The short answer

The closest alternative to the Marnaut Safe Harbour 100C Safe Harbour Classic 100 (cushion case, multi-subdial complication, applied batons) is the Artefkt Field Watch ($1,850) — shared caliber (Sellita SW200-1) and Pro diver. If price is the constraint, the Alexander James Watches A4 Legacy Dress 37 pilot/field 3-hand date, printed Arabic numerals (PVD cushion case) at $200 (vs $1,042 for the Safe Harbour 100C Safe Harbour Classic 100 (cushion case, multi-subdial complication, applied batons)) covers most of the same brief. From the independents, the Marnaut Safe Harbour 100 is the standout microbrand take — shared caliber (Sellita SW200-1) and Same family (Safe Harbour). Stepping up, the Longines ULTRA‑CHRON CARBON ($5,550) is where the same idea goes with a bigger budget.
