What’s In Your Watch? The OMEGA 8500 / 8900 / 8520 Calibers and Ron Gordon’s Certification

For most New Yorkers, the phrase, “What’s in your wallet,” brings to mind the ubiquitous CapitalOne commercials. “As seen on TV,” as they say. A range of famous stars such as Jennifer Graner or Samuel Jackson explain the in’s and out’s of good financial sense (and the “advantages” of a CapitalOne credit card), ending with the famous slogan, “What’s in your wallet?” We can’t specify whether CapitalOne is a good or bad credit card, but we do see a lot of famous Hollywood stars in and around New York City.

What’s more, we know what’s “in” various OMEGA watches. These “calibres” (also spelled, “calibers”) or “movements” are essentially the insides of the watch – the “movement” that powers the watch. The Ying to the Yang, the engine inside of the car, the thing that makes it go. According to Hodinkee, “The word “calibre” has a number of different meanings, but in watchmaking the word is synonymous with “movement.” Across the entire industry, one of the few absolutely ubiquitous practices is to call a movement “calibre XYZ123.” Among the most important OMEGA Calibres we find –

Each OMEGA Calbre has its advantages and disadvantages, and each is perfectly matched to the watch case or exterior. Think of it as the engine inside a Porsche vs. the exterior of the automobile. The essence of great designs it the blending of interior and exterior to create a perfect match of beauty and workability, of form and function.
