The IWC Portofino Day & Night (ref. IW6598-01) adds a poetic complication and refined sparkle to the classic Portofino silhouette. Introduced in 2022, this 34mm model is defined by its diamond‑set bezel and a serene sunray blue dial, punctuated by a day and night display at 6 o’clock – a quietly elegant touch in keeping with the collection's Mediterranean spirit.

Crafted in polished stainless steel, the case is complemented by a matching crown and slim lugs that ensure a graceful wrist presence. The dial’s contrast of crisp baton markers against the deep blue surface enhances legibility, while the automatic movement inside powers the hands and indicator with dependable precision. Water‑resistant to 50 metres, the Portofino IW6598‑01 is designed for both daily wear and occasional formality.

A rare combination of decorative detail and practical function in the sub‑36mm category, this reference underscores IWC’s growing focus on mechanical watches tailored to smaller wrist sizes, pairing aesthetics and performance without compromise.
