Reviews

Nivada Grenchen F77 SST Tuxedo MK2 38mm

The Nivada Grenchen F77 SST TUXEDO MK2 - 38MM is praised for its wearable 38mm stainless steel case, solid build quality, and commendable dial execution, with proportions that suit even larger wrists. Owners note its redesigned integrated bracelet with a tool-free micro-adjusting clasp. One owner reports the Soprod P024 automatic movement has a 38-hour power reserve. Another reviewer notes the F77 SST TUXEDO MK2 - 38MM has a 11.5mm case thickness. Some owners find the straight, flat lugs can hover above the wrist, though the lug-to-lug measurement is considered good. Overall, owners and reviewers find the Nivada Grenchen F77 SST TUXEDO MK2 - 38MM to be a well-built watch with good proportions, though opinions on lug comfort vary.

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.
