The short answer
The closest alternative to the Undone Aquadeep K9 is the Seiko Prospex Sea PADI Special Edition ($625) — pro diver and Visually similar. If price is the constraint, the Seiko 5KX at $350 (vs $1,150 for the Aquadeep K9) covers most of the same brief. From the independents, the Amaux Boze Turbinant is the standout microbrand take — shared caliber (Seiko NH72) and Pro diver. Stepping up, the Linde Werdelin Oktopus Moon ($19,048) is where the same idea goes with a bigger budget.
