The short answer
The closest alternative to the Undone Aquadeep Signal Automatic is the Invicta Pro Diver 0420 — shared caliber (Seiko NH35) and Pro diver. If price is the constraint, the Swatch Am51 at $170 (vs $395 for the Aquadeep Signal Automatic) covers most of the same brief. From the independents, the Undone AquaLume Orange Rubber Automatic is the standout microbrand take — shared caliber (Seiko NH35) and Pro diver. Stepping up, the Seiko Prospex Sea 1968 Heritage Diver's GMT Watch ($1,700) is where the same idea goes with a bigger budget.
