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 watches
(technischer Standard Fliegeruhren – 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.
