Ladies’ Tourbillon RM 019 “Celtic Knot”

Tourbillon RM 019 by Richar Mille

For 2009, a long awaited addition to the ladies’ collection at Richard Mile watches has become a reality with the presentation of the RM 019 “Celtic Knot” Ladies’ Tourbillon wristwatch.

Dating back to about the 5th century, the most emblematic and identifiable artwork in Celtic history is the Celtic knot. This symbol, also referred to as the mystic or endless knot, suggests that in life there are neither beginnings nor endings, consequently reminding us of the timeless nature of the spirit. With its unlimited pathway, the Celtic knot symbolizes an uninterrupted life; it is an emblem of longevity and the never-ending cycle of our existence.
