To find which strap length is right for you, you’ll need your wrist measurement. Use a tape measure, or a simple strip of paper or string as shown below.
Step 1 – Wrap the strip/string around your wrist at the point where you wear your watch.

Step 2 – Measure the strip/string against a ruler.

Still unsure which length is right for you? Contact us and we’ll be happy to help.
Wear your AP × Swatch Royal Pop Ocho Negro on the wrist.
Kind to your watch. Your Royal Pop sits inside the Monocoque like a finger in a well-fitted ring. Nothing is forced against the metal. A small K-Clip made from PETG, a tough, slightly flexible engineering polymer, holds the watch securely. The inside of the case is wet bead blasted to a super smooth finish. Nothing is modified. Take it out whenever you like.
Made in Britain. Each Monocoque is milled from a single block of 7075 aluminium on a 5-axis CNC, in the same Bicester, Oxfordshire facility that machines gearbox and engine parts for Formula 1. The aluminium is AMS 4124 specification, sourced through the same UK aerospace supply chain that serves major aircraft makers. Material certification is available on request.
Make it yours. Choose your case colour and strap colour above. Black carries the watch's black and white discipline across the wrist. Silver frames the white bezel as the focal point. Four case colours and twelve strap colours to choose from.
About the Ocho Negro. The most monochromatic of the Lépine six. A black tapisserie dial, white bezel, black crown and eight black hex screws.
