Hangzhou Watch Company 9 Series

The Hangzhou Watch Company's 9 Series (also designated 9000) is a manual-winding movement cloned from the ETA-Unitas 6497/6498, a large-format pocket watch caliber originally designed for oversized wristwatches. The movement remains in production and is available in skeleton, calendar, and dual-time variants. As a non-in-house caliber, it represents Hangzhou's replication of an established Swiss design rather than original manufacture.
