RM 67-01 Extra Flat

This watch maintains the fascination with extra flat creations by mixing extra flat watchmaking with the conventional automatic watches that have come to be considered as synonymous with the experience. Combining this kind of movement design with a sense of visual depth inside the movement. The considerable skeletonization included in the RM 67-01 Extra Flat serves as one significant approach for doing this.
