Correspondingly, how do I use maps on Apple Watch 3?
Open the Maps app on your Apple Watch. Tap Location, then tap the destination landmark or map pin. Scroll the location information until you see Directions, then choose walking, driving, transit, or cycling directions. When you're ready to go, tap a route, then follow the directions.
Subsequently, question is, how do I know if my Apple Watch 3 has GPS? For example, my Apple Watch's engraving reads “Series 3, 42mm Aluminium Case, GPS.” To know if your Apple Watch supports Cellular or not, look at the Digital Crown. If it has a red circle or a red dot on it, you're using the Cellular model.
