Manual - Butterfly Clasp
The butterfly clasp (or deployment clasp) are both stylish, reliable and safe. Our butterfly clasps are made of high-quality stainless steel and you can choose between different types of surface finishes, such as brushed or polished. Our butterfly clasps are available in gold or steel.
The clasps work on all watch straps that use a traditional fastening pin. They are easy to mount and replace. One of the absolute biggest advantages of a butterfly clasp is that it extends the life of a leather several times over compared to a classic "belt buckle".
The video below shows the function and design of the butterfly clasp. The clasp is easily opened by pressing the two "buttons" on each side of the clasp. To fasten the clasp, fold it and press on the top and the lock function is activated.
Manual - Steel Mesh Strap
With its mesh design, silver color and stainless steel, the Heritage F watch strap from SÖNER is a watch bracelet that complements SÖNER's square watches in both a modern and stylish way.
