Sugess Seakors Tourbillon SE8007vsLongines LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Sugess Seakors Tourbillon for its attractive dial and case finishing, along with the value offered by its functional flying tourbillon. One owner reports the Seagull ST8007 movement is reliable, running at -2s/day or +5s/day. However, the 24-hour complication is considered questionable, and some dust and oil are visible under magnification. With 5ATM water resistance and no lume, it is not suited for demanding activities. On balance, owners rate the Sugess Seakors Tourbillon highly for its impressive tourbillon complication and design at its price point.

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.
