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 Acrylic Non-date

The Tornek-Rayville TR-660 Acrylic Non-date is a 40mm bead-blasted stainless steel watch with a utilitarian matte black dial and a moisture detector, measuring 14.7mm thick and 48.5mm lug-to-lug, featuring a subtly domed, AR-coated crystal. One owner notes a preference for a different watch's bezel-locking mechanism but appreciates the TR-660's 20mm lug size. Another owner reports damage to the case and bezel, though it includes unused and worn straps. On balance, owners find the Tornek-Rayville TR-660 Acrylic Non-date to have a timeless design that remains appealing.

Zelos Mako 4

Owners widely praise Zelos' dial finishing, with specific admiration for blued markers and hands, and the unique titanium bezel insert. Reviewers highlight the Mako 4's impressive case finishing and fully lumed ceramic bezel for its price point, noting the boxed sapphire crystal and wavy dial texture contribute to a vintage feel. The Sellita SW200 movement is described as reliable, with one owner reporting accuracy of -0.3 seconds per day. However, the crown can be difficult to grip, and the winding mechanism offers resistance when screwing down, while the watch's height may hinder wearability under a suit cuff. The tropic rubber strap is considered excellent, in contrast to a stiff leather option. On balance, owners and reviewers rate the Zelos Mako 4 highly for its exceptional dial and case finishing at its price point.
