The short answer

The closest alternative to the Pagani Design PD-1821 is the Seiko Prospex Sea — common cross-shop and Pro diver. From the independents, the Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18 is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Citizen Promaster Fujitsubo ($1,195) is where the same idea goes with a bigger budget.
