Longines LONGINES SPIRIT FLYBACK PROTOTYPEvsYema Navygraf FSM Bronze

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.

Owners praise the Yema Navygraf FSM Bronze for its wearable 38.5mm bronze case and comfortable, high-quality parachute strap. The in-house YEMA2000 movement is noted as a positive. The watch features a glossy black dial with elongated markers and hands coated in Super-LumiNova, powered by the YEMA2000 calibre with a 42-hour power reserve, regulated to -/+ 10 seconds per day. Overall, owners rate the Yema Navygraf FSM Bronze highly for its comfortable wearability and the quality of its strap and in-house movement.
