What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Fortis Flieger F-43 Bicompax

Owners widely praise the Fortis Original for its tool-watch aesthetic, legibility, and robust construction, with many noting excellent lume that lasts all night and precise day/date changes at midnight. The brushed stainless steel case is well-finished, and the 38mm size is considered comfortable and well-weighted despite being smaller than modern watches. Accuracy figures range from +2 seconds/day to +8 seconds/day, and some owners compare Fortis quality favorably to Omega. However, some users find the MSRP too high compared to brands like Sinn and Damasko, and one owner reported internal parts dislodging from a limited edition model. Concerns have also been raised about stripped lug screws on B-42 models and potential parts shortages due to past bankruptcy protection filings. Overall, owners rate the Fortis Original highly for its durable construction and tool-watch functionality at a competitive price point.

Longines LA GRANDE CLASSIQUE DE LONGINES

Owners widely praise the La Grande Classique de Longines for its extreme thinness, elegance, and timeless simplicity, with many finding it comfortable and lightweight due to its slim, flat design. The quartz version is recommended for its accuracy and convenience, while both quartz and automatic models are noted for their slim profiles and elegant aesthetics, with the bracelet being comfortable. Some owners are split on the styling, with Roman numerals appealing to some but not all, and one owner finds the Tonneau collection model a lovely dress watch despite preferring round faces. Owners suggest pre-owned options for better value, with prices ranging from $300-$1000 USD depending on the model and condition. One owner reports frequent battery replacements on the quartz model, with batteries lasting only months. Overall, owners rate the La Grande Classique de Longines highly for its slim, elegant design and value, particularly on the pre-owned market.
