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.

Sternglas Naos XL

Owners widely praise the Sternglas Naos XL for its versatile Bauhaus design, domed sapphire crystal, and value, with some finding its larger size comfortable and refined for its price. However, opinions are split on its aesthetic appeal, with one owner finding the hands and face underwhelming, while others appreciate the minimalistic dial. The date font is noted as too small to be useful by one owner, and the stock strap is generally considered basic or prone to wear. Accuracy figures vary, with one owner reporting a Miyota movement running fast and another noting +13 seconds per day. Overall, owners rate the Sternglas Naos XL highly for its Bauhaus aesthetics and affordability, despite some reservations about the movement and strap.
