What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Box Ceramic

Owners widely praise the Glycine Combat Sub Box Ceramic for its exceptional thinness at 10.4mm for a 42mm diver, perfect proportions for small wrists, and unique, non-homage aesthetic, with some considering it the best dive watch under $400 due to its superior finishing and value. The case shape, dimensions, and drilled lugs are also highlighted as positives, and the dial is legible with good lume on the hands. However, reviewers and owners consistently flag sub-par lume on the markers that fades quickly, and an inconsistent power reserve. Some owners report the stock strap or bracelet is subpar, and one owner experienced the bezel detaching after a light bump, questioning build quality. Accuracy figures vary, with one owner noting it runs about 2.5 seconds fast per day, while another reports an inconsistent power reserve. On balance, owners rate the Glycine Combat Sub Box Ceramic highly for its thinness, unique design, and value, despite concerns about lume and strap quality.

Oak & Oscar The Humboldt GMT

Oak & Oscar The Humboldt GMT owners widely praise its exceptional accuracy, often running at or near 0 seconds per day, and its comfortable wearability with subtle design details. The construction quality for the price point, sandwich lume, and anti-magnetic properties are also highlighted. Some owners find the bracelet sizing adjustment slightly awkward, and one noted the lume could be brighter. Overall, owners rate the Oak & Oscar The Humboldt GMT highly for its accuracy and comfortable wearability.
