Glycine Combat Sub SportvsSeiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition

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.

Owners widely praise the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition for its attractive, well-made design and gorgeous dial, noting its jewel-toned teal color and rippling-water pattern. The bezel action is smooth with a muted sound, and the case and bracelet offer a more comfortable feel than previous iterations. However, multiple owners express disappointment with the accuracy of the 6R movement at its price point, with some noting theirs runs slow, and consider the price too high. The steep rehaut and marker size make the 24-hour numbers difficult to read, and some find the case design makes the watch feel top-heavy despite wearing smaller. Overall, owners rate the Seiko Prospex Sea 1970 Heritage Diver's Black Series Limited Edition highly for its striking dial and refined case design, despite concerns regarding movement accuracy at its price.
