48 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Marathon MSAR (Medium Search & Rescue) Diver's Quartz is the Marathon TSAR (Tritium Search & Rescue) Diver's Quartz ($1,550) — shared caliber (Swiss High-Torque Quartz) and Pro diver. If price is the constraint, the Tissot Seastar 1000 at $515 (vs $1,450 for the MSAR (Medium Search & Rescue) Diver's Quartz) covers most of the same brief. From the independents, the CWC SBS 1987 Aged Special is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the TAG Heuer Aquaracer ($2,550) 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.
