Hello Shafarva,
Welcome to the Apple Support Communities.
We have some insight that we can provide you with; compliments of Apple. Check out the information on this page to learn how to use Zoom on your Apple Watch: Use Zoom on Apple Watch - Apple Support.
Controlling Zoom
Once you’ve turned on Zoom, you can perform these actions on your Apple Watch.
* Zoom in or out: Double-tap the Apple Watch display with two fingers.
* Tip: Double-tap with two fingers while setting up your Apple Watch to get a better look.
* Move around (pan): Drag the display with two fingers. You can also turn the Digital Crown to pan over the entire page, left-right and up-down. The small Zoom button that appears shows you where you are on the page.
* Use the Digital Crown normally instead of panning: Tap the display once with two fingers to switch between using the Digital Crown to pan and using the Digital Crown the way it works without Zoom on (for example, to scroll a list or zoom a map).
* Adjust magnification: Double-tap and hold with two fingers, then drag your fingers up or down on the display. To limit magnification, tap the plus or minus button on the Maximum Zoom Level slider.
We hope this information helps you out.
Kind regards!
