Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Ferro & Company TIME MASTER 70 BUBBLE GUM is praised for its 1970s-inspired design, featuring a unique case shape and dial layout, with reviewers and owners highlighting its comfortable 39mm wearability as a Goldilocks size. The watch is powered by a Miyota 9039 automatic movement and offers 100 meters of water resistance. One owner noted that a scratch-resistant coating offered during Kickstarter was not included in the final release. Overall, owners and reviewers rate the Ferro & Company TIME MASTER 70 BUBBLE GUM highly for its retro design and comfortable 39mm sizing at its US$650 price point.
The Mark Time Watches M 6 features a 39mm case and a Miyota 9039 automatic movement. Owners note the deep black dial creates a floating effect for the hands, and the second hand extends to the dial's edge. Praised are the absence of a ghost date position, a minimalist logo, and functional bezel screws. However, some owners report that telling time to the nearest minute or two is challenging. Overall, owners appreciate the M 6 for its thoughtful design details like the full-length second hand and bezel screws, despite minor legibility concerns.
The watch's lume is praised as a significant strength. Reviewers noted issues with the watch's finishing.
