Flats Chronograph

Bracelet size

The Flats is a chronograph designed for miles of shallow flats. While most chronograph watches use the stopwatch function to determine speed, we've turned the tachymeter scale on its head and adapted the stopwatch function to judge distance. For someone on the flats or in the open expanses of the backcountry, the Flats can be used to calculate the distance of a coming storm.

Water resistant to Diver’s 200M, the Flats watch is a certified dive watch.

Each Flats Chronograph watch comes with a stainless steel bracelet and NATO strap as shown.
