Marathon - 46mm Jumbo Day/Date

WHAT WE LOVE:

The Marathon Jumbo Day/Date Automatic (JDD) (Ref. 6645-21-886-8975) is a highly capable military dive watch, designed to meet the extreme demands of search and rescue teams operating in the harshest conditions. Built from 316L stainless steel, its imposing 46mm case provides exceptional durability, while the 120-click unidirectional bezel ensures precise elapsed time tracking. With a 300m water resistance rating and ISO 6425 compliance, the JDD is engineered for serious diving and operational use.

The watch’s black dial offers exceptional legibility, featuring bold, tritium gas tube illumination that ensures visibility in total darkness without the need for external charging. Large, luminous hands and indices provide at-a-glance readability, while the inclusion of a day-date complication at 3 o’clock adds practical functionality.

The screw-down crown and helium escape valve make the JDD a resilient choice for professional divers and military personnel operating in extreme conditions. The uni-directional rotating bezel with a 60-minute scale provides precise tracking of elapsed time, while the watch’s sapphire crystal is scratch-resistant and highly durable.

WHAT'S INSIDE:

Powering the watch is the Marathon M2 movement, a Sellita SW220-1 automatic Swiss-made caliber with a 38-hour power reserve and Incabloc shock protection, ensuring robust performance in the harshest conditions.
