What smart watch can be used to pay for purchases in Ukraine?

Question

Mobile devices

Interested in the real experience of people who use watches for contactless payment in Ukraine.
1) Is it possible to pay by the clock with nfc if there is no nfc in the phone itself?
2) Which watch manufacturers or operating systems support payment in Ukraine, for example, in conjunction with Privatbank? Are there budget models, or is payment possible only with gadgets in the $300-400+ price range (Apple, Samsung, etc.)?
