What people say

Owners + reviewers, side by side

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

Tornek-Rayville TR-660 Aluminum Non-date

Owners praise the Tornek-Rayville TR-660 Aluminum Non-date for its crisp dial and bead-blasted case, with one owner finding it extremely well built and a relief to wear. The watch features a 40mm 316L stainless steel case and a black aluminum bezel inlay. However, the bezel action is considered not brilliant and the included straps are scratchy. Overall, owners find the Tornek-Rayville TR-660 Aluminum Non-date to be a well-executed piece with a pleasing aesthetic, despite minor drawbacks in the bezel feel and strap quality.

Zelos Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
