What is known as a Triskele or Triune, a three-legged
symbol.

QVOCVNQVE IECERIS STABIT
Size, 30 mm.
I found the following on the web:
"The Motto Quocunque Jeceris Stabit, which translates literally
as whithersoever you throw it, it will stand, also continues
to feature on the Arms. This motto has been associated with the Isle
of Man since about 1300. It was, reportedly, in use before this date
by the MacLeods of Lewis as ancient Lords of the Isles of Scotland
which, after 1266, included the Isle of Man."
