Seiko 5 Sports SKX series

Owners widely praise the Seiko 5 Sports SKX series for its iconic dive watch design, robust build, and excellent value, with many appreciating its timeless styling and tool-like character. The movement, while basic, is noted as offering hacking and hand-winding capabilities, and accuracy varies, with many owners reporting +/-5 to 10 seconds per day despite the movement's potential for +/-40 seconds. Some owners find the original SKX models heavier and bulkier than newer iterations, while others critique the lack of a screw-down crown and ISO rating on the newer Seiko 5 Sports SKX series, deeming it less of a serious tool watch. Overall, owners rate the Seiko 5 Sports SKX series highly for its enduring design and value proposition as a robust, everyday watch.

Zelos Thresher 44

Owners widely praise the Zelos Thresher 44, with one owner noting its finish has proven remarkably scratch-resistant.

The Zelos Thresher 44 with an agate dial sold out in 90 seconds, with one owner receiving theirs and noting the bracelet was fully wrapped. Overall, owners rate the Zelos Thresher 44 highly for its desirability and scratch-resistant finish.
