What people say

Owners + reviewers, side by side

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

Glycine Airman Vintage The Chief GMT

Owners widely appreciate the Glycine Airman Vintage The Chief GMT for its historical significance and homage to the 1953 original. However, one owner notes criticism regarding the main hour hand being a 12-hour hand on a 24-hour dial, which hinders its intended use and compromises the bezel's functionality, leading to a return. On balance, owners value the Glycine Airman Vintage The Chief GMT for its historical connection, though a functional critique exists regarding its hour hand implementation.

Oak & Oscar The Humboldt Seven Year

Oak & Oscar The Humboldt Seven Year owners note the hand-machined brass bezel and hand-finished dial. One owner reports the Sellita SW300 movement timed at -5 seconds per day, and another owner observed minor imperfections on the dial and crystal, along with a small ding on a lug. On balance, owners appreciate the unique dial and bezel finishing, though some minor cosmetic flaws have been noted.
