D e a r Custo me r,
since the company was founded in 1961, we have focused
on the creation of high-quality mechanical watches.
nowadays, watch lovers associate innovation and
patents with the name of sinn spezialuhren. and it's not
just our diving watches that stand for high performance,
robustness, and durability, quality and precision.
these watches do, however, constitute an outstanding
example of how we repeatedly push the limits of what can
be achieved physically in development.
We are driven by the question of which new technologies
and materials can be used to make diving watches safer
and more suitable for everyday use.
It is often worth indulging in a little lateral thinking to see
what is going on in other industrial sectors or fields of
science. It is therefore no coincidence that the series u1,
u2, u200, u212, u1000 and uX are made from high-strength,
seawater-resistant German submarine steel. the t1 and
t2 models are another example. all case parts for these
mission timers are made from high-strength titanium. both
submarine steel and high-strength titanium predestine our
diving watches for use in salt water.
Fittingly, we work closely with an independent company
specialising in technical maritime security. the
world's largest classification society DnV Gl (formerly
Germanischer lloyd, hamburg) checks and certifies the
diving-watch data – including compliance with european
diving device standards, which is unique in the watch
industry.
I am delighted that you have decided to buy a sInn diving
watch and hope that it will continue to give you pleasure
for many years to come.
Yours sincerely,
lothar schmidt
