Our Thoughts
Much of our coverage on IWC Schaffhausen has centred on their Pilot’s Watches collection – watches evoking jet cockpit instruments, and appropriate for both aviators as well as motorsports. We have also covered the brand’s Ingenieur and Portugieser collections. Recently the brand has been basking in the spotlight of the newly released F1 The Movie starring Brad Pitt. (Great movie, a must watch.)
The Portofino collection – named after the town on the Italian Riveria – is the brand’s interpretation of versatile dress watches. “Notable for its freshness and purity,” watches in this collection are suited for luxurious daily wear, both casual and formal.
“For over 30 years, the classically elegant Portofino has captured the laid-back lifestyle of the Mediterranean and the very essence of understatement and good taste.”

Though the brand describes the Portofino Automatic Day and Night 34 as a ladies’ watch, I believe it might appeal to men as well. Unisex watches is a trend I noticed during Watches and Wonders Geneva 2025. A. Lange & Söhne unveiled its classic 1815 in a 34 mm case size, one of the most talked about watches this year. Senior executives at Patek Philippe insisted that their new Twenty~4 Perpetual Calendar is a unisex watch. The Twenty~4 is a ladies’ collection.
The Portofino Day and Night 34 with its silver-plated dial and 18K 5N gold case highlights IWC Schaffhausen’s elegant and romantic side. It’s day and night display serves as a reminder to enjoy life’s moment and not always be in a hurry.
