Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners report the Aigi Arctic Tide's dial markers catch the light similarly to Grand Seiko dials, and one user noted a preference for its movement over an alternative. Some owners consider the 40mm case size comfortable, while others found a 43mm variant chunky. One owner received their watch with a Miyota 9015 movement upgrade, and another experienced issues with lume and alignment on their initial unit, receiving a replacement. On balance, owners view the Aigi Arctic Tide as a decent value at its Kickstarter price, with good on-paper specifications, though concerns exist regarding the brand's newness and potential for it to be a catalogue watch.
The Santurce El Tiburón features a 39mm sandblasted steel case and a flat sapphire crystal with no glare. Reviewers praise its smooth and secure bezel action, along with excellent and even luminous material application on the hands and markers. Overall, owners rate the Santurce El Tiburón highly for its glare-free crystal and excellent lume application.
