibre 350 — centre seconds in the bumper series

In brief

Until the 350, the 28.1 mm bumpers all ran a small seconds sub-dial. This one moved the seconds hand to the centre and left the rest of the movement alone: 17 jewels, 19,800 vph.

Short history

In 1950 the 350 opened the centre-seconds branch of the bumper family, running alongside the sub-seconds 340 series and widening the dial options available at the same 28.1 mm diameter.
