The short answer

The closest alternative to the Sangin Instruments Neptune is the Yema Superman Gilt CMM.10 ($1,699) — pro diver and Looks nearly identical. If price is the constraint, the Orient AC0Q-40 Diver Watch at $370 (vs $1,599 for the Neptune) covers most of the same brief. From the independents, the ZRC 1904 IRIDIUM -METAL is the standout microbrand take — shared caliber (Sellita SW300-1) and Pro diver. Stepping up, the Bremont Supermarine 300M ($3,550) is where the same idea goes with a bigger budget.
