@Peter-Pan-0 It should all still be on the watch. You can check by going to the Logbook. If it has all the stats just like the activity summary screen, especially the graphs (HR, zone chart, elevation profile), then all the data should still be on the watch. If it only shows a small summary of distance and time, then the full dataset is not on the watch. Activities are deleted from oldest to newest to free up room when necessary.
I’ve had to recover activities stored on the watch before and it isn’t totally straight forward. I think the process goes something like this:
Delete the activity from SA
Unpair watch from SA and remove SA connection from watch (Settings > Connectivity > Paired devices > MobileApp)
Remove watch from phone’s BT connection
Sign out of SA (this removes an activity data saved to the device)
Close SA (you can go one step further and delete/redownload SA, but I don’t know if that’s necessary)
Open and sign back in to SA
Re-pair watch
When the watch is re-paired, SA will look for any stored activities on the watch that are not already attached to your account.
Honestly, all you might need to do is delete the activity and then sign out and back in to SA. The above just covers all the bases.
I’ll stress that this has worked for me in the past, but, obviously, make sure you save a backup of the activity before you delete it! Either directly from the Suunto App or from another connected service. If, for some reason, the above doesn’t work, there are ways to get the .FIT file back on to your Suunto account, although that’s not straight forward either.
