THIRD SERIES TUDOR CHRONO
The Big Blocks were Tudor’s third series of chronographs. The first Big Blocks were launched in 1976 and there were a number of obvious aesthetic differences to previous chronographs. The most striking detail was the introduction of a third chronograph register on the dial - an hour indicator.
PANDA AND REVERSE PANDA
Following the colourful Homeplate and Monte Carlo dials in the first two series of chronos, the introduction of the Big Blocks heralded a more understated ‘Daytona-esque’ dial; most commonly either black with silver/white subdials or vice versa.
A FIRST FOR TUDOR
The biggest development was the introduction of an automatic movement making these watches the first self-winding chronographs from the Wilsdorf group and over a decade before Rolex introduced their first automatic Daytona chrono.
ALL ABOUT THE BEZELS
There were three references of Big Block - distinguishable by the different bezel types.
