48 watches that match on case size, movement family, and price band. Sorted by how close the match is.
The closest alternative to the Seiko HBC011J1 is the Seiko Prospex Sea Seiko Prospex 1965 Heritage Diver’s Watch Save the Ocean Limited Edition ($1,400) — shared caliber (Seiko 6R55) and Pro diver. If price is the constraint, the Bulova Black Dial Stainless Steel Bracelet Vintage Sea Hunter 43B175 at $395 (vs $1,400 for the HBC011J1) covers most of the same brief. From the independents, the Zelos Swordfish 3 is the standout microbrand take — common cross-shop and Pro diver. Stepping up, the Fortis Marinemaster M-40 ($3,520) is where the same idea goes with a bigger budget.
Independent makers covering the same brief, usually with something the mainstream brands don't.
Established brands covering the same brief at a comparable price: same case size, similar movement family. Often the deciding click for a new buyer.
If the price is the only thing keeping you off this watch, these get you most of the way there for less.
Where the same idea goes when budget isn't the constraint: luxury upgrades and step-ups.
