Sugess Tourbillon Master SUEARTHvsYema Flygraf Bi-Compax French Air Force

Owners praise the Sugess Tourbillon Master SUEARTH for its legible dial and the visual appeal of its beating tourbillon, offering an accessible entry into tourbillon watches. However, the strap and buckle are noted as comically large, and the screw-down crown and winding stem are described as flimsy. Some owners question the value proposition, finding the price high for the perceived quality, and express concerns about long-term durability and serviceability of the ST8230 movement. On balance, owners find the Sugess Tourbillon Master SUEARTH to be a functional tourbillon that works as intended, though its value is debated among the community.

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.
