What people say

Owners + reviewers, side by side

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

Sternglas Hamburg Automatik

Owners praise the Sternglas Hamburg Automatik's handsome design and good build quality for the price. The watch features a gold PVD case and a matte blue dial with orange Super-LumiNova, and its 42mm diameter wears well due to a short lug-to-lug distance. The Miyota 8215 movement is accurate to -20/+40 seconds per day. On balance, reviewers and owners appreciate the Sternglas Hamburg Automatik for its unique design and value.

Redux Zero-Hour

Owners widely praise the Redux Courg Type 39MM for its robust, no-nonsense design and good overall quality, with a reliable Seiko NH53A movement keeping time well. The titanium case and crystal have shown scratch resistance, and the bezel action is described as tight by some. Reviewers note the proprietary RDXB1 or blue lume glows brilliantly, though briefly. Some owners flag the crown stem as flimsy and the unidirectional bezel as having some play. Overall, owners rate the Redux Courg Type 39MM highly for its functional tool-watch design and durable titanium construction.
