IWC PORTUGUESE .
ENGINEERED FOR NAVIGATORS.
Portuguese Chronograph Classic.
Ref. 3904: The fact that Portugal's greatest
seafarers are remembered to this day is
due not least to this watch: the appliquéd
Arabic
numerals and the railway track chap-
ter ring elegantly reference its legendar y
forerunner from the 1930s. But today's sea-
going pioneers are equally well equipped
with the Chronograph Classic. The IWC-
m a n u f a c t u r e d a u to m a ti c 8 9 3 61- c a l i b r e
movement and its 68-hour power reser ve
keep it firmly on course even under wind-
less conditions. Whether you're aboard a
historic
three-master or a modern motor
yacht, its state-of-the-ar t technology and
classic design soon make it clear who's giv-
ing
the orders. I WC . E N G I N E E R E D F O R M E N .
