Introducing the IW356501: The Engine Behind the Classic IWC Portofino

The International Watch Company (IWC) has been a renowned luxury watch brand since 1868. Known for their precise engineering and timeless design, IWC watches have remained a favorite among enthusiasts in the horology community. Among their impressive collections, the Portofino stands out for its classic elegance and versatile style. The Portofino Automatic IW356501 in particular has become a staple in IWC's portfolio, and for good reason. At its heart is one of the most reliable and efficient engine, the in-house caliber 35111.

The Caliber 35111: A Tried-and-Tested Workhorse

The IWC Portofino IW356501 is powered by the caliber 35111, an automatic movement that is based on the ETA 2892-A2. IWC has made several modifications to the base movement, mainly for improved accuracy and reliability. One of these modifications is the incorporation of IWC's own Pellaton winding system, which uses a bi-directional rotor and ceramic ball bearings to maximize the energy transfer from the rotor to the mainspring. The result is a power reserve of 42 hours, which is more than enough for daily wear.

Another modification is the use of a higher quality hairspring. The original ETA version used a basic flat hairspring, while IWC's version uses a Breguet overcoil, which improves isochronism and reduces the effects of gravity on the balance. The balance itself has also been adjusted for more precise regulation, with a higher frequency of 28,800 beats per hour.

The Portofino Design: An Icon of Elegance and Simplicity

The IWC Portofino has always been known for its minimalist design, and the IW356501 is no exception. The 40mm case is slim and polished, with a height of only 9.5mm. The dial is a classic, clean white with Roman numerals and simple baton markers. The date window sits at 3 o'clock and is unobtrusive, adding a practical touch to the overall design. The hands are sleek and slender, with a touch of lume for readability in low light conditions. The case back is solid and boasts the Portofino logo and other information about the watch, including the fact that it is water-resistant to 30 meters.

The leather strap completes the look, adding to the classic and timeless appeal of the watch. The Portofino Automatic IW356501 is available in several strap options, including black, brown, and blue for a more modern look. The strap is secured by a simple pin buckle, which is unobtrusive and easy to use.
