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 high-quality finishing on the Oystersteel case and bracelet, exceptional dial legibility with bright Chromalight lume, and the versatility offered by various color schemes and models like the "Sprite," "Root Beer," "Pepsi," "Batman," and "Batgirl." Some owners consider specific references, such as the all-black 116710LN, to be the best stainless steel GMT ever made or a great value. The watch is noted for its GMT function and thinner case profile, with accuracy reported around -2/+2 seconds per day by one owner. However, some find the ceramic bezel lacks satisfying clicks, and one owner dislikes the green GMT hand and text against the black dial, along with the bezel text font and polished center links. Acquiring a GMT-Master II from an authorized dealer is challenging, with significant wait times.

From video reviewers

The two-tone black and brown Cerachrom bezel offers a novel and contemporary aesthetic. Reviewers suggest buyers verify lug-to-lug measurements and compare bracelet comfort against full-steel alternatives due to the mixed-metal construction.
