The short answer
The closest alternative to the Synchron Ti300M Poseidon Deep Black is the Tissot Seastar 1000 ($875) — pro diver and Looks nearly identical. If price is the constraint, the Timex Expedition Pioneer Titanium Automatic GMT at $629 (vs $1,490 for the Ti300M Poseidon Deep Black) covers most of the same brief. From the independents, the Méraud Bonaire is the standout microbrand take — shared caliber (La Joux-Perret G100) and Pro diver. Stepping up, the Fortis Novonaut N-42 ($5,230) is where the same idea goes with a bigger budget.
