What people say

Owners + reviewers, side by side

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

Seestern Sub 300 V4

Owners widely praise the Seestern Sub 300 V4 for its terrific fit and finish and surprising little touches at its $179 price, noting top-notch case, dial, bezel, and crystal. The bracelet is considered nice enough for the price point, and the watch is powered by the solid and reliable Seiko NH35 movement. Some owners report that the polished sides of the case show signs of wear. Overall, owners rate the Seestern Sub 300 V4 highly for its excellent case, dial, and bezel finishing at the price.

Glycine Airman GMT

Owners widely appreciate the Glycine Airman GMT's ability to track three time zones, with some finding the 42mm size appropriate for its functionality. A reviewer notes the polished GMT hand can be difficult to read and lacks lume, while one owner reported an ETA movement with a misaligned GMT hand. Another owner finds the lume pips weaker than the hands.
