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 GMT

Owners widely praise the Glycine Combat Sub Sport GMT for its solid build, slim wearability, and value, with many noting its comfortable fit due to curved lugs and thin case. Reviewers highlight its classic design, unique dial, and legible date window, while some owners report excellent bezel action and accuracy under +1 second per day after regulation. A minor criticism is a slightly off-color lume pip on the chapter ring, and one owner notes sub-par lume and inconsistent power reserve not always reaching 42 hours. On balance, owners and reviewers rate the Glycine Combat Sub Sport GMT highly for its comfortable wearability and value at the price point.

Rolex GMT-Master II

Owners widely praise the Rolex GMT-Master II for its exceptional legibility, robust build, and comfortable bracelet taper, with many considering it the best stainless steel GMT ever made. Some find the two-tone variants a perfect balance between sports and dress, while others highlight the versatility of the "Batman" or the iconic status of the "Pepsi." The grey and black variant offers a more reserved aesthetic, and some owners view the all-black 116710LN as the best value buy. However, the bidirectional bezel's lack of satisfying clicks and the Oystersteel's proneness to scratching are noted drawbacks. Some owners find the green GMT hand and text difficult to see, and one owner considers it a downgrade from the Submariner due to its lack of quick-set date and lower water resistance. The Rolex GMT-Master II is difficult to obtain at retail, with wait times averaging 12-24 months.
