Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Méraud Bonaire for its refined design, high-quality construction, and comfortable wearability, with many noting it feels slimmer and wears like a smaller watch. The bracelet is described as robust, well-made, and comfortable, not pulling hairs. Some reviewers highlight the applied markers and domed bezel as attractive design elements. Owners report significant manufacturing delays and communication issues with the brand, with watches ordered in late 2023/early 2024 not yet delivered past the original shipping window, leading to warnings about the risk of doing business with Méraud. On balance, owners and reviewers value the Méraud Bonaire for its wrist presence and build quality, though significant concerns exist regarding brand communication and delivery timelines.
Owners widely praise the Thorn SHY027 39mm BB58 Vintage Diver Automatic Watch for its authentic 1958 vintage aesthetic and compact 39mm case, which provides a vintage, old-school tool watch feel. The watch features Mercedes-style hands and a domed sapphire crystal. Some owners find the finishing and bracelet quality to be less refined than competitors, and the riveted bracelet is noted as difficult to adjust. One reviewer flags the lume as bright but short-lived. Overall, owners and reviewers rate the Thorn SHY027 39mm BB58 Vintage Diver Automatic Watch well for its vintage aesthetic and compact case proportions at its price point.
