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.

Seiko Prospex Sea Save the Ocean Special Edition

Owners widely praise the Seiko Prospex Sea Save the Ocean Special Edition for its exceptional and captivating dial designs, often described as a highlight that evokes ocean surfaces with unique textures and color gradients. The watch is frequently noted for its excellent value, with some reviewers comparing its aesthetics to much higher-priced brands. Owners report satisfactory lume and accurate timekeeping, with figures ranging from +5 seconds per day to more precise results. However, some owners and reviewers point to the bracelet clasp as a point of criticism, describing it as underwhelming or flimsy, and some find the watch to be top-heavy. There are also mentions of imperfect day/date wheel alignment and occasional bezel alignment issues on some models within the line. The Seiko Prospex Sea Save the Ocean Special Edition is available in various case sizes, with some owners questioning if certain dimensions are too bulky for daily wear.
