With an appearance between blue and grey, Sea Grey 637 makes for a unique neutral pairing with Dive and Pilot pieces as well as with monotone dial designs.

Equipped with vintage aviation features including a distinctive 6mm engraved rivet, bead blasted aviator roller buckle and a sightly tapered profile leading from a 20mm start to a 18mm buckle.
