Unworn IWC Portofino Hand Wound Eight Days, Stainless Steel, 45mm, Ref# IW510106, box and papers

Introducing the unworn IWC Portofino Hand-Wound Eight Days Ref# IW510106 is a refined statement of classic watchmaking, marrying elegance with remarkable endurance. Housed in a polished 45mm stainless steel round case with a slim 12mm profile, it presents a captivating metallic blue dial that radiates depth and sophistication. Polished steel leaf-shaped hour and minute hands glide gracefully over applied indices and Roman numeral hour markers, while a crisp white minute and seconds track with Arabic numerals at five-minute intervals ensures precision at a glance. The dial’s balanced layout features a small second’s sub-dial and a power reserve indicator—both thoughtfully positioned for symmetry—alongside a discreet date display at 3 o’clock. Beneath the sapphire crystal with double-sided anti-reflective coating lies the IWC Caliber 59210 manual-wind movement, beating at 28,800 vph with 30 jewels. It delivers an extraordinary eight-day power reserve, deliberately capped from its full nine-day capacity to maintain optimal accuracy by avoiding diminished mainspring torque. A transparent case back offers an unimpeded view of the finely finished movement, while the black alligator leather strap from Italian artisan Santoni, secured with a stainless steel tang buckle, ensures luxurious comfort. Water-resistant to 30 meters, this Portofino is the epitome of understated glamour, built for those who appreciate both enduring beauty and mechanical mastery.
