Innovations and certifications
the world’s largest classification society for maritime safety DnV Gl (formerly
Germanischer lloyd, hamburg), has been testing our diving watches
for pressure and water resistance since 2005. as part of DnV Gl’s official
certification process, our diving watches have been treated as part of diving
equipment since 2006 and tested and certified in accordance with european
diving equipment standards. this is unparalleled in the watch industry.
We have had selected pilot’s watches tested and certified to the technical
standard for pilot’s watches (testaF) by aachen university of applied
sciences since 2012. the testaF, the result of a research project at the initiative
of sinn spezialuhren, ensures that a pilot’s watch meets all timekeeping
requirements during flight operations in accordance with visual and/or
instrumental flight regulations and is suitable for professional use.
DIapal is one of our most important technological developments, with oiling
no longer needed for the most important functions in the watch thanks to
the materials we select. this technology was first used in 2001. With the aid
of teGIment technology, we achieve greatly increased scratch resistance
through surface hardening.
