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

Owners widely praise the Glycine Combat Sub for its exceptional thinness, with many noting its 10.4mm to 10.8mm profile for a diver, perfect proportions, and solid build quality that offers significant value, especially at discounted prices. Its unique aesthetic is appreciated for avoiding homage looks, and the lug design contributes to a smaller perceived wear size despite its 42mm case. Some owners report an inconsistent power reserve and sub-par lume that can be difficult to read at night, while one owner noted a slightly off-color lume pip on the chapter ring. Overall, owners rate the Glycine Combat Sub highly for its refined feel, slim profile, and value proposition.

Seiko 5KX

Owners widely praise the Seiko 5 Sports SKX series for its strong lume and comfortable wearability, with many noting its compact feel due to a short lug-to-lug length. The NH36 movement's accuracy varies, with typical performance between +/-5 to 10 seconds per day, though some report better. A lack of screw-down crown and ISO certification are noted drawbacks for its water resistance. Some owners find the bracelet to be of cheaper construction with hollow links, and a few have reported quality control issues. The consensus is that the Seiko 5 Sports SKX series offers good value for its price, appealing to those who appreciate its tool-like nature and iconic lineage.
