The short answer
The closest alternative to the Seiko 5KX is the Seiko 5 Sports SKX series DENHAM Limited Edition, Seiko Boutique exclusive model ($430) — shared caliber (Seiko 4R36) and Same family (5 Sports SKX series). If price is the constraint, the Swatch Sistem Sea at $170 (vs $350 for the 5KX) covers most of the same brief. From the independents, the Borealis Watch Co. Caloura 300m is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Hamilton Khaki Navy Frogman Auto ($1,395) is where the same idea goes with a bigger budget.
