The short answer

The closest alternative to the Seagull Ocean Series Pro 300m Waterproof Sandblasted Dial 3D Titanium Ceramic Bezel Diving Watch 43.5mm is the Seiko Prospex Sea ($625) — pro diver and Looks nearly identical. If price is the constraint, the Swatch Sistem Lake at $230 (vs $499 for the Ocean Series Pro 300m Waterproof Sandblasted Dial 3D Titanium Ceramic Bezel Diving Watch 43.5mm) covers most of the same brief. From the independents, the Seagull Ocean Series Pro 300m Waterproof Diving Watch 44mm is the standout microbrand take — shared caliber (Seagull ST2130) and Same family (Dive Watch). Stepping up, the Fortis Marinemaster M-44 ($5,120) is where the same idea goes with a bigger budget.
