6 Diamonds white 10KT Rolled Gold Plate, 23 Jewel 5AT. Facetted crystal.
Supporting linebook and advert shows the model as 'Lady Petite', but only mentions the yellow gold version, marked as "J" variant. Note this watch is NOT the "J" variant.
Movement is stamped M8. Unknown if it is original or not, but nothing to suggest that is it not.
