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.

Phoibos Reef Master

Owners widely praise the Phoibos Reef Master for its exceptional value, highlighting its sapphire crystal, DLC coating, and extensive BGW9 lume. The watch is noted for its cool lume, with one owner finding it not bulky despite its robust build. The Shamrock Green dial and texture are highly praised, as is the comfortable bracelet with solid end links. However, the bezel action is described as rough, and the basic folding clasp is a disappointment. Accuracy is reported as excellent, with one owner seeing +-2 sec/day. Some find the 42mm size almost too big for their wrists, and the date window is considered too small. Overall, owners rate the Phoibos Reef Master highly for its impressive feature set and value at its price point.
