Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing on the case and dial, COSC-certified L791.4 movement, and overall value as a flyback chronograph. Reviewers note its improved wearability due to a 47.4mm lug-to-lug distance and a thickness that, despite being listed as 17mm, wears closer to 13.5-14mm. However, the 17mm thickness is a significant drawback for some, making it difficult to wear under cuffs, and the leather strap is described as stiff. Owners are split on the dial's simplified look compared to previous models, with some preferring the earlier design elements. On balance, owners and reviewers rate the Longines Spirit Flyback Prototype highly for its refined finishing and value proposition, despite concerns regarding its case thickness.
