this is a rare IWC Ingenieur perpetual calendar from the 1990s in 18k yellowgold. It´s beautiful 35mm case is in absolutely awesome shape with almost no signs of wearing. It comes with it´s original box, an IWC service card from 2000 and the user manual on spanisch, italian and french, the original unworn iwc leatherband with iwc 18k buckle and a second leatherband in addition. The watch was fully serviced a few months ago by the original owner and is working propperly i all functions. The beautiful white enamel dial is in great original condition with a few little hairline cracks in the first layer of paint (usual effect for this vintage reference) and all tritium dots still being there. A complicating neovintage collectors watch with a beautiful gerald genta inspired design.
