IWC Perpetual Calendar Ref. IW502213 – 18K Rose Gold – Full Set – Bj-2006 – IWC Service 02/2026 – Excellent

An impressive and highly sophisticated IWC Perpetual Calendar Ref. IW502213 in 18k rose gold, originally purchased in Hof, Germany, and freshly serviced by IWC in February 2026.

We are pleased to present this remarkable perpetual calendar, a model that exemplifies IWC’s mastery of high complications combined with technical clarity and everyday usability. Crafted in 18k rose gold, the case radiates warmth and presence while maintaining refined proportions suitable for both formal and distinguished daily wear.

The elegant silver dial offers outstanding legibility despite the complexity of its perpetual calendar display. The harmoniously arranged subdials present the date, day, month, year, and moon phase in a balanced and intuitive layout - an engineering achievement that automatically accounts for varying month lengths and leap years. The combination of the silver dial with the warm tone of the rose gold case creates a particularly sophisticated and timeless aesthetic.

This example underwent a comprehensive service at IWC in February 2026. During this major overhaul, the hands were replaced and the case was professionally refinished, ensuring both optimal technical performance and a beautifully refreshed appearance.

The watch is fitted with a brown crocodile leather strap and an 18k rose gold folding clasp, completing the luxurious and cohesive presentation on the wrist.

Originally sold in Hof, Germany, this piece is offered as a particularly complete set, including:

- Original presentation box

- warranty card, Germany 2009

- Microfiber cleaning cloth

- Warranty booklet

- Instruction manual

- Important operating instructions flyer

- Annual pusher (year corrector stylus)
