The short answer

The closest alternative to the Undone Rikishi Shiro Ao — White Blue is the Hamilton Khaki Navy Scuba Auto ($975) — skin-diver style and Visually similar. If price is the constraint, the Swatch Blurang at $260 (vs $595 for the Rikishi Shiro Ao — White Blue) covers most of the same brief. From the independents, the Undone Rikishi Aka — Red is the standout microbrand take — shared caliber (Seiko NE57) and Pro diver. Stepping up, the Breitling Superocean Heritage 57 ($5,250) is where the same idea goes with a bigger budget.
