A little over a century ago, in 1914, the Kew Observatory in Great Britain granted a Class A chronometer certificate to a wristwatch for the very first time. This replica watches
was a major achievement for the timepiece in question, a tiny Rolex watch, and it also marked the advent of the modern precision wristwatch. In this article excerpted from my omega replica
blog, Watch Insider, I explore the full story behind this watch-world milestone, and trace the evolution of the Rolex Oyster watches that resulted from it, with photos of all the major Rolex Oyster models rolex replica watches
from 1926 through 2014. Until July 15, 1914, the Class A certification, which attested to the highest chronometric precision, had generally been awarded only to large replica breitling
marine chronometers after extremely rigorous tests. Rolex was, in fact, the first to prove that a wristwatch could be just as precise as a marine chronometer - a notion that was scarcely believable at the time.
