Designed and engineered by Formex, this high-tech folding clasp is made of injected micro fiber carbon composite, an ultra-light but durable material that feels smooth on the skin. You can fine-adjust the length of the strap by 7mm, gradually on 6 micro-steps, without having to take off your watch. This patented feature notably provides more comfort and allows the perfect fit in all conditions.
The folding clasp fits straps with a width of 20mm on the buckle and is designed for Formex REEF and ESSENCE 43mm leather, rubber & nylon straps marked "deployant". It can be interchanged without the use of any tools and in a matter of a few seconds.
