What people say

Owners + reviewers, side by side

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

Phoibos Voyager

Owners widely praise the Phoibos Voyager for its attractive MOP dial and good overall finishing, along with its fun octopus logo. However, reviewers and owners alike note that the red lettering on the red date wheel is illegible, and one owner reports the 13.5mm thick case can be prone to accidental knocks. On balance, owners rate the Phoibos Voyager highly for its attractive dial and finishing at the price point.

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.
