From first glance to everyday use, the Tissot Seastar 1000 Quartz 40mm model communicates style, performance, and versatility. Each model is a harmonious marriage of elegance and technology, uniting Swiss watchmaking know-how with timeless design. This versatile case size is for people who want a chic, tasteful watch that transitions from day to night and delivers exceptional technical performance. As with the existing 36mm and 45.5 mm models, these pieces take their name from their water resistance certification of 1,000 feet, equivalent to 30 ATM or 300 meters. They offer unidirectional rotating bezels for reliably timing underwater activity. Low-light legibility is further enhanced by the application of Super-LumiNova® to the watches’ hands and hour markers. Straps and bracelets can be interchanged using Tissot’s easy-to-use quick-strap-change system, allowing the owner to choose from a wide range of compatible Tissot straps and personalize their watch to suit their mood or occasion.
