Here is a fabulous, all original IWC Portofino from 1997. The “Mark XII” style black dial is in excellent condition, with white lettering and barely any marks. It has white Arabic numeral hour markers with lume markers at the poles, a triangle at 12 o’clock. The baton hands are in very fine condition with the original lume intact. When the crown is pulled out to set the time or date, the hack feature stops the seconds hand so the time can be set precisely. The original sapphire crystal is in very fine condition. The black framed window at 3 o’clock displays the quick-set date. The quick-set function should only be used with the hour hand at the bottom half of the dial.

The stainless steel case with the original crown and elegant drop shaped lugs is in very fine condition with only light overall wear. The screwed down case back is in very fine condition with a brushed center and polished slope showing light overall wear. The case does not appear to ever have been polished.

The watch comes with the original IWC leather strap and buckle in fine condition.

Inside the watch, IWC’s version of the high grade ETA 2892-2 movement beats strongly and accurately to within about +-10 seconds per day. The watch was fully serviced in December 2025 and comes with a 12 month warranty on its proper mechanical functioning.

IWC is known for their timeless and elegant designs in affordable packaging, and this one is a good example of that. The black dial in the style of the iconic Mark XII made for the Roayl Air Force makes the watch look fabulous on the wrist and will make its next owner very happy indeed.

Our watches are delivered in a luxury wooden watch box, fully serviced with a 12 month warranty that covers the mechanical functioning of the watch under normal use. We offer 14 days full return rights and are very proud of our reputation for outstanding customer satisfaction.
