How to attach a strap to the watch?
All straps are interchangeable and have quick release pins. The quick release pins allow for easy attachment and detachment of the straps. Before changing the straps place your watch face down on a clean surface. Next, look for the pins on the back of the strap. Pull the pin a bit and move the springbar in between the lugs on the watch case. The shorter strap with buckle should always be secured above the logo and the longer strap below the logo.
