Object description

Case and Dial Design

The timepiece is constructed with a 39 mm case made of stainless steel, maintaining the characteristic Royal Oak silhouette. The design includes an octagonal bezel secured by screws, which is a hallmark of this model series. The watch is complemented by an integrated steel bracelet that fastens with a folding clasp.

The dial is an 'Open Worked' skeleton style, providing a direct view of the internal mechanical components. The layout incorporates a chapter ring with minute indices and hands, which allow for time legibility while maintaining the open design. The skeletonization exposes the bridges and wheels of the movement.

Evidence for this section
  • “بدنه این ساعت با قطر 39 میلی‌متر از جنس استیل ضدزنگ ساخته شده و با طراحی نمادین رویال اوک هماهنگ است”
  • “قاب و بند این ساعت نیز از جنس استیل بوده و با یک قفل تاشو (Fold clasp) به مچ دست محکم می‌شود”

Movement and Performance

The watch is powered by the automatic caliber 3129. This mechanical movement is configured with 38 jewels and is designed to provide a power reserve of approximately 60 hours. The construction emphasizes the visual presentation of the gear train and balance wheel, consistent with the skeletonized nature of the watch.

The caliber functions as an automatic movement, meaning it winds via the movement of the wearer's wrist. The technical execution prioritizes both the aesthetic appeal of the skeletonized bridges and the functional precision of the timekeeping mechanism.
