I’ve emphasized multiple times that Z factory excels in crafting top-quality replica IWC watches, particularly the revered IWC Portuguese 7 Days Power Reserve, hailed as a classic timepiece in our market. With a notable 3-day power reserve, a significant breakthrough in itself, ZF has further surprised enthusiasts in early 2019 by introducing the latest models of the Portuguese Annual Calendar. This release solidifies Z factory’s dominance in the replica IWC Portuguese domain, and the subsequent review will provide insights into these watches along with accompanying photos.
The IW503502 series comprises four watches, three of which feature a white stainless steel finish, while the remaining one boasts a rose gold case. For illustration purposes, I’ll focus on the stainless steel model with a black leather strap. The case, constructed from solid 316L stainless steel, measures 44mm in diameter with a thickness of 14mm. The round case and thin bezel contribute to an expansive dial appearance, adhering to the classic design seen in many dress watches. Reflecting the simplicity and elegance characteristic of IWC Portuguese, the case features polished front face lugs, brushed sides, and improved lug curvature for a closer resemblance to the genuine counterpart. The case back is transparent, revealing the intricate details through sapphire crystal.
The white dial presents all the watch functions prominently. Positioned at 12 o’clock, an annual calendar window displays month, date, and week. At 3 o’clock, a small dial serves as a 7-day power reserve indicator, showcasing the remaining energy. Although the replica lacks a genuine 7-day power reserve, it accommodates two days of timing with a single full winding.
Powering the IWC Portuguese Annual Calendar replica is an Asia IWC 52850 automatic movement. ZF meticulously disassembled all 326 components of the original movement, achieving a remarkable 90% similarity in appearance. Furthermore, the clone movement replicates the adjusting method and winding feel precisely, matching the original. Given the watch’s transparent case back, ZF focused on intricate movement decoration for an authentic aesthetic. The accompanying photos showcase the four Portuguese Annual Calendar watches.
