The Nautical Microsecond Chronograph pairs sporting functionality with timeless American design. The complex super runner movement and intricate white/blue dial combine to offer supreme accuracy as the second hand counts down to 1/20th of a second. Superluminova markings and a bold tachymeter add the finishing touches to this unique timepiece. The striking cobalt blue leather band can be swapped out with any 22mm Jack Mason strap making this a suitable choice for land, sea, brunch, or even a night out.[Details]
