The short answer

The closest alternative to the Duckworth Prestex Belmont 300 Automatic is the Alkin Watches Model Two ($582) — shared caliber (Miyota 9039) and Visually similar. If price is the constraint, the Aigi Watches BARENTS SEA AUTOMATIC round dive watch 43mm, applied markers + date + dive bezel at $180 (vs $750 for the Belmont 300 Automatic) covers most of the same brief. From the independents, the Venezianico Nereide Tungsteno 42 is the standout microbrand take — shared caliber (Miyota 9039) and Looks nearly identical. Stepping up, the Bremont Supermarine 300M ($3,550) is where the same idea goes with a bigger budget.
