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 S446 GMT

Owners widely praise the Seestern S446 GMT for its stunning finishing and extreme value, with a sapphire crystal and adjustable clasp. The winding action is noted as buttery smooth, and the 39.5mm case size is considered very wearable. Some owners, however, flag the lume as a weak point and one owner found the bracelet clasp lacked sufficient micro-adjustment. The Seestern S446 GMT is considered an extreme value for the dollar. Overall, owners rate the Seestern S446 GMT highly for its exceptional finishing and value proposition at its price point.
