This typically occurs with new old stock (NOS) watches, meaning the watch was sold by a retailer but never registered or activated, or remained in inventory without being officially stamped or dated. As a result, the watch was never put into warranty circulation, which is why the card remains blank. ⸻ Specifications • Brand: IWC Schaffhausen • Model: Portofino Day & Night • Reference: IW459101 • Movement: Automatic • Case Diameter: 37 mm • Case Material: Stainless steel • Bezel: Factory diamond-set • Dial: Mother of pearl with diamond markers • Functions: Hours, minutes, day & night indication • Strap: Blue strap • Buckle: Original IWC buckle • Crystal: Sapphire ⸻ Condition • Case & bezel: Very good condition • Dial & hands: Excellent • Movement: Functions well and keeps accurate time • Strap & buckle: Very good condition ⸻ Included • Original IWC box • Original IWC warranty card (not filled) • Original IWC cleaning cloth ⸻ Summary A beautiful and refined IWC Portofino Day & Night IW459101, offered in very good condition with box and accessories.
