The short answer

The closest alternative to the Seagull Ocean Series Ultra 1000m Waterproof Helium Valve Design Integrated Rotating Bezel Diving Watch 45mm is the Tissot Seastar 2000 ($1,275) — pro diver and Looks nearly identical. If price is the constraint, the Citizen Promaster Diver Automatic at $469 (vs $1,049 for the Ocean Series Ultra 1000m Waterproof Helium Valve Design Integrated Rotating Bezel Diving Watch 45mm) 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 Breitling Superocean Automatic ($5,700) is where the same idea goes with a bigger budget.
