Tianjin Seagull's day-date automatic from the ST21 family (also sold as TY2100), which Grail Watch describes as similar in design to the ETA 2836-2, with central day and date wheels showing both at 3:00, instant day and date change with quick correction, hacking seconds and hand winding; in production since 2005. No Seagull spec sheet was found, so all figures (25.60mm, 5.05mm, 26 jewels, 41 hours, 28,800 vph) come from Grail Watch alone.
