The short answer

The closest alternative to the Bremont Supermarine 300M is the Longines LEGEND DIVER ($3,850) — common cross-shop and Pro diver. If price is the constraint, the Yema Superman Gilt CMM.10 at $1,699 (vs $3,550 for the Supermarine 300M) covers most of the same brief. From the independents, the Specht & Sohne Specht & Söhne SP2653 Automatic is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Omega Seamaster 300 Co Axial Master Chronometer 41mm ($8,000) is where the same idea goes with a bigger budget.
