What to know

Marathon’s 46mm Anthracite Jumbo Diver’s Automatic brings the brand’s blacked-out treatment to its largest standard Search and Rescue case. The steel watch measures 55mm lug to lug and 18mm thick, with a sapphire crystal, unidirectional bezel and 30 ATM water resistance.

A Sellita SW220 automatic movement supplies both day and date indications. The dial combines self-powered tritium tubes with MaraGlo accents, while the screw-down crown and 22mm rubber strap suit the JDD’s oversized tool-watch brief. Reference WW194021BK-0130 entered the expanded anthracite line in 2026 at a listed European price of €3,250.
