Formex Field "Deployant" Clasp with Fine Adjustment

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 18mm on the buckle and is designed for Formex Field leather straps marked "deployant". It can be inter-changed without the use of any tools and in a matter of a few seconds.
