Reviews

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

San Martin Compressor Diver

Owners praise the San Martin Compressor Diver as a favorite with a retro diver character, and one notes the big numerals grow on them, though they regret the original black dial didn't sell better. One owner reports timekeeping of only about 20 seconds gained every 12 days under daily wear with the NH35 movement, which is a strong result for an automatic. Weaker points include lume that one owner finds much weaker than expected for the brand, and a lollipop seconds hand that another considers oversized against the dial. Overall, owners rate the Compressor Diver well for its retro homage character and accuracy, with lume the most notable drawback.

Zelos Swordfish 40mm SS (Ceramic Case)

The Zelos Swordfish 40mm SS (Ceramic Case) is widely regarded as an exceptional value dive watch, with reviewers and owners highlighting its textured sandwich dial, ceramic bezel insert, and sapphire crystal. Owners praise its comfortable fit due to the 40mm case size, depth, and short lug-to-lug distance. One owner specifically appreciates the full lume dial. The watch is powered by a Seiko NH35 automatic movement and offers 200m water resistance. On balance, owners and reviewers rate the Zelos Swordfish 40mm SS (Ceramic Case) highly for its impressive features and comfortable wearability at its price point.
