Top Time B01 – RB01761A1Q1X1

The 1960s was a decade of experimentation, fun, freedom and energy. Whether cruising on a motorcycle or revving up a sportscar, living life at full speed was the order of the day. Willy Breitling felt this change of pace and set out to design an unconventional chronograph that would capture the verve of era. He called it the Top Time.\nThat spirited tradition continues today with the Top Time B01 that features a perforated leather racing strap, speed-measuring tachymeter scale and contrasting “squircle” (not quite square, not quite round) subdials that give the feel of a vintage dashboard gauge. It also comes with a brag-worthy engine under the hood: the exceptional Breitling Manufacture Caliber 01.
