Reviews

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Citizen Series 8 880 GMT

Owners praise the Citizen Series 8 880 GMT's refined, modern look and textured, snowflake-like dial. Reviewers note its striking gunmetal coating, gold-plated bezel, and true GMT movement. The watch features a 41mm case and 100m water resistance. One owner questions the price point, while another awaits a different colorway. The Miyota 9054 movement has a broad accuracy specification of -10/+20 seconds per day and a 50-hour power reserve. Overall, owners and reviewers appreciate the Citizen Series 8 880 GMT's distinctive design and GMT functionality, though some express reservations about its price.

Seiko 5 Sports SKX series

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.
