What people say

Owners + reviewers, side by side

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

Marathon Arctic Steel Navigator

The Marathon Arctic Steel Navigator is praised for its pragmatic, no-nonsense design and comfortable wearability due to its thinner, ergonomic steel case. Owners and reviewers highlight its highly accurate ETA F06.412 quartz movement, which offers exceptional timekeeping and a seven-year battery life with a field-serviceable battery port. One owner reported their Arctic Steel Navigator's pip fell out shortly after unboxing, and the bezel later became gritty and hard to turn, though another owner found success cleaning their gritty bezel with soap and water. A reviewer noted a preference for a different strap design for a cleaner tail tuck. On balance, owners and reviewers rate the Marathon Arctic Steel Navigator highly for its pragmatic design and accurate, reliable quartz movement.

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.
