Longines MASTER COLLECTION CHRONOGRAPHvsYema Flygraf Bi-Compax French Air Force

Owners widely praise the Longines MASTER COLLECTION CHRONOGRAPH for its excellent fit and finish and classically styled, vintage theme. The 40mm model's dial is described as mesmerizing and legible, balancing class and complexity. One owner highlights the column-wheel chronograph and crown-set moonphase as exceptional for its price point, which was noted around $1700 USD. Accuracy varies, with one owner reporting +8 seconds per day, while another found the case finishing somewhat homogenous. The watch features a triple date complication and has a water resistance of 3 bar. On balance, owners rate the Longines MASTER COLLECTION CHRONOGRAPH highly for its value and refined aesthetics, particularly the chronograph and moonphase complications.

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.
