IWC Schaffhausen Portofino Dual Time (Ref. 3610)

The new IWC Portofino Dual Time watch (Ref. 3610) is the ideal choice for globetrotters or frequent flyers. Time zones can be changed and the date reset simply via the crown.

The 24-hour display, discreetly positioned in the upper half of the dial, reliably informs the wearer of the correct time back home. A red hand completes a full revolution once a day, while the index markers and imprinted figures show the time from 0 to 24 hours.

Local time is displayed conventionally on the hour and minute hands. It is set using the crown, which first needs to be pulled out to position 1. The hour hand can then be advanced or turned back in one-hour steps. If in the process the hour hand moves into another day, the date at the destination in question is likewise adjusted, either forwards or backwards. Two barrels ensure a power reserve of 72 hours when the watch is fully wound.

Inside the watch beats the new 64710 calibre, manufactured exclusively for IWC by MHVF (Manufacture Horlogère ValFleurier). A bidirectional pawl-winding system starts transmitting energy to the barrels as soon as the wearer moves his arm. The rotor with the engraving “Probus Scafusia” – “Good, solid craftsmanship from Schaffhausen” – and the exquisitely finished movement can be viewed through the transparent sapphire-glass back.

As befitting a watch of its class, the superb movement is housed in a typically elegant, Portofino-style case measuring 45 millimetres in diameter. The Portofino Dual Time is available in a fabulous solid red gold case with a black dial and red gold indices and numerals or in simple stainless steel with a choice of either a black or a silver-plated dial.

In the red gold version the characteristic indices and numerals are likewise made of solid gold. The arched-edge sapphire glass has an antireflective coating on both sides and sets off the lightness and elegance of the watch to perfection.

The hand-dyed leather straps in black or dark brown underscore the Italian-style delicacy of touch typical of the Portofino family. A discreet pin buckle or a slim folding clasp elegantly rounds off the overall picture.
