Esoteric Watches Bathyal SolvsSeiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition

The Esoteric Watches Bathyal Sol is widely praised for its attractive and unique design, featuring a matte yellow dial with deep sandwich cutouts and old radium lume, complemented by a bezel with deeply grooved, enamel-filled markers. Owners describe it as a dense, hefty, "go anywhere" watch with "insane" lume, noting its homage to the Bulova Snorkel 774. One reviewer flagged potential confusion with the "Eso" vs. "Esoteric" branding and expressed concerns about the long-term durability of the matte black DLC coating. On balance, owners and reviewers rate the Esoteric Watches Bathyal Sol highly for its distinctive dial and robust, go-anywhere build.

The Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition is praised for its beautiful design and refinement over previous models, featuring vertically textured glacier-inspired dials. Owners, however, consider the €1500 RRP too high, suggesting a price closer to €900-€1000, noting the aluminum bezel insert instead of ceramic. Some owners report the 6R movement runs slow. On balance, owners find the Seiko Prospex Sea 1970 Heritage Diver's Save the Ocean Special Edition beautiful and a refinement, but the price and aluminum bezel are points of contention.
