The short answer

The closest alternative to the Serket Watch Co Reef X is the Seiko 5KX ($350) — pro diver and Looks nearly identical. If price is the constraint, the Swatch The Swatch Sistem51 Hodinkee Summer Ed at $170 (vs $399 for the Reef X) covers most of the same brief. From the independents, the BERNY BERNY-Men Automatic Diver Watch-AM09026M is the standout microbrand take — shared caliber (Miyota 8215) and Pro diver. Stepping up, the Breitling Superocean Automatic ($5,700) is where the same idea goes with a bigger budget.
