One of the unique selling points of the Ref. 116519LN is the Oysterflex strap, which is only used in a few Rolex references. What at first glance looks like a simple rubber strap is high-tech through and through: At the core of the reference's Oysterflex strap is a highly elastic metal spring leaf which, like the rubber lips on the underside, contributes to the high wearing comfort.
Since a total of six strap lengths are available for both bracelets, the right length can be found for every wrist. It also features the convenient Easylink extension, which allows the Rolex Ref. 116519LN wrist strap to be extended by approximately five millimetres in no time at all.
