This is a heavy clamper with a tight spring and it fits a 6.5 to 7in. wrist quite nicely. The design #5316 is a book piece and it is shown with the identical design necklace with charm. The necklace is listed separately on my site. The face of the piece is 2.5in. tall and it weighs a heavy 100.9 grams. This in your hands has a wonderful textured appeal and is much more striking than the pictures show. Collector quality.
