The short answer

The closest alternative to the Longines HYDROCONQUEST is the Bremont Supermarine 300M ($3,550) — common cross-shop and Pro diver. If price is the constraint, the Tissot Seastar 1000 at $875 (vs $2,350 for the HYDROCONQUEST) covers most of the same brief. From the independents, the BOLDR Supply Co. Odyssey Luminaire Aetherfire is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Breitling Superocean Heritage 57 Highlands ($6,900) is where the same idea goes with a bigger budget.
