Sector “No Limits” is an Italian watch brand founded in 1973, renowned for its sports and diving watches and for its iconic “No Limits” slogan. This philosophy has shaped the brand’s identity, embodying durability, exploration and performance in the most demanding environments. Sector gained international recognition through its sponsorship of major expeditions and elite athletes from the worlds of sailing, diving and extreme sports. Its ambassadors have included renowned adventurers and sportsmen such as Gérard d’Aboville, Umberto Pelizzari, Bruno Peyron, Mike Horn, Mika Häkkinen and Alberto Tomba. The Sector No Limits 500 belongs to the generation of professional sports watches produced during the 1990s and early 2000s, a period in which Sector expanded its range of robust chronographs designed for divers, parachutists and adventurers. Despite its Italian heritage, Sector timepieces from this era proudly bear the Swiss Made designation, reflecting their manufacture in Switzerland.
