Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Aigi Watches The Banzai Watch is praised for its dial's triangular texture, which catches sunlight and adds character. Owners note the watch has good specifications for its $199 Kickstarter price. Some find its 40mm case size and 49mm lug-to-lug measurement to be chunky. There is skepticism regarding the brand's longevity and origin, with some suggesting more established brands for a safer purchase. One owner reported receiving the watch with a Miyota 9015 movement upgrade. On balance, owners value the dial's unique texture and the watch's specifications for the price, despite concerns about the brand's establishment.
The Seiko 5 Sports Field series is praised for its accessible explorer watch design and decent fit and finish for its price point. Reviewers note the inclusion of a caller GMT complication powered by the 4R34 automatic movement. On balance, owners and reviewers find the Seiko 5 Sports Field series a compelling option for its explorer aesthetic and GMT functionality at an accessible price.
The prominent five-sided GMT hand enhances legibility and adds a sophisticated aesthetic to the watch. The Seiko 5 Sports Field series offers similar functionality to the Explorer 2 at a lower price, making it a valuable option. Reviewers disagree on whether it's a missed opportunity for Seiko to release this model first, with one reviewer implying it would have been a more logical addition to their lineup.
