This BLS Factory chronograph model is inspired by the design language of the Audemars Piguet Royal Oak series, focusing on structural precision, dial detailing, and enhanced mechanical-style aesthetics.
Movement
Powered by a DanDong 4401-based automatic chronograph movement with a low-profile structure of approximately 6.8mm thickness. The movement emphasizes improved stability and precision through a non-hacking balance wheel configuration, with decorative finishing applied to match the visual layout of the original architecture.
Dial Design
The dial features finely engraved branding and typography with precise proportions. The applied markers and lettering are designed to maintain consistent alignment and visual balance. The textured “waffle” grid pattern on the dial is rendered with a strong three-dimensional relief effect for enhanced depth perception.
Date Window
The date aperture is precision-engraved to create a clean, squared, and well-defined window with improved visual sharpness and alignment.
Case & Bezel
The octagonal bezel is defined by symmetrical screw placement and sharp structural geometry. The case finishing combines brushed and polished surfaces, with consistent grain direction and refined edge transitions for a cohesive industrial aesthetic.
Bracelet
The integrated bracelet is designed with gradually tapering links, improving flexibility and wrist comfort. Each link is finished with alternating brushed and polished surfaces, maintaining visual continuity and smooth articulation.
Overall Craft Style
This model emphasizes detailed case geometry, dial layering, and structural finishing inspired by the sports-luxury design language of the Audemars Piguet Royal Oak chronograph series, focusing on visual depth and mechanical-style presentation.
