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.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
