What people say

Owners + reviewers, side by side

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

AVI-8 Flyboy Airmaster GMT Automatic

Owners widely praise the AVI-8 Flyboy Airmaster GMT Automatic for its robust build quality, intricate three-timezone function, and crisp dial texture. The watch is noted for its wearable 41mm case size and 48.5mm lug-to-lug, with an internally positioned GMT complication that maintains a clean dial appearance. Some owners report the stock leather strap feels cheap and limits strap changing options. On balance, owners rate the AVI-8 Flyboy Airmaster GMT Automatic highly for its solid finishing and value, particularly highlighting the dial's depth and texture.

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.
