THE PIERCE WATCH WAS HIGHLY RESPECTED.
BOASTING SHOCK PROTECTION, WATER PROTECTION AND AIRTIGHT, MANY WERE SOLD IN THE USA AND
OVERSEAS PRIOR TO AND DURING WWII.
THE INCABLOC WAS THE FIRST BALANCE
SHOCK ABSORBER SYSTEM UTILIZING DUAL JEWELS WITH A BRASS SPRING SYSTEM... BUT IT WAS
PATENTED. SO PIERCE UTILIZED THE COMPETING SYSTEM CALLED THE PARASHOCK SYSTEM. BOTH WERE
UTILIZED IN MILITARY WATCHES.
*************************************************
WWII
CENTER SWEEP
Prior to WWII, most watches had a sub-second register above the #6 position. This design
failed to allow precision seconds timing. The sub-second style dial, with a tiny second
hand rotating around a tiny seconds register at the 6 position, was difficult to utilize
for timing events. In most cases it was ignored. On the other hand, a sweep second hand
could be used to time events, mark events, and was easier to read .
By 1942, the sweep second hand watch had became
"the" watch. Two of the major reasons were the Government issued U.S.A. A-11
hacking sweep seconds pilots watch and the sweep seconds watches in demand by Doctors,
Medics and Nurses and other professionals.. The sweep second watch simply made the watch
more than an instrument to "tell time"....
THE DESIGN
So, what did Pierce and others do?
Did they re-tool and re-design new movements? NO!
They simply placed a hollow canon pinion that
allowed a wheeled center shaft to protrude through the dial, mounted a second hand to it,
and ran the combo with the very sub-seconds wheel they were eliminating...

Instead of the drive train turning the dial
protruding shaft/pinion at 6 position connected to the tiny second hand, they mounted a
large brass/alloy wheel on the opposite side of the shaft that now protruded through the
bridge. That wheel turned a wheel on top of a NEW center "shaft' held in position be
a new this jeweled bridge that went through a new HOLLOW center cannon pinion in the
center of the movement that then protruded through the center of the dial where a new long
sweep second hand attached; the idea being that one had a large second hand that
went round in tune with the movement and the chapter ring so one could count, time &
now even synchronize.
