Formex Reef GMTvsSeiko Seiko 5 Sports SKX series

Owners and reviewers widely praise the Formex Reef GMT for its impressive specifications and value, highlighting its unique porthole case shape and comfortable quick-release bracelet with on-the-fly micro-adjustment. The COSC-certified Sellita SW330-2 movement is noted for good finishing and reliable timekeeping, with a 56-hour power reserve. However, the watch's overall width and lug-to-lug span, particularly with male endlinks, are frequently cited as being too large for smaller wrists. Some reviewers also find the bezel action stiff and slippery, and the GMT model lacks a timing bezel option with lume. Overall, owners and reviewers rate the Formex Reef GMT highly for its robust construction and excellent specs at its price point.

Owners widely praise the Seiko 5 Sports SKX series for its iconic, tough, and rugged dive watch design, timeless styling, and tool-like nature, with many finding its build quality and finishing superior to alternatives. The comfortable jubilee bracelet is frequently cited as a positive wearability feature. Accuracy with the 4R34 movement is a "luck of the draw," with specs allowing +/-40 seconds per day, though many owners report +/-5 to 10 seconds. Some owners experienced issues like scratched crystals, failed springbars, or misaligned bezels and hands. The Seiko 5 Sports SKX series is seen as a decent watch, readily available under £200, but not a serious tool watch like its predecessor due to lacking a screw-down crown, bezel pip, and ISO rating. Overall, owners rate the Seiko 5 Sports SKX series highly for its iconic design and value, despite some lacking modern features.
