The closest alternative to the San Martin 36mm/39mm/42mm SN0144 is the Citizen Tsuyosa Automatic ($356) — common cross-shop and Visually similar. If price is the constraint, the Seiko 5 SNKK27K1 at $133 (vs $317 for the San Martin 36mm/39mm/42mm SN0144) covers most of the same brief. From the independents, the Astor + Banks Fortitude Pro is the standout microbrand take — shared caliber (Miyota 9015) and Visually similar. Stepping up, the Christopher Ward C63 Sealander Rocks ($1,350) is where the same idea goes with a bigger budget.
