Signum Cero
50 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Signum Cero is the Arethusa Watch Co World Diver — shared caliber (Seiko NH35) and Pro diver. If price is the constraint, the Aigi Watches BARENTS SEA AUTOMATIC round dive watch 43mm, applied markers + date + dive bezel at $180 (vs $519 for the Cero) covers most of the same brief. From the independents, the Sheffield Allsport Diver 1 is the standout microbrand take — shared caliber (Seiko NH35) and Pro diver. Stepping up, the Tudor Pelagos ($6,025) is where the same idea goes with a bigger budget.
Independent makers covering the same brief — usually with something the mainstream brands don't.
