The closest alternative to the Aquastar Airstar Chronograph is the Fortis Flieger F-43 Bicompax ($4,180) — looks nearly identical and Automatic. If price is the constraint, the Tissot T-Race at $875 (vs $2,590 for the Airstar Chronograph) covers most of the same brief. From the independents, the Cooper Watches MWC 24 Jewel 1982 Pattern 300m Automatic Military Divers Watch with Sapphire (Date) is the standout microbrand take — looks nearly identical and Automatic. Stepping up, the Omega Seamaster Aqua Terra 150M Co Axial Master Chronometer ($6,700) is where the same idea goes with a bigger budget.
