In this guide to modern sports watches, discover honest assessments of luxury sports models, many varieties of chronographs, GMTs, and extreme diving watches, represented by the best sports brands in the world, including Patek Philippe, Breitling, Omega, Chronoswiss, and more. But first, what exactly is a sports watch? Jewellers, connoisseurs, and the editors have agreed on the following definition: a sporty-looking timepiece, usually made of steel, that stays on your arm whether you're racing, diving, or flying. In the 1970s, Gerald Genta designed three classic sports watches that challenged conservative styles and remained virtually unmodified for more than thirty years. Using Genta's legacy as a starting point, this new book traces the evolution of the sports watch to today, focusing on the 21st century, from simple, robust steel watches with three hands to more complicated timepieces, with detailed technical comparisons between models, some of which are already considered classics.
