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 Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional value, thin profile, and solid build quality, often noting its finishing and wearability as superior for its price point. Reviewers consistently flag its slim case, with measurements around 10.4mm to 10.8mm, and appreciate its non-homage design and comfortable lug curvature. Accuracy figures vary, with one owner reporting only 2 seconds per day loss, while another notes their Sellita SW200 movement runs at +6 to +9 seconds per day. Some owners report inconsistent power reserve not reaching the advertised 42 hours and find the lume sub-par for nighttime legibility. A few also mention sharp bracelet edges and a potentially short bracelet for larger wrists, and one owner dislikes the "COMBAT" text on the dial. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its impressive thinness and value as a Swiss automatic diver.

Seiko Prospex LX line

Owners widely report the Seiko Prospex LX line's finishing is a step up from other models, with a case that sits well on the wrist, and some praise the green sunburst dial with blue anti-reflective sapphire crystal as phenomenal. However, owners note the high MSRP limited sales, with some desiring smaller cases and a reduced price, and others experienced quality control issues such as detached second hands and peeling DLC coating, leading to concerns about fragility. On balance, owners feel the Seiko Prospex LX line was discontinued due to pricing that alienated its target market, despite its attractive dial.
