POPSTRAP Size Guide
POPSTRAP Size Guide
POPSTRAP is one-size-fits-most. Here is how to make sure it will fit your wrist and how to adjust it. POPSTRAP is sized for the 40mm Royal Pop AP × Swatch case; measure your wrist circumference between 145mm and 200mm for the correct Royal Pop fit.
Quick answer
POPSTRAP fits wrists from 145mm to 210mm in circumference. The strap has 8 adjustment notches on the tang buckle, covering small to large wrists with no need for resizing.
How to measure your wrist
- Take a strip of paper or a flexible measuring tape.
- Wrap it around your wrist where you usually wear a watch (just above the wrist bone).
- Mark where the paper meets and measure in millimeters.
- That is your wrist circumference.
Sizing table
| Wrist circumference | POPSTRAP fits? | Notch used (out of 8) |
|---|---|---|
| 145–155mm (extra small) | Yes | 1–2 |
| 155–170mm (small) | Yes | 2–3 |
| 170–185mm (medium) | Yes | 3–5 |
| 185–200mm (large) | Yes | 5–7 |
| 200–210mm (extra large) | Yes (tight) | 7–8 |
| 210mm+ | May not fit comfortably | — |
How to adjust POPSTRAP
POPSTRAP uses a traditional tang buckle (no spring bars). To adjust:
- Put the watch on your wrist.
- Pass the long end of the strap through the buckle.
- Slide the pin into the notch that gives you a comfortable fit — you should be able to slip one finger between the strap and your wrist.
- Secure the loose end through the keeper loops.
Should I size up or down?
Silicone has slight memory and stretches by about 2mm over the first month of wear. If you are between notches, choose the tighter one — the strap will relax into the perfect fit.
Can I trim POPSTRAP?
We do not recommend trimming the strap. The keeper loops are positioned for the full length, and trimming voids the warranty. If POPSTRAP is too long after maximum adjustment, contact us for a fitting consultation.
My wrist is below 145mm — will POPSTRAP fit?
Below 145mm, the strap will fit but the leftover tail may stick out past the keeper loops. Email us with your measurement and we will tell you whether it works for your specific case.
