Bokey TimeThe EW Factory Day-Date 40 Upgrade Edition introduces a refined interpretation of the classic Rolex President-style design, featuring a fully upgraded Cal.3255 integrated automatic movement and improved structural accuracy. Designed for enthusiasts who value both visual consistency and mechanical refinement, this 40mm model focuses on achieving a closer alignment with original proportions and functional behavior.
The watch features a 40mm case diameter with a thickness of approximately 12mm, maintaining balanced proportions that closely resemble the original Day-Date profile. The Oyster-style case construction includes a solid middle case, screw-down case back, and a threaded winding crown, ensuring a robust and unified structural design.
A sapphire crystal glass is used on the dial side, paired with a cyclops magnification lens at 3 o’clock for enhanced date readability. The magnification effect is designed to closely match the visual characteristics of the original configuration, offering a clear and well-proportioned date display.
At the core of the watch is the upgraded Cal.3255 integrated automatic movement. Unlike earlier versions that relied on decorative or semi-functional modules, this movement is engineered as a more complete integrated architecture. It supports smooth time adjustment, instant weekday and date jumping, and improved overall operational stability. The movement design also aligns more closely with the original functional structure in terms of user interaction and mechanical response.
The case architecture, dial layout, and functional behavior are all optimized to deliver a more coherent and consistent experience. From the smooth crown operation to the precise calendar transitions, the watch aims to replicate the intuitive feel associated with the Day-Date series.
The EW Factory Day-Date 40 Upgrade Edition is designed for collectors who appreciate the classic President aesthetic combined with upgraded mechanical integration and improved structural refinement, offering a more complete and modern interpretation of a timeless design.
