Styled with an engine motif, the EF550PB-1AV is equipped with stacked sub-dials, which are strategically covered for enhanced legibility and a dynamic look. The sub-dial at the 3 o’clock position is designed to resemble a racing wheel. Armed with a 1/20th second retrograde chronograph, the second hand alternates between clockwise and counter clockwise motion during timed measurements.
