The Lan Ba is the steadiest blue in the Royal Pop line, and our Case-Strap finally lets you wear it. This rubber kit takes the Audemars Piguet × Swatch Royal Pop out of your pocket and onto your wrist, with a moulded octagonal case and integrated strap in the blue with light-blue accents of the Lan Ba itself. The watch head pops out of its original carrier and seats into the case in seconds, with no tools and no harm to the watch. It returns to pocket-watch form just as easily whenever you want it back.

Rubber gives the kit a light and flexible everyday feel. If you prefer a denser, more finished one, the ceramic version of the Royal Pop Case-Strap is also available. Both share the same precise fit to the Royal Pop's head, in the Savonnette format with the crown at 3. Together, the case and the watch read as a single piece in the Lan Ba colorway.
