Seaholm Flats Chronograph

Availability: Out of stock
Delivery time: Ships in 2-3 days

The Flats is a chronograph designed for miles of shallow flats. While most chronograph watches use the stopwatch function to determine speed, Seaholm has 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 is a certified dive watch built for extreme marine conditions

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