Chinese automatic GMT caliber (also written HZ6460; a 6460B version exists) with central hours, minutes, seconds and 24-hour GMT hand and a date at 3. No factory spec sheet from Hangzhou was found. Caliber Corner gives 11½ lignes (26mm), 5.65mm high, 25 jewels, 28,800 vph, about 40 hours, hacking, hand winding, quickset date and a bidirectionally winding rotor, and describes it as an ETA 2824-2 type built on Hangzhou's 6300 base with an added "office/caller" GMT (local hour hand fixed, GMT hand set independently); Watchdives' own movement guide confirms only automatic GMT at 28,800 vph and cites San Martin's SN0054G-F listing for 25 jewels, 40 hours and stop-seconds, and says the setting architecture isn't established. Diameter is left blank (26mm rounded vs 25.6mm for 11½ lignes) and accuracy is not published. Not a copy of the ETA 2893 GMT, so `clone_of` is left empty. Tier "mid", alongside other Chinese 2824-type calibers such as the PT5000.
