Ingenious Porsche Design utility. This International Watch Co. Porsche Design compass watch blends precision engineering with the kind of clever functionality collectors love. Our present IWC Porsche Design with the reference IW3510 features a black dial and a fun integrated compass function giving it a distinctly technical, adventure-ready character. Using the pushers on the side of the lugs activates the clever mechanism, lifting the watch head to reveal the hidden compass beneath. Its 38mm PVD-coated aluminium case wears charismatically and light on the wrist. Inside beats the IWC calibre 375 automatic movement. It has been thoroughly inspected by our watchmaker, is fully functioning and keeping good time. To give collectors peace of mind we provide a 1 year mechanical warranty. Our boutique is located in Mayfair London, United Kingdom. All of our current inventory is available to view in store Monday to Friday from 11am to 5pm. All of our watches are authenticated by vintage watch experts and we stand by every product we sell. We ship worldwide and are at your service for any assistance you require.
