Reviews

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

Meridiano Watches Lost Astronaut

The Meridiano Watches Lost Astronaut is praised for its bold, colorful, and amazing dial with creative lume application. Owners express strong desire and satisfaction with the aesthetic, with one builder noting appreciation for the case's match with the dial and oversized hands. The watch is described as a custom build using parts from various sources. Overall, owners rate the Meridiano Watches Lost Astronaut highly for its unique and exciting dial design.

Seiko Baby Alpinist

Owners widely praise the Seiko Baby Alpinist for its attractive design, legible dial, and comfortable 38mm cushion case that wears smaller than its dimensions suggest. Reviewers and owners alike highlight the watch's excellent value, particularly when on sale, and appreciate its finishing, including outstanding brushing and a gorgeous reflective dial with applied indices. Some reviewers note the internal rotating bezel action is good for the price, though not as refined as higher-end models, and one owner would prefer a numbered bezel. A drawback mentioned by one owner is the lack of AR coating, and accuracy is reported by one source as approximately -10 seconds per day. The stock strap is frequently described as stiff and uncomfortable, though owners find success with break-in or replacement. Overall, owners and reviewers rate the Seiko Baby Alpinist highly for its comfortable wearability and attractive finishing at a fair price.

From video reviewers

The watch's bezel action is smooth and precise. The watch's lume is somewhat lacking, with the hour markers not being as bright as they'd like. Reviewers disagree on the ideal case size, with some preferring 38mm and others 41.4mm.
