Detailed Features & Upgrades
-
New 126xxx Generation Aesthetics:Ref. 126509 features the updated proportions of the latest Daytona generation, characterized by refined case lines and optimized lugs. VSF utilizes premium 904L stainless steel for the entire construction, applying an advanced vacuum plating process to accurately replicate the distinct, heavy luster and warm hue of authentic 18K white gold.
-
Custom DD4131 Movement:Beating inside is VSF’s exclusive DD4131 super clone, specifically developed for the new generation Daytona. This movement perfectly mirrors the genuine 4131 architecture, featuring the updated aesthetic finishes on the bridges. The critical achievement is the inclusion of the free-sprung balance wheel, which matches the genuine visual structure and provides vastly superior rate stability compared to standard clones. It ensures a smooth vertical clutch engagement and true column-wheel chronograph functionality.
-
Striking Black Racing Dial:The dial is flawlessly executed, featuring a deep gloss black surface that provides maximum contrast. The new generation features slightly slimmer applied 18K white gold plated hour markers and narrower, highly textured silver rings on the three snailed sub-dials. The striking red “Daytona” text adds a sporty touch, while premium Chromalight ensures a powerful, long-lasting blue glow in low light.
-
Precision Engraved Bezel:The fixed, high-polish white gold-plated tachymetric bezel is a defining element of this model. VSF has executed the deep CNC engravings with absolute precision, filling them with fade-resistant black enamel to accurately calculate speeds of up to 400 units per hour.
