Why choose rubber over the steel bracelet

Silicone rubber is lighter than a steel bracelet and soft and flexible on the wrist, so it is a quick, comfortable swap for daily wear. The folding buckle keeps the strap set at your length, much like the clasp on a bracelet.

How to fit it

1. Lay the watch face down on a soft cloth so the case and crystal are protected.
2. Use a spring bar tool to compress the spring bar at each lug and remove the current strap.
3. Seat a spring bar in each end of the new strap, place one tip in the lug hole, compress the other tip and let it click into place.
4. Pull gently on both sides to check it is locked in. Never open the case back: the strap attaches only at the lugs.

Frequently asked questions

How do I know if my Longines takes 21mm?

Measure the gap between the inside edges of the lugs on your watch. If it is 21mm, this strap is the right width.

Can I swap back to my bracelet later?

Yes. The strap attaches with spring bars at the lugs, so you can refit your bracelet the same way.

What colours are available?

Black, blue, gray or green, each with a silver folding buckle.
