You bet! It can be a little tricky getting it back, but not too hard.
First off, you need to measure sure that widgets are enabled for your lock screen - see the option in the lock screen settings found in under the display tab.
Next, put your phone to sleep then wake it back up to get to your lock screen.
Slide your finger right, starting at the left edge of the screen to reveal the add widgets screen. This essentially puts the phone into edit mode. Swipe back left to go back to the clock.
Press and hold the clock until you see the remove icon, then drag your finger to the remove icon and release to delete the clock.
You can add another clock by going back to the "add widgets" page and tapping the plus sign.
You can rearrange widgets by long pressing a widget and dragging left or right.
To get the circle clock back, you need to remove EVERY widget from the lock screen, then add them back.
Hope this helps
