What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Esoteric Watches Bathyal Sol

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.

From video reviewers

The watch offers 60 ATM water resistance and uses a Miyota 9000 series movement. Reviewers did not identify any shared weaknesses or points of disagreement.

Timefactors SMITHS NATO PRS-40 AUTOMATIC

Owners widely praise the Timefactors SMITHS NATO PRS-40 AUTOMATIC for its unique, "badass," rugged, and futuristic design, with some finding its "ugly" aesthetic appealing for its bombproof nature. The Seiko 6R15 movement winds smoothly and operates quietly, and the watch features 100m water resistance and a flat sapphire crystal. The 12 o'clock crown is noted as easy to use by rolling, and the fixed lugs necessitate NATO straps. Some owners report issues with Timefactors' ordering system and customer service, and one found a speck of dust under the crystal, though another noted no imperfections. Overall, owners rate the Timefactors SMITHS NATO PRS-40 AUTOMATIC highly for its distinctive "beater" watch build and unique aesthetic at the price.
