CEAS ZENITH PILOT - "BUMPER' - Cal. 133.8 - Automatic - 1959 - F. RAR !

Ceas : ZENITH PILOT

- Mecanism : Bumper automatic, cal 133.8

- "The cal 133.8 movement, a bumper automatic with 20 jewels running at 21,600 bph, is one of first Zenith automatic movements (together with cal. 133), and the first movement in the world to have direct central second hand.. There were 77.000 watches produced with this caliber between 1951 and 1958. Theoretically, production of the 133.8 ceased in 1958, but it would appear from the existence of this item that in fact, some units were manufactured early the next year. Whatever, we can say for sure that this is one of the very last bumper automatics to ever have been built by Zenith."

"What makes it such an unusual piece is that this movement is a bumper, rather than rotor, automatic. Rotor automatics, which are now the universal standard in the luxury watch industry, have centrally pivoted weights that spin when moved by gravity. These turn in a full 360 degrees, winding in either one, or in some instances, both directions as they travel. The bumper was built along entirely different lines. There is still a pivoted weight, but this only moves through a limited arc of travel and cannot rotate freely. Once it swings out to its fullest extent, it is bounced back off buffer springs in the direction from which it came. It is this rocking, bouncing motion, which can be felt on the wearer’s wrist, that led to movements of this type being known within the collecting community as bumpers."
