Skagen 596XLTXM Titanium Mens Watch

Question

I just the wrist watch listed above. I need to shorten the band, since it is too big for my wrist. How do I do it? This band is NOT the mesh type as shown in the instructions. It is an articulated metal type and has arrows imprinted on some of the links, on the inside. What does that mean? How can I make it smaller?
