What people say

Owners + reviewers, side by side

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

Nivada Grenchen F77 MK2 38mm Automatic

Owners widely praise the Nivada Grenchen F77 MK2 38mm Automatic for its excellent wearability, with its 38mm size and comfortable, flat-laying case and downturned lugs fitting well on smaller wrists. Reviewers and owners alike highlight its slick fit and finish, unique dial options including Lapis, and strong value proposition as an integrated bracelet watch. One owner notes the Soprod P024 automatic movement offers solid performance. Overall, owners and reviewers rate the Nivada Grenchen F77 MK2 38mm Automatic highly for its comfortable wearability and unique dial aesthetics at its price point.

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.
