The closest alternative to the Tissot Seastar 2000 Professional 44mm is the Seiko King Turtle ($650) — common cross-shop and Pro diver. If price is the constraint, the Orient RA-AC0K Diver Watch at $455 (vs $931 for the Seastar 2000 Professional 44mm) covers most of the same brief. From the independents, the Certina DS Super PH500M is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Bremont Supermarine Full Ceramic Deep Blue Nato Strap – Bremont Watch Company ($8,519) is where the same idea goes with a bigger budget.
