Reviews

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

Nivada Grenchen F77 SST MK2

The Nivada Grenchen F77 SST MK2 is lauded by reviewers for its comfortable 38mm case with downturned lugs and a slimmer profile, enhancing wearability and making it a strong integrated bracelet option at its price point. Owners appreciate its suitability for swimming due to a screw-down crown and find it wears comfortably, with some preferring it over other integrated bracelet watches. However, one owner reported poor quality including a clunky rotor, misaligned lume, and a crooked logo, while another found the brand logo unappealing. The gold-plated version was considered loud by one reviewer, and lume is absent on some variants. Prices range from €1,665 for the steel version to €1,865 for the gold-plated version. Overall, owners and reviewers rate the Nivada Grenchen F77 SST MK2 highly for its wearability and design at its price point, despite isolated quality concerns and aesthetic critiques.

Wolbrook JetFlyer Automatic Chronograph

Owners widely praise the Wolbrook JetFlyer Automatic Chronograph for its solid value, durable and reliable construction, and appealing visual design featuring a domed sapphire crystal and fully brushed finish. The case finishing is noted as very nice with great detailing on the bezel and dial, and the bezel action is described as great with accurate alignment. However, some owners report the watch feels top-heavy and wears larger than its 38mm case, with one noting a thickness of 14mm or 14.3mm. Timekeeping varied, with one owner experiencing degradation to +2 minutes per day after the first week. Overall, owners rate the Wolbrook JetFlyer Automatic Chronograph highly for its robust build and aesthetic appeal at its price point.
