The short answer

The closest alternative to the MKII Project 300 is the Fortis Flieger F-41 ($2,530) — pro diver and Looks nearly identical. If price is the constraint, the Tissot Seastar 1000 at $875 (vs $1,995 for the Project 300) covers most of the same brief. From the independents, the Whitby Watch Co. Intrepid Diver is the standout microbrand take — shared caliber (ETA 2824-2) and Pro diver. Stepping up, the Omega Seamaster Diver 300M Co Axial Master Chronometer 42mm ($6,300) is where the same idea goes with a bigger budget.
