This (even more improved) divers’ clasp is extremely robust and makes it possible to lengthen your bracelet without taking off your watch. Just press on the sides and you can add almost 2 centimeters to the bracelet (18mm, 8 positions). At the back end there is even an extra adjustment hole, so you can make your bracelet your wrist with ease. It is made of stainless steel, brushed finish with nicely polished facetted edges.
The length (closed) is 3.75cm and the heigth/thickness is 7.1mm.
Improvements: even shorter and less high adding a millimeter more extension length.
