The short answer

The closest alternative to the Seiko Sumo is the Tissot Seastar 1000 ($515) — common cross-shop and Pro diver. If price is the constraint, the Casio MDV-106 Duro at $85 (vs $762 for the Sumo) covers most of the same brief. From the independents, the Out of Order GMT is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Breitling Superocean Automatic ($5,700) is where the same idea goes with a bigger budget.
