IWC Mark XX IWC328203 40mm GSF Blue Dial Blue Leather

When GS Factory (GSF) disassembled a genuine reference to tool the molds for the IWC Mark XX IWC328203 40mm GSF Blue Dial Blue Leather, they started with the movement bridges and worked outward. That’s why the 40MM (1:1 Factory Dimensions) case in Solid 316L Stainless Steel (Satin & Mirror Finished) sits flat on the wrist and houses the 1:1 Cloned Swiss Automatic Calibre (28,800 vph) (48–70 Hour Power Reserve) without adding a single millimeter of excess thickness.

Metallurgy, Crystal Clarity & Wrist Balance

Dial legibility is anchored by diamond-cut hands, evenly filled luminescent plots, and a flush sapphire crystal. The bracelet links articulate on solid threaded pins rather than friction sleeves, making sizing straightforward with a standard 1.4mm screwdriver.
