Ref. 329.32.44.51.01.001 – These models owe their name to the offset minute track on the dial, designed in a racing style. This style harks back to a 1968 Speedmaster design that offered the wearer improved legibility. Other dial features include Super-LumiNova-filled, beveled arrowhead hour markers and large subdials. The 44.25 mm watch is crafted from materials such as stainless steel or 18K Sedna™ gold, with elegant ceramic used for the bezels. The sapphire crystal has also been redesigned to give the watch a slimmer profile.
