39 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Ratio FreeDiver Professional Sapphire RTF0xx is the Casio MDV-106 Duro ($85) — pro diver and Visually similar. If price is the constraint, the Casio WS-1400H-1BV at $40 (vs $110 for the FreeDiver Professional Sapphire RTF0xx) covers most of the same brief. From the independents, the Ratio FreeDiver 1000M 1038EF102V-BLU Men's Watch is the standout microbrand take — same family (FreeDiver) and Pro diver. Stepping up, the Glycine Men's Combat Sub Sport 42mm Quartz Watch GL1018 ($995) 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.
If the price is the only thing keeping you off this watch, these get you most of the way there for less.
Where the same idea goes when budget isn't the constraint: luxury upgrades and step-ups.
