Why does my Apple Watch say Syncing with iPhone?

Time and trips you add on your watch are sent to your iPhone right away when it's nearby, or the next time they connect, and saved once WitnessWork runs on your iPhone. Until then your watch shows Syncing with iPhone. Its total and complications include that time right away, except Credit Time, which is added once your iPhone saves it and applies your monthly credit limit. Each entry keeps the day you added it on the watch, is saved only once even if it's sent again, and isn't brought back if you already deleted it on your iPhone. Saved entries reach your other devices with sync like any other entry. Starting, pausing, stopping and saving the timer need your iPhone nearby. If the watch says the timer changed on your iPhone, check the time and try again. If your iPhone can't save an entry, the watch tells you instead of confirming it, and the time isn't added; if it asks you to update WitnessWork on your iPhone, update it and try again. If your watch stays out of date, or its complications show — after a week without an update, keep your iPhone nearby and unlocked, open WitnessWork on your iPhone, then open it on your watch. After your iPhone restarts, unlock it once before syncing. For other problems, use the Help Center's private support link and keep your records out of public reports.
