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 Captain Willard

The Seiko Prospex Sea 1970 Diver's Modern Re-interpretation is praised for its impressive finishing and value, with reviewers noting its well-designed dial and excellent LumiBrite lume. The watch features a textured grey or dark brown dial, silver hands and indexes with beige or cream lume, and a matte grey or dark bezel insert. It houses the 6R35 automatic movement with a 70-hour power reserve. Some reviewers question if its performance specs align with its price point. Overall, reviewers rate the Seiko Prospex Sea 1970 Diver's Modern Re-interpretation highly for its finishing and value over $1,000.
