What people say

Owners + reviewers, side by side

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

Redux Zero-Hour

Owners widely praise the Redux Courg Zero Hour 39MM for its robust, utilitarian design inspired by pilot and dive tools, its lightweight Grade 5 titanium construction, and its comfortable wearability. The proprietary RDXB1 lume is noted for its bright initial glow, though it fades quickly. The Seiko NH53A or NH35 movement is generally considered reliable. However, multiple owners report a flimsy or fragile crown stem, and some describe the unidirectional bezel as having play or being able to rotate clockwise by one minute, though one owner reported a tight bezel with no play. The 39mm case size is considered good by some, while others find it small for larger wrists or note it looks large, with some desiring a 42mm option. One owner found the titanium finish looked slightly cheap and wished for a bezel insert. The dial is described by one owner as too busy for easy reading without glasses. The Redux Courg Zero Hour 39MM is available for $300, down from an original price of $507.

Zelos Artemis

The watch's unique modular case construction with a sandblasted titanium outer case and a grey/white Cerakote coating on the center is a notable strength. The FKM rubber strap can be prone to a slight rattle, which may be a minor annoyance for some owners. Reviewers disagree on the watch's value proposition, with one reviewer questioning its value for collectors.
