The Longines Elegant Collection L4.309.5.89.7 watch has a sturdy stainless steel case and a pretty pink mother-of-pearl dial. It's powered by a self-winding movement with central seconds, known as caliber L592.2 (but sometimes also called L592 or L595). You can catch a glimpse of the movement through the transparent case back. And for a touch of elegance, the case and bracelet have a rose gold finish on certain parts.
