Find Your Royal Pop Case Size First
Before buying any strap, confirm your exact Royal Pop case size. The collection spans 38mm, 41mm, and 42mm cases, and each uses a specific lug width, so a strap built for one size will not fit another correctly. Your case size is usually printed on the original paperwork or engraved on the case back. When in doubt, measure the lug width in millimeters with a ruler or caliper, and always match that number to the strap listing.
38mm: the most compact case, best for smaller wrists
41mm: the most popular, balanced everyday size
42mm: the largest, boldest wrist presence

How to Measure for a Perfect Fit
Measuring is simple. Lay your strap flat and measure the lug width in millimeters where the strap meets the case. This number tells you which size to order. For wrist comfort, wrap a soft tape measure or a strip of paper around your wrist and note the length in millimeters, then check it against the strap's sizing chart. A well-fitted strap sits snug without pinching and leaves about a finger of room.
