|These Racing dials have vivid, contrasting colors on the outer track, which is intended to make the chronograph simpler to read at a glance. Similarly, the hands are in a bright red-orange hue, and most examples seem to feature a running seconds hand of the same color. The running seconds counter and hands also appeared in white.|
We’ll see several editions of these dials over the years, most notably the following:
Ref. 145.012-67 Speedmaster ‘Red Racing’ in 1968, which uses the Caliber 321 and features a dot-over-ninety bezel;
Ref. 145.022 ‘Orange Racing’ in 1968, which is characterized by orange paint on the outer track and orange chronograph seconds hand;
Ref. 145.014 Speedmaster Professional Mark II in 1969, also known as the “exotic” dial variant, which was later reissued in 2014;
and the Ref. 3570.40.00 Japan Racing Edition in 2004, which was exclusive to the Japanese market and had the Caliber 1861 at its core.
