BRANDS: Tianjin
The Tianjin TY2800 family consists of automatic movements that are similar in design to the Miyota 8200 family. These are commonly used as-is in budget automatic watches and as ebauches for further finishing, decoration, and complications on more expensive models. The basic components have also been remanufactured and finished in Switzerland, earning them a Swiss Made label despite the engineering and basic construction origin.
Like the Cal. 8200 family, the ST16 movements feature indirect drive for the seconds hand. This gives them a characteristic “stuttering” seconds hand when moved suddenly.
