Description

The Fluxa Magnetic Silicone Sport Strap brings flexible comfort, clean ribbed styling and easy magnetic adjustment to watches with standard 18mm quick-release lugs.

Embedded magnets run through the segmented silicone construction to create a smooth, continuously adjustable hold. The strap end passes through a fixed retaining loop before folding back against the wrist, helping keep the overlap aligned and secure without a conventional buckle or adjustment holes. Its soft, wipe-clean surface is suited to everyday routines and active wear.

  • Flexible silicone construction with a ribbed, segmented finish
  • Embedded magnetic closure for continuous adjustment
  • Fixed retaining loop keeps the overlapping end aligned
  • Buckle-free and hole-free fit
  • Standard 18mm quick-release spring bars
  • Tool-free installation and removal
  • Wipe-clean surface for everyday wear
  • Available in Black, Beige, Plum, Navy and Maroon

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.

Before wear, confirm both spring-bar ends are fully seated and the magnetic overlap has full contact through the retaining loop.

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.

Will the magnetic link system stay secure?

Yes — the strap uses a reinforced neodymium magnetic link system designed for reliable, everyday wear. The segmented links hold their position firmly while still micro-adjusting smoothly to the shape of your wrist for a comfortable, precise fit throughout the day.

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.

Can I wear it for workouts, showers, and daily movement?

Yes—this strap is comfortable and sweat-resistant, making it great for everyday use, walks, casual workouts, and general activity. The magnetic link design keeps the fit secure and easy to adjust throughout the day.

For high-intensity training or exercises that put pressure on the wrist (like weightlifting, CrossFit, boxing, or rowing), we recommend switching to a sport-style strap for maximum stability and comfort.

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.
