From first glance to everyday use, the Seastar 1000 Quartz 40mm model communicates style, performance, and versatility. Each model is a harmonious marriage of elegance and technology, bringing Swiss watchmaking know how and eternal design together. This hugely versatile case size is designed to cater for people looking for a chic, tasteful watch that can cross over from day to night while still promising exceptional technical performance. As with the existing 36mm and 45.5 mm models, these piieces take their name from their water resistance certification of 1,000 feet, equivalent to 30 ATM or 300 meters. They offer uni-directional 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, giving the owner the opportunity to choose from a wide range of compatible Tissot straps and personalize their watch to suit mood or occasion.
