Search and Rescue Medium Diver's Automatic

in Black Silicon Strap


All the robust dependability of a dive watch in a lightweight, everyday size

More commonly referred to as the “TSAR (Tritium Search and Rescue),” the Marathon Diver’s Quartz features a top-of-the-line Swiss-made automatic movement, and is fully ISO 6425-compliant, meaning it meets strict international standards for water resistance, durability, and dial legibility — the latter of which is provided by tritium illumination on the dial and hands, which produce a steady glow for up to 25 years.
