North Field Reef Diver 40

The North Field Reef Diver 40 is a mid-size dive watch sized for narrower wrists and smaller cuffs without giving up working capability. The 40mm 316L stainless case wears 12.4mm thick, with a 60-click unidirectional bezel insert in scratch-resistant ceramic and a domed sapphire crystal with internal anti-reflective coating.

Inside is a Swiss automatic movement with 56 hours of power reserve and hacking seconds for time-syncing before a dive briefing. Water resistance is 200m with a screw-down crown and case back. The dial is matte black with broad rectangular indices and a snowflake minute hand, drawn from the legibility standards North Field developed for North Atlantic charter boats.

Shipped on a brushed three-link bracelet with a milled clasp and on-the-fly micro-adjust. A ribbed FKM rubber strap is included for warm-water work. The Reef Diver is the everyday North Field — equally at home on a recreational dive or under a long-sleeve shirt.
