PPF Edition — Black Rubber Strap
PPF’s Nautilus 5726 represents a significant technical milestone in replica horology, specifically addressing the complex case construction of the annual calendar reference. Unlike earlier iterations that relied on a compromised three-part case, PPF utilizes a 1:1 structural approach, integrating the bezel and mid-case accurately to mirror the genuine 40.5mm profile.
Powering this complication is the PPF modified Clone 324 caliber. The architecture incorporates a custom module to drive the day, date, month, 24-hour, and moonphase indicators with precise corrector pusher alignment. Due to the modular nature of these complications on the base movement, the power reserve yields approximately 36 hours.
The gradient grey textured dial is executed with accurate horizontal embossing, capturing the subtle metallic sunburst effect characteristic of the genuine article. Encased in 904L stainless steel, the alternating brushed and polished finishes extend to the deployant clasp, securing the integrated black rubber strap with strict lug tolerances.
