The short answer

The closest alternative to the Grand Seiko SLGA001 is the Grand Seiko SLGA015 ($12,600) — shared caliber (Grand Seiko 9RA5) and Same family (Evolution 9). If price is the constraint, the Tissot Seastar 2000 at $1,275 (vs $11,100 for the SLGA001) covers most of the same brief. From the independents, the Phoibos Leviathan is the standout microbrand take — pro diver and Looks nearly identical. Stepping up, the Blancpain Bathyscaphe ($26,000) is where the same idea goes with a bigger budget.
