One of the questions that frequently gets asked is what what are the exact dimensions of a given watch. When I write an article on a watch I typically include physical dimensions of the watches that are the topic of the article. Since most of my articles have been written about Omega Chronographs, I thought a single page with all of the dimensions listed in one place for the convenience of the reader for comparision purposes might prove useful... Please realize the information contained within is limited by watches I have had physical access to long enough to measure and weigh and that there remain gaps in which watches are covered.. If you have additional information to share please feel free to contact the author...

NOTE: Unless otherwise indicated, all measurments in mm., all weights in Grams...
