Hello, DanPetro12.
Thank you for using Apple Support Communities.
It sounds like you're looking to manually lock your Apple Watch. If so, the steps below found in the article here will help: Lock or unlock Apple Watch
"Lock manually

- Touch and hold the bottom of the screen, then swipe up to open Control Center.
- Tap
.
Note: To manually lock your Apple Watch, you must turn off wrist detection. (Open the Settings app on your Apple Watch, tap Passcode, then turn off Wrist Detection.)
You must enter your passcode the next time you try to use your Apple Watch.
You can also lock your screen to avoid accidental taps during a workout. While using the Workout app on your Apple Watch, just swipe right, then tap Lock. When you start a swimming workout, your Apple Watch automatically locks the screen with Water Lock."
You can also test switching the digital crown to the other side when wearing your Apple Watch during these activities. The section "Switch wrists or Digital Crown orientation" here Change language and orientation on Apple Watch has steps to help.
Best.
