Found on some knockoff Panerai watches (Add your watch to the comments below…)

The Hangzhou caliber 2C10 is an dual subdial automatic watch movement with a small running seconds indicator on the left and a power reserve indicator on the right.

Hangzhou 2C10 VS 2C30:

There is a similar caliber 2C30 – both movements have a power reserve indicator and date, but the main difference is that the 2C10 being discussed here has a small seconds subdial at 9:00 and the 2C30 has a central sweeping seconds hand.

Unconfirmed:

Most of the information on this caliber is unconfirmed and may need updated. Good luck finding any technical information! Even the sellers that offer raw HZ 2C30 movements for sale, usually don’t provide any important specs such as diameter, height, hand sizes, etc. You will most likely find this movement in watches that are already assembled. You may get the watch and find that there is no caliber designation (nor a jewel count, factory name, country of origin).

Replacement Prices:

While you can get raw movements of the 2C30 variation, the 2C10 movement does not appear to be available yet for individual sale. It has shown up in some of the knockoff watches (eg: IWC, Panerai style pieces) released in 2022-2023.

Even if you find a seller offering the 2C10, keep in mind that there is rarely a seller that has these movements on-hand and ready to ship outside of China, so expect to wait. Even if you find an eBay seller that claims the item is located in USA, be aware that there are many China based eBay sellers putting USA as the item location but still shipping from China to a USA shipping fulfillment center. What this means is that you most likely won’t be getting your package in 2-3 days.
