Reviews

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

Islander 43mm Automatic Dual-Time

Owners widely praise the quality and comfort of Islander bracelets, particularly the Jubilee and Oyster styles, noting their solid construction and ease of adjustment for the price. One owner specifically highlighted the good quality of the BRAC-05 bracelet with its solid curved end links and screw pins. On balance, owners rate the Islander 43mm Automatic Dual-Time Watch #ISL-50 highly for its excellent value and comfortable, well-made bracelets.

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.
