Glycine Combat Sub Box CeramicvsIslander Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300

Owners widely praise the Glycine Combat Sub Box Ceramic for its exceptional thinness at 10.4mm for a 42mm diver, perfect proportions for small wrists, and unique, non-homage aesthetic, with some considering it the best dive watch under $400 due to its superior finishing and value. The case shape, dimensions, and drilled lugs are also highlighted as positives, and the dial is legible with good lume on the hands. However, reviewers and owners consistently flag sub-par lume on the markers that fades quickly, and an inconsistent power reserve. Some owners report the stock strap or bracelet is subpar, and one owner experienced the bezel detaching after a light bump, questioning build quality. Accuracy figures vary, with one owner noting it runs about 2.5 seconds fast per day, while another reports an inconsistent power reserve. On balance, owners rate the Glycine Combat Sub Box Ceramic highly for its thinness, unique design, and value, despite concerns about lume and strap quality.

The Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 is praised for its 39mm size and comfortable fit, with its bi-directional dual time bezel noted as a useful feature for tracking different time zones. Owners appreciate the lumed ceramic bezel and the slightly domed sapphire crystal. One owner specifically highlights the dial layout as a strong positive. The screw-down crown is also mentioned as a nice touch. On balance, owners rate the Islander Greenport 39mm Dive Watch with Black and White Dial #ISL-300 highly for its wearability and functional bezel.
