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.

Spinnaker Hass Automatic

The Spinnaker Hass Automatic is a 43mm watch featuring an NH35 movement and sapphire crystal, with owners highlighting its beautiful dial. Some find Spinnaker watches, including this model, to be on the thicker side, with one owner describing the Hass X MCS Blue Fade variant as comically large and chunky. The Spinnaker Hass Automatic was offered at $445 USD as part of a special collection with customized elements, and a limited edition of 200 pieces was also available for $195 shipped. On balance, owners and reviewers note the attractive dial as a key positive, though some express reservations about the watch's thickness.
