The short answer

The closest alternative to the Seiko Prospex Sea is the Tissot Seastar 1000 ($515) — common cross-shop and Pro diver. If price is the constraint, the Tissot PR 100 Jungfraubahn at $395 (vs $795 for the Prospex Sea) covers most of the same brief. From the independents, the Vaer DS2 Meridian Quartz 36mm is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the TAG Heuer Aquaracer ($2,550) is where the same idea goes with a bigger budget.
