The short answer

The closest alternative to the San Martin 2025 Upgraded 40mm Diver Watch SN0118G-B is the Invicta Pro Diver 8927OB — shared caliber (Seiko NH35) and Skin-diver style. If price is the constraint, the Casio Edifice EFK-100D covers most of the same brief. From the independents, the Zelos Swordfish 3 is the standout microbrand take — common cross-shop and Shared caliber (Seiko NH35). Stepping up, the Seiko HBC003J1 ($995) is where the same idea goes with a bigger budget.
