Tianjin Seagull's three-hand date automatic from the ST21 family (also sold as TY2130), built on the ETA 2824-2 layout so it shares the 2824's dimensions and dial-feet positions (parts are not necessarily interchangeable). No Seagull spec sheet was found, so figures come from reference sites: 28,800 vph and 4.60mm height agree everywhere; diameter is 25.60mm per Grail Watch (Caliber Corner gives 26mm, likely the overall diameter). Not recorded because sources conflict: jewels (Grail Watch 26; Seagull retail pages 28; Caliber Corner unconfirmed 25/26/28) and power reserve (Grail Watch 42h; Caliber Corner about 40h; Seagull retail pages 39h or 42h). Hacking and hand winding are listed by both Grail Watch and Caliber Corner. Unlike the 2824-2 it is not offered in factory grades.
