The short answer
The closest alternative to the Sangin Instruments Neptune is the Yema Superman Dato CMM.10 ($1,777) — pro diver and Looks nearly identical. If price is the constraint, the Orient AC0Q Diver II LE at $395 (vs $1,599 for the Neptune) covers most of the same brief. From the independents, the Marin Instruments Steel Skin-Diver S is the standout microbrand take — shared caliber (Automatic (Sellita SW300)) and Vintage revival. Stepping up, the Bremont Supermarine 300M ($3,550) is where the same idea goes with a bigger budget.
