The short answer
The closest alternative to the Synchron Poseidon Ice Diver is the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition ($1,750) — pro diver and Looks nearly identical. If price is the constraint, the Seiko Prospex Sea at $625 (vs $1,290 for the Poseidon Ice Diver) covers most of the same brief. From the independents, the Synchron Poseidon is the standout microbrand take — shared caliber (La Joux-Perret G100) and Same family (Poseidon). Stepping up, the Breitling Superocean Automatic ($5,700) is where the same idea goes with a bigger budget.
