The short answer

The closest alternative to the Marnaut Safe Harbour 100C is the Yema Navygraf Heritage ($990) — shared caliber (Sellita SW200-1) and Skin-diver style. If price is the constraint, the Orient Diver Design 40 at $395 (vs $899 for the Safe Harbour 100C) covers most of the same brief. From the independents, the Eza 1972 Diver is the standout microbrand take — shared caliber (Sellita SW200-1) and Skin-diver style. Stepping up, the Marathon Jeep Rubicon GSAR ($2,100) is where the same idea goes with a bigger budget.
