The short answer

The closest alternative to the Bremont S300 is the Longines LEGEND DIVER 42 ($2,850) — common cross-shop and Pro diver. If price is the constraint, the Tissot Seastar Wilson WNBA at $875 (vs $3,795 for the S300) covers most of the same brief. From the independents, the Sternglas Marus 2.0 is the standout microbrand take — pro diver and Visually similar. Stepping up, the Tudor Black Bay 58 18K ($22,550) is where the same idea goes with a bigger budget.
