You might need to use Samsung Pay, Since Google pay wasn't supported in that time, Try using Samsung pay in your watch.
(Depends on what watch you have, You can set up Samsung Pay in the wearable app you are using, If it's and older version, I might be afraid it won't be supported)
Thanks for the response and I do have samsung pay but it's weird every time I try and use samsung pay on my watch it will not come up when I hold the back button. My phone is a a 13 it's up to date and so is the watch also Uninstalled and reinstalled galaxy plug-in also any suggestions would be appreciated please and thanks!?
Thank you for reaching out. I can certainly understand your concern with not being able to use Samsung pay on your Galaxy watch and Galaxy A13. I am also seeing you are wanting to know if you can use Google Pay or Google Wallet on your original Galaxy watch. Google Pay is not compatible with the original Galaxy watch as it does not run WearOS software. The original Galaxy watch uses Tizen based software. Please give this link a try for more information on Google Pay compatibility: https://developers.google.com/pay/issuers/overview/supported-devices
