The short answer
The closest alternative to the Undone X POPEYE "SEAWEED" is the Invicta Pro Diver 8929OB — shared caliber (Seiko NH35) and Skin-diver style. If price is the constraint, the Casio Edifice EFK-100D covers most of the same brief. From the independents, the Undone X POPEYE "Blacksand" Automatic is the standout microbrand take — shared caliber (Seiko NH35) and Skin-diver style. Stepping up, the Longines LEGEND DIVER BRONZE ($3,550) is where the same idea goes with a bigger budget.
