The closest alternative to the CWC (Cabot Watch Company) RN81 Diver Automatic Watch is the Glycine Men's Combat Sub 42mm Automatic Watch GL0186 ($1,530) — shared caliber (Sellita SW200-1) and Pro diver. If price is the constraint, the Yema Diver at $990 (vs $2,858 for the RN81 Diver Automatic Watch) covers most of the same brief. From the independents, the CWC RN81 Clearance Diver Automatic Watch is the standout microbrand take — shared caliber (Sellita SW200-1) and Pro diver. Stepping up, the Omega Seamaster Diver 300M Co Axial Master Chronometer 42mm ($9,600) is where the same idea goes with a bigger budget.
Independent makers covering the same brief, usually with something the mainstream brands don't.
Established brands covering the same brief at a comparable price: same case size, similar movement family. Often the deciding click for a new buyer.
