The short answer

The closest alternative to the Formex Reef 42 mm is the Seiko Prospex Sea 1968 Heritage Diver's GMT ($1,500) — pro diver and Looks nearly identical. If price is the constraint, the Tissot Seastar 1000 at $875 (vs $2,414 for the Reef 42 mm) covers most of the same brief. From the independents, the Formex Reef 39.5 mm is the standout microbrand take — shared caliber (Sellita SW300-1) and Same family (Reef). Stepping up, the Blancpain Bathyscaphe Chronographe Flyback ($22,800) is where the same idea goes with a bigger budget.
