Royal Pop Wrist Strap Size Guide

Find the perfect fit for your Royal Pop wristwatch conversion. All our straps are designed for comfort on a range of wrist sizes.

How to Measure Your Wrist

  1. Wrap a flexible tape measure around your wrist just above the wrist bone
  2. Note the circumference in inches or centimeters
  3. If you don't have a tape measure, use a strip of paper — wrap it, mark where it overlaps, and measure the length with a ruler

On-Wrist Dimensions

With the RP Wrist Adapter installed, the total on-wrist dimensions are:

  • Case diameter: 42mm (adapter adds 1mm per side)
  • Lug-to-lug: 48mm
  • Total thickness: 14.5mm (watch head + adapter)
  • Weight: ~65g with silicone strap, ~140g with steel bracelet

Recommended Wrist Sizes

  • Small wrists (5.5"–6.5"): Sport Silicone is the most comfortable. The 42mm case wears well on smaller wrists due to the short 48mm lug-to-lug.
  • Medium wrists (6.5"–7.5"): All straps fit perfectly. Leather and FKM offer the best proportions.
  • Large wrists (7.5"–8.5"): Steel bracelet or silicone recommended. Leather may be snug — contact us for long-strap options.
