The short answer

The closest alternative to the Synchron SEALAB Ti300M is the Christopher Ward C60 Trident Reef ($995) — pro diver and Looks nearly identical. If price is the constraint, the Timex Deepwater Reef 200 Titanium Automatic 41mm Synthetic Rubber Strap Watch at $589 covers most of the same brief. From the independents, the Synchron Poseidon is the standout microbrand take — shared caliber (La Joux-Perret G100) and Pro diver.
