What people say

Owners + reviewers, side by side

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

Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18

Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18 owners praise its $300 value, noting the double-domed AR sapphire crystal and embossed ceramic bezel. The 43mm size is appreciated, and the NH36 movement offers hand-winding and hacking. On balance, owners rate the Islander Automatic Dive Watch with Bracelet, Double-Domed AR Sapphire Crystal, and Embossed Ceramic Bezel Insert #ISL-18 highly for its substantial feel and feature set at the price point.

Tissot Seastar 1000 Powermatic 80 GMT

Owners widely praise the Tissot Seastar 1000 Powermatic 80 GMT for its excellent build quality, smooth winding feel, and the reliable Powermatic 80 movement providing an 80-hour power reserve. Reviewers highlight its remarkable value under $700, comfortable wearability, and appealing case/dial ratio. Some owners note the bezel's functionality for tracking a second time zone and the need to adjust the hour hand for date setting, a characteristic of its "True" GMT function. The rubber strap is considered comparable to those found on significantly more expensive watches. However, concerns exist regarding the movement's serviceability due to potential plastic components and reliance on Swatch Group service centers. Some find the bezel font and dial spacing unappealing, while others question the mineral glass bezel insert as a cost-cutting measure compared to ceramic. Accuracy is generally reported as good, though not COSC certified, and lume intensity is described as average by one owner.
