This timepiece is crafted as a multi-function mechanical wristwatch inspired by the design language of the Master Calendar series. It features a modified movement architecture designed to integrate multiple calendar complications in a compact 40mm case.
Key Features
Case and Dial Design
The watch features a slightly domed “glass-box” style dial profile with a gentle curvature visible from the side. The design has been refined through multiple adjustments to achieve a visual balance close to the reference aesthetic while maintaining its own structural interpretation.
Calendar Display Layout
At the 12 o’clock position, two apertures display the day of the week and month respectively.
The 6 o’clock sub-dial functions as a small seconds display, integrated with a moon phase indication.
The outer ring of the dial includes a date indicator, completing a full calendar presentation system with multiple synchronized functions.
Case Construction and Wearability
The case is designed with smooth continuous curvature, ensuring a seamless visual transition along the edges. The folding clasp is engineered with a tight-fitting structure to improve wrist comfort and maintain a continuous arc when closed, consistent with the overall ergonomic design concept.
Movement Specification
The watch is powered by a modified 866AA-based mechanical movement adapted for multi-function calendar operations. It is designed to provide stable timekeeping performance and support integrated calendar functionality.
Closing Statement
This model emphasizes refined aesthetics combined with functional calendar complexity. It focuses on achieving a balanced presentation of mechanical display, structural integration, and everyday wearability within a compact wristwatch form factor.
