The short answer
The closest alternative to the Marnaut Safe Harbour 100C is the Marathon Steel Navigator SSNAV Auto ($1,300) — shared caliber (Sellita SW200-1) and Pro diver. If price is the constraint, the Orient AC0Q-40 Diver Watch at $370 (vs $899 for the Safe Harbour 100C) covers most of the same brief. From the independents, the Timefactors Royal Navy Diver PRS-82 is the standout microbrand take — shared caliber (Sellita SW200-1) and Pro diver. Stepping up, the Marathon Jeep Rubicon GSAR ($2,100) is where the same idea goes with a bigger budget.
