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's finishing, legibility, and versatility, with many citing the ceramic bezel's scratch resistance and the excellent Chromalight lume. The Oystersteel case and bracelet are generally well-finished, featuring a comfortable taper and secure clasp, though some note the steel is softer than standard. The GMT function is appreciated for travel, and specific configurations like the "Batman" (BLNR) and "Pepsi" (BLRO) are frequently favored for their aesthetics. One reviewer finds the steel "Pepsi" model sustains its appeal due to the harmonious integration of case, bezel, and Jubilee bracelet. The bidirectional bezel action is described by one owner as lacking satisfying clicks. Acquiring popular steel models at retail can involve wait times exceeding 12-24 months. Overall, owners rate the Rolex GMT-Master II highly for its blend of sport and dress appeal, with specific colorways and the Jubilee bracelet often highlighted as key strengths.

From video reviewers

The GMT-Master II "Root Beer" features a distinctive black and brown Cerachrom bezel and GMT complication. Reviewers did not agree on any weaknesses.
