Roger Dubuis Excalibur Quatuor Cobalt MicroMelt Watch With Complicated Dial

Quatuor is so-called because it was the first watch in the world to have four balances - all in the name negating the harmful effects that gravity has on timekeeping. In addition, in another world-first, there was also a limited edition of the Quatuor that has a case made out of silicon. It is, therefore, fitting that Roger Dubuis has done it again by being the first watch to use cobalt chrome.

According to Roger Dubuis, the cobalt chrome case of the Roger Dubuis Excalibur Quatuor Cobalt MicroMelt watch is produced using an exclusive process called MicroMelt. This involves a long list of processes that include melting and atomizing the alloy into a fine powder before being blended and poured into canisters where they are sealed and pressed to produce highly dense hot-rolled bars. The MicroMelt process ensures that the resultant product is uniform in its density, which translates to higher strength. High strength aside, the use of this unique alloy also means that the Roger Dubuis Excalibur Quatuor Cobalt MicroMelt watch has a sheen that is unlike any stainless steel or titanium case watch.
