Sugess Tourbillon Master SU8001vsLongines LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Sugess Tourbillon Master for its accessible tourbillon complication and value, with one owner noting an initial accuracy of +2 seconds per day. However, community feedback flags a winding stem that feels flimsy and straps that are considered poor, featuring a comically large buckle. Some owners report a degradation in accuracy to around -20 seconds per day after a month, and the steel case edges are described as rounded with the material proving soft and prone to scratching. On balance, owners view the Sugess Tourbillon Master as a remarkable value for its tourbillon feature, despite concerns regarding strap quality and long-term material durability.

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
