Deployant clasp vs tang buckle
A tang buckle works like a belt: you thread the strap through the buckle and close it with a pin. A deployant clasp (also called a deployment or folding clasp) stays fixed at your size and simply folds shut. That makes it quicker to put on and take off, keeps the watch from slipping off your wrist while you fasten it, and saves the rubber from being bent at the same point every day. For a full comparison, read our guide Tang Buckle vs. Deployant Clasp.
Why FKM rubber
FKM is a high-grade fluoroelastomer rubber. It feels soft on the skin, resists water, sweat and sunscreen, and keeps its shape and colour far better than basic silicone, which makes it ideal for a strap you wear every day, in the city or in the water.
How to choose your width
Measure the distance between the lugs of your watch in millimetres; that is the strap width you need. Every colour is available in 20mm. Black, White, Navy Blue, Green, Red and Orange are also available in 18mm, 19mm, 21mm and 22mm. All other colours and the LuxLine® designs are currently made in 20mm.
Choosing the clasp finish
Match the clasp to your watch case: silver for stainless steel, gold or rose gold for gold and two-tone watches, and black for black-coated cases or an all-dark look. Every clasp is made of stainless steel.
