My GADA watch. Size wise it is perfect. Diameter, lug to lug, etc perfect for a 6.5 inch wrist. I have it on the H-link bracelet and it is comfortable and fits well. The Mother of Pearl dial is out of this world. Many MOP dial watches you see it's very in your face with the color changes. Not the Sinn. The color change is very subtle meaning for the most part the dial is black/dark grey. When you view it at the right angle in the light and bam... my only complaint is the ghost date (watch has no date on dial but movement has a date complication).
