Citizen Series 8 890vsSugess Seakors Tourbillon SE8007

The Citizen Series 8 890 is praised for its robust build, 200 meters of water resistance without a screw-down crown, and excellent case finishing for its price. Reviewers note the smooth action of its internal bezel, though one suggests the knurling could be more pronounced for better grip. It utilizes the caliber 9051 automatic movement with a 42-hour power reserve, which often performs better than Citizen's stated -10/+20 seconds per day. The watch's design is noted as borrowing from popular luxury sports watches, and its lug-to-lug measurement can make it wear large. Overall, reviewers find the Citizen Series 8 890 a compelling and robust sports watch, particularly for its finishing and water resistance capabilities.

Owners widely praise the Sugess Seakors Tourbillon for its attractive dial and case finishing, along with the value offered by its functional flying tourbillon. One owner reports the Seagull ST8007 movement is reliable, running at -2s/day or +5s/day. However, the 24-hour complication is considered questionable, and some dust and oil are visible under magnification. With 5ATM water resistance and no lume, it is not suited for demanding activities. On balance, owners rate the Sugess Seakors Tourbillon highly for its impressive tourbillon complication and design at its price point.
