The short answer
The closest alternative to the Borealis Watch Co. Caloura 300m is the Seiko Prospex Sea ($625) — common cross-shop and Pro diver. From the independents, the Spinnaker Tesei Titanium is the standout microbrand take — common cross-shop and Shared caliber (Seiko NH35). Stepping up, the Tissot Seastar 1000 ($875) is where the same idea goes with a bigger budget.
