Every Chronoswiss watch is an expression of Gerd-Rüdiger Lang´s personal philosophy. That's why the founder and owner personally signs each guarantee certificate. And to ensure that your time is unmistakably yours, before shipping it off, each watch is stamped with our hallmark. We also engrave the individual case number and reference number onto the case, thus making this particular Chronoswiss watch into your personal Chronoswiss. We guarantee each watch for a period of two years, beginning with the date of purchase, against any manufacturing or material errors, and you have the word of Gerd-Rüdiger Lang that each timepiece will run at a reliable rate.

Nonetheless, despite countless tests and certifications, mechanical watch movements aren't entirely immune to errors. That's simply part of their fascination. You should always be aware upon buying a Chronoswiss, this certificate is only valid with the signature and the stamp of our official authorized dealer.
