What people say

Owners + reviewers, side by side

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

Glycine Combat Sub Sport

Owners widely praise the Glycine Combat Sub Sport for its exceptional thinness, with multiple sources noting profiles between 10.4mm and 11mm, comfortable wearability on a variety of wrist sizes due to its proportions and contoured lugs, and its value, especially when found under $400. Some owners highlight its refined finishing and unique, non-homage design, while others appreciate its ruggedness and durability, with one noting PVD coating remained flawless after three years of heavy use. Accuracy figures range from excellent, with one owner reporting only 2 seconds lost per day, to inconsistent power reserve and occasional reported issues with the movement and stem. The lume is described as subpar by some, though one owner found it marginally better than a Seiko SKX007. Reservations are occasionally raised regarding warranty service and the use of folded end links on the bracelet.

Longines HYDROCONQUEST GMT

Owners widely praise the Longines HYDROCONQUEST GMT for its excellent finishing, smooth winding action, and overall value, with some finding its build quality and colorways superior to higher-priced competitors. Reviewers and owners alike note its robustness as a traveler's dive watch with a true GMT movement. Some owners find the round markers at 6 and 9 disrupt dial symmetry, and the GMT hour markers are described as tiny and difficult to read. The date wheel can be mismatched on certain dial colors, and the bracelet clasp is noted as sharp by one reviewer. While some owners wish for a smaller case size, others find the 41mm comfortable. The bezel action is flagged as having bounce-back by one owner, though the brushed finish effectively hides wear. Overall, owners and reviewers rate the Longines HYDROCONQUEST GMT highly for its robust build and excellent value proposition.
