The short answer
The closest alternative to the Borealis Watch Co. Jamanta is the Seiko Prospex Sea ($625) — common cross-shop and Pro diver. If price is the constraint, the Swatch Sistem51 Hodinkee Generation at $170 (vs $415 for the Jamanta) covers most of the same brief. From the independents, the Balticus Watches Balticus Deep Water is the standout microbrand take — shared caliber (Miyota 9015) and Pro diver. Stepping up, the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch Limited Edition ($1,750) is where the same idea goes with a bigger budget.
