Reviews

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, often found under $400, its solid build with brushed finishing, and its notably thin case profile, with many sources citing dimensions around 10.4mm to 10.8mm, making it comfortable and wearable. Reviewers and owners consistently highlight its unique, non-homage aesthetic and excellent timekeeping, with some reporting accuracy within +1/+2 seconds per day, though one owner noted their Sellita SW200 movement ran at approximately +6 to +9 seconds per day. Some owners dislike the "COMBAT" text on the dial and find the lume sub-par, while others note inconsistent power reserve not always reaching the advertised 42 hours. On balance, owners and reviewers rate the Glycine Combat Sub Sport highly for its outstanding value and comfortable, thin wearability.

Serket Watch Co Reef X

Owners praise the Serket Watch Co Reef X for its tool-less bezel and bracelet swap system, allowing for frequent customization. One owner notes the watch looks great and matches images. The bezel is described as huge, comparable to the Marathon SAR. One owner found the receipt paper quality to be off. Overall, owners rate the Serket Watch Co Reef X highly for its customization features and aesthetic appeal.
