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.

Seestern S456 GMT

Owners widely praise the Seestern S456 GMT for its exceptional value and finishing that exceeds expectations, with one owner noting its accuracy surpasses that of their Seiko 5. The dial displays a pearl-like rainbow effect. Some owners would prefer a bidirectional bezel over the current unidirectional one. The Seestern S456 GMT features an NH34 movement, a 39.5mm case, sapphire crystal, and an adjustable clasp. On balance, owners rate the Seestern S456 GMT highly for its impressive finishing and value proposition at its price point.

From video reviewers

The watch features stunning, detailed finishing that is difficult to top. Reviewers did not reach a consensus on any weaknesses.
