The Nautical Microsecond Chronograph pairs sporting functionality with timeless American design. The complex super runner movement and intricate black 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 striking timepiece. The elegant brown 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]
