Crafted by Strapify, our patent-pending high-performance Vanguard folding clasp is made from 316L Stainless Steel, ensuring it is both light and highly durable. This premium material feels smooth and comfortable against your skin. With a unique adjustable system, you can fine-tune the strap length up to 6mm in 6 precise increments, all without removing your watch. This patent-pending design offers superior comfort and a tailored fit for any situation. We've developed this clasp from the ground up and we know how frustrating it is to buy a clasp and only to find it doesn't fit a thicker strap. We've added extra clearance between where the spring bar sits and the edge of the clasp without compromising on aesthetics or durability.  This clasp folds the tail end of the strap UNDER itself. This means the tail is neatly tucked away underneath to prevent any tail overhang. This is great for those with small wrists. Because the tail sits under the clasp, this makes it significantly more comfortable than any other deployant clasp on the market as your skin has minimal contact with the metal clasp. Good to know: Great for small wrists because these will use up wrist space as they sit under the strap These will also fit thicker straps as we have added clearance between the spring bar holes to ensure these fit a majority of straps! This will fit any strap that uses a traditional buckle. Features: Press the inner button to access up to 6mm of instant micro-adjustment Made from 316L Stainless Steel and springs made from 304 Stainless Steel Squeeze button mechanism to release with an internal button for on the fly micro-adjustment Neatly tucks the tail end of the strap UNDER the strap to fold away neatly (see second picture). Maximum comfort as the tail of the strap sits UNDER the clasp to minimise contact with the metal clasp. Rachet system which will also tighten if the strap is pushed towards the clasp (without pressing the button), but will not loosen.
