The short answer
The closest alternative to the Undone Aquadeep Signal Automatic is the Seiko Prospex Sea ($625) — pro diver and Visually similar. If price is the constraint, the Swatch Waktu51 at $170 (vs $395 for the Aquadeep Signal Automatic) covers most of the same brief. From the independents, the Undone BRUTUS MONO Automatic is the standout microbrand take — shared caliber (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.
