This guide covers our safety folding clasp. You can recognise it by the safety flap and the two push buttons on the sides. There is one version for leather straps and one for silicone straps. They are built differently and cannot be swapped. Both open and close the same way, only the length is set differently.
Do you have a different clasp? See our guides to the folding clasp and the butterfly clasp.
How it works
Opening and closing the safety folding clasp
When you open it, only the clasp unfolds. The strap stays closed in a loop with the watch, and you slide it over your hand. This makes putting the watch on and taking it off quick.
- Lift the flapLift the safety flap.
- Press the buttonsPress both push buttons on the sides. The clasp opens.
- Take off the watchSlide the strap and the watch over your hand.
- Close the claspTo put the watch on, slide the strap over your hand and close the clasp until the buttons click into place.
- Fold down the flapFold the safety flap back over the clasp.
Leather strap
Adjusting a leather strap to your length
When you fit the strap for the first time, you set the part with the holes yourself.
- Open the claspLift the flap and press both buttons.
- Thread the strapPass the part with the holes at an angle downwards through the slot in the clasp.
- Choose the lengthPull the end until the watch fits well. The punched holes help you find the right position.
- Fix the strapPress the end of the strap onto the pin under the clasp.
Changing the length later
Pull the strap off the pin, move it and press it back on at the new position. You can do this at any time. After a long time of wear we advise against it, because the leather has already taken on the shape of the old setting.
Silicone strap
Shortening a silicone strap on both sides
The version for silicone straps has no pin. On each side, the strap is held in the clasp by a standard spring bar. It comes fitted at its maximum length. The strap has a hole for the spring bar every centimetre.
What you need: a pin or a spring bar tool thin enough for the side hole of the clasp, and scissors or a cutter.
- Find the lengthPut the watch on and check how much shorter the strap needs to be. You cut half of it on each side.
- Release the spring barUse the pin to push the spring bar inwards through the side hole of the clasp and take out the strap. You can also lever it out carefully.
- Move the spring barPut the spring bar into the hole for the new length.
- Cut off the restCut off the part behind the spring bar with scissors or a cutter. The clasp covers the cut edge.
- Refit the strapPush the strap with the spring bar back into the clasp until the spring bar clicks into the holes.
- Other sideRepeat steps 2 to 5 on the other side.
Example: to shorten the strap by 4 cm, cut 2 cm on each side. If you shorten only one side, the clasp sits at the side of your wrist. If in doubt, cut a little less first. You can always shorten more, but you cannot add length back.
Suitable straps are among our silicone straps with safety folding clasp.
Replacement
Replacing the clasp
The version for leather straps is also sold on its own, in brushed steel or gold, among our single buckles. The version for silicone straps is not sold separately.
The clasp must have the same width as your strap at the buckle end, not the lug width. Our guide shows how to measure the width at the buckle. If the strap is very thick at that point, it may not fit through the slot.
Replacement clasps come with a new spring bar. To remove the old clasp, follow our guide on replacing the buckle of a watch strap.
Already fitted, you will find this clasp on our straps with safety folding clasp. Folding and butterfly clasps are among all straps with deployment clasp.
