Have you heard of the term certified Chronometer?? What is that, why do I need it, and why am I paying more for it? The fact of the matter a Certified Chronometer is the bench mark of Swiss watch making. Now, I said Swiss. There are other testing services, like Dinn in Germany which are just as good. Still, to have a Chronometer watch means timing, excellent timing rates for an automatic watch. Tested in various positions, hot, cold, etc. It keeps good time! Rolex, Breitling, Omega gobble most of the Chronometer status watches, but others make the mark too. KTTB
