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.

Spinnaker Croft 39 GMT

Owners praise the Spinnaker Croft 39 GMT for its colorful design, NH34 GMT movement, and reasonable price, noting high-standard manufacturing on the case, bezel, and bracelet. One owner finds the 43mm case and 51mm lug-to-lug dimensions too large for the design, preferring a 39-40mm case size. A potential issue with the lume was noted by one user. On balance, owners value the Spinnaker Croft 39 GMT for its attractive design and build quality at its price point, though sizing is a point of contention for some.
