Why Choose This
-
Reduces Strap Wear — The folding mechanism stops you from bending and pulling the leather, which prevents cracking and stretching over time.
-
Secure Double-Lock — The dual-button release system ensures the clasp only opens when you want it to, keeping your watch safe.
-
Comfortable Fit — The smooth inner surface sits flat against your skin and eliminates the bulk of a traditional buckle tongue.
-
Quick Release — Once you set the initial length, you can snap the watch on and off your wrist in seconds.
-
Refined Aesthetics — This clasp hides the strap tail underneath, creating a clean and continuous look around your entire wrist.
Materials & Build
Each Butterfly Deployment Folding Clasp Buckle is machined from solid 316L stainless steel. This specific grade of steel is chosen for its resistance to corrosion and sweat, ensuring the mechanism does not stick or rust after daily use. The black and gold versions use a vacuum PVD coating process that bonds the color to the metal at a molecular level, so it resists scratches and maintains its finish even with frequent contact against desks or laptop surfaces.

Sizing & Fit
To ensure a perfect fit, please measure the width of your strap at the point where it connects to the buckle. Note that many watch bands taper, so a strap that fits 20mm lugs might actually require an 18mm buckle. This clasp is designed to accommodate strap thicknesses up to 3.5mm. It is not suitable for single-piece NATO straps because the mechanism requires two separate strap ends to function properly.

FAQ
How do I know which size to order?
You must measure the width of your strap at the buckle end, not the watch lugs. Use a caliper or a ruler with millimeter markings to check the current buckle width. If your strap is 20mm at the watch but narrows down at the end, you will likely need an 18mm clasp.
Is this buckle difficult to install?
Installation is straightforward and takes about two minutes. You simply use a spring bar tool to remove your old buckle and then use the included spring bar to click the new deployment clasp into place. It works exactly like changing a watch strap on your watch case.
Will this work with a NATO strap?
No, this Butterfly Deployment Folding Clasp Buckle is only compatible with two-piece straps. Because NATO and Zulu straps consist of a single long piece of material that passes behind the watch, they do not have the necessary open ends required for a deployment mechanism to attach securely.
Does it come with the spring bars needed for setup?
Yes, we include the necessary spring bar with every buckle. You will have everything you need to complete the swap immediately. We recommend using a dedicated spring bar tool to avoid scratching the finish of the steel or your strap during the installation process.
What is the benefit of a butterfly clasp over a standard one?
A butterfly clasp opens wider than a standard folding clasp, making it much easier to slide over your hand. It also distributes the pressure more evenly across the underside of your wrist, which many users find significantly more comfortable for all-day wear compared to a sharp pin buckle.
