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 Bronze

Owners report the Glycine Combat Sub Sport GMT Bronze offers a unique aesthetic and remarkable value, often found at significant discounts. One owner notes difficulty matching straps with the bronze dial and that seawater exposure can cause rapid, undesirable patina, suggesting regular cleaning mitigates issues. Another owner flags sub-par lume that is difficult to read at night and an inconsistent power reserve that may not reach the advertised 42 hours. On balance, owners value the Glycine Combat Sub Sport GMT Bronze for its unique aesthetic and strong value proposition, though lume and power reserve performance are noted concerns.

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.

From video reviewers

The 18k yellow gold construction is a notable strength. Reviewers did not reach a consensus on any weaknesses.
