YL Factory 1:1 Super Clone Watches – Official Factory Catalog

YL Factory (YLF) has long been celebrated by classic dress watch connoisseurs as the supreme manufacture for complicated IWC timepieces, most notably the iconic IWC Portugieser 7-Days Power Reserve (IW5007 / IW5001) and the Portugieser Annual Calendar. While other workshops produce flat printed dials or decorative faux complications, YLF engineered a customized automatic movement with a real, working mechanical power reserve gauge that measures actual mainspring unwinding.

Exhibition Caseback Artistry and Classical Dial Nuance

A major source of pride for YL Factory is the visual beauty of its movements through the sapphire exhibition caseback. The YLF movement features circular Côtes de Genève stripes, perlage on the mainplate, blued movement screws, and a skeletonized winding rotor inlaid with an authentic 18K gold-finished Probus Scafusia medallion. On the dial side, YLF’s leaf-shaped hands and applied Arabic numerals sit atop shimmering sunburst ardoise, classic silver, and deep navy blue dials.
