Iwc The AZ-produced International Portugal series calendar watch integrates hour and minute hands, date, day of the week, month, and a dynamic display all in one. As the saying goes, exceptional functionality takes time to mature. We invite watch enthusiasts from all walks of life to appreciate and support it.The watch case measures 44mm x 15mm, with a moderate thickness. The curved bezel is smooth and natural, and the polished finish shines brilliantly, maintaining AZ's usual high standards. The double-sided anti-reflective sapphire crystal features a clever cutting and polishing technique that is exceptionally challenging, with a high scrap rate. AZ spares no expense in replicating the authentic look, providing everyone with the closest possible experience to the genuine product.The movement disassembles the original IWC 52850 movement into its components. Through extensive trials and data analysis, we have achieved an 80% structural compatibility with the IWC 52850 movement, with the adjustment methods and tactile feedback being 100% synchronized.The strap buckle is made of Italian calfskin, paired with an IWC original-grade folding clasp.
