Royal Oak Openworked: A Look at the Gem Set Design
Share
An openworked Royal Oak reveals the movement through the front of the watch. In this gallery, dark bridges and warm colored details sit within a bright, heavily gem set case and bracelet. The contrast makes the movement the visual center of the watch.
Openworked Does Not Identify the Movement
Royal Oak references have different sizes, movements and functions. For example, Audemars Piguet documents reference 15407ST.OO.1220ST.01 as a 41 mm Double Balance Wheel Openworked watch with calibre 3132. Specifications from a Jumbo, a smaller automatic model or a chronograph should not be substituted for it.
The photographs alone do not verify the full reference of this featured watch. Its documentation should establish the movement and case specification before those details are used in a purchase decision.


The Details in These Photographs
The angular bezel retains the Royal Oak outline, with visible screw positions around the opening. Rectangular stones follow the bezel, while smaller stones cover broad areas of the case and bracelet. Inside, the open spaces between the bridges reveal depth that a conventional dial would conceal.


Check the Setting History
A gem set appearance does not establish that Audemars Piguet supplied the setting. Ask for documentation identifying any aftermarket work, the stones used and the parts altered. Setting quality, bracelet movement, service eligibility and the condition of the underlying watch all deserve inspection.
For an everyday fit, try the bracelet on and check how the case sits on your wrist. Contact our Boca Raton showroom for help comparing a documented Royal Oak with the look shown here.
