Inspired by the racing scene of simpler times, the Autodromo Monoposto Chronograph — whose name literally means single seat — is back to celebrate the brand’s fifth anniversary, this time in chronograph form. Part of a limited run like their previous Monoposto, 500 individually numbered units will be made of which 200 will have black dials, 200 silver dials, and 100 in Azzurro blue (shown). A Seiko NE88 automatic column wheel chronograph movement powers the watch, though it’s most distinctive feature is its domed sapphire crystal with a “redline” marker placed a bit above the 10 o’clock marker that’s evocative of the line of red paint or tape placed across the glass of yesteryear’s racer’s rev counter that dissuaded drivers from blowing their engines. Its sapphire crystal exhibition caseback also gives a peek through the polished stainless steel case at the movement within.
