Description

The Jelli Silicone Sport Strap gives watches with standard 18mm quick-release lugs a playful jelly-band look with translucent two-tone colour blocking and a ventilated sport profile.

Flexible silicone and elongated ventilation openings encourage airflow and reduce broad wrist contact during activity. A conventional silver-tone tang buckle provides familiar, precise adjustment, while the matching keeper loop controls the strap tail. Integrated quick-release spring bars make installation and removal simple without tools.

  • Playful jelly-style, two-tone colour design
  • Flexible silicone construction
  • Ventilated openings for improved airflow
  • Silver-tone tang buckle with keeper loop
  • Multiple adjustment positions for a secure fit
  • Standard 18mm quick-release spring bars
  • Tool-free installation and removal
  • Sweat-friendly surface that wipes clean easily
  • Available in Black, Green, Yellow and Purple

Compatible only with watches that use standard 18mm quick-release lugs. Measure the internal distance between your watch lugs before ordering; case diameter does not determine strap width.

For a secure fit, seat both spring-bar ends fully in the lug holes and fasten the buckle through the selected adjustment opening before wear.

Tried, Tested, Trusted

Swapped in, worn out—here’s the verdict.

Will this strap be compatible with my watch?

Yes — this strap uses a quick-release spring bar and is designed for watches that use 18mm straps. It attaches with a simple push-click connection and requires no tools.

If you’re unsure whether your watch uses 18mm, just send us your watch model name — we’ll confirm it for you in a few seconds.

Is the strap comfortable for all-day wear?

Yes — the strap uses soft-touch, flexible silicone that sits comfortably on the skin without sticking or dragging. It’s lightweight and shaped to follow the natural curve of your wrist, so it stays comfortable from morning to night.

Will it irritate my skin or cause sweat build-up?

No — the silicone is skin-safe and hypoallergenic, made for long wear. It doesn’t trap heat like cheap rubber straps, so your skin can breathe and stay comfortable even in warm conditions.

Can I wear it for workouts, showers, or daily activities?

Yes — the strap is sweat-resistant and water-ready. You can wear it to the gym, in the shower, or through your day-to-day routine. Just rinse and dry occasionally to keep it looking fresh.

How long does shipping take, and will I receive tracking?

We ship your order within 24 hours, and every package includes door-to-door tracking.

Delivery time is usually 5–12 business days, depending on your location and local carrier speed. Most customers receive their order sooner. You’ll automatically receive a tracking link by email as soon as your order ships.

What if I don’t like it or it doesn’t fit right?

You have 30 days to try it at home.

If the fit, color, or style isn’t right, we’ll help you exchange it quickly — no hassle. And if you’d still prefer a return, no problem — just send it back in its original condition and we’ll refund you.
