The short answer
The closest alternative to the Aera Instruments D-1 is the Marathon GSAR (Government Search & Rescue) Diver's Automatic ($2,100) — shared caliber (Sellita SW200-1) and Pro diver. If price is the constraint, the Damasko DSub50 covers most of the same brief. From the independents, the Aera Instruments D-1 Diver is the standout microbrand take — shared caliber (Sellita SW200-1) and Same family (D-1). Stepping up, the Breitling Avenger Automatic 45 Seawolf ($4,400) is where the same idea goes with a bigger budget.
