What people say

Owners + reviewers, side by side

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

Longines MASTER COLLECTION CHRONO MOONPHASE

Owners widely praise the Longines MASTER COLLECTION CHRONO MOONPHASE for its mesmerizing dial and value, offering numerous complications at its price point. However, its 3 bar water resistance limits wearability, and some find the dial busy with the chronograph hour pointer obscuring the moonphase. One owner noted it is a "thick boi" and the blue is less vibrant than pictured, while another mentioned scuffs on the case and discrepancies with the rotor weight and column wheel compared to the website. The consensus is that the Longines MASTER COLLECTION CHRONO MOONPHASE is a gorgeous, high-horology offering for its price, despite some functional limitations and aesthetic critiques.

Yema Flygraf Bi-Compax French Air Force

Owners widely praise the Yema Flygraf Bi-Compax French Air Force for its attractive, toolish aesthetic and excellent quality for the price, noting the legible Type A dial and 40mm titanium case. However, the acrylic crystal scratches easily, and the titanium case is prone to marking. The mecha-quartz movement's chrono timer sweeps rather than ticks, and one owner questions the purpose of the oversized crown. The in-house Yema 2000 movement is accurate at +/- 10 seconds per day but has a 42-hour power reserve, and some owners express concerns regarding Yema's past quality control and customer service. On balance, owners rate the Yema Flygraf Bi-Compax French Air Force highly for its attractive design and value, despite concerns about material durability and brand service history.
