This version features an 18-carat 5N gold case, a silver-plated dial, and gold-plated hands and appliques. On the dial, 12 diamonds mark the hours. At work inside is the IWC-manufactured 32111 calibre, which uses a bidirectional pawl winding system to build up a power reserve of 120 hours. A see-through sapphire glass back displays the movement, which has been finished with a gold-plated rotor and blued screws. This ladies’ watch is fitted with a beige strap made of fully traceable Swiss calf leather. The strap has a natural and soft finish and boasts a contemporary, luxurious feel. Thanks to the integrated quick-change system, the strap can be exchanged easily.
