This model series is designed especially for water sports and diving watch lovers. The Tissot T1208521105100 model is powered by a Swiss battery movement. Besides the time function, it is equipped with a date display at six o'clock. The watch has an EOL (End of Life) function that alerts the owner when the battery is low. The watch now comes with a GMT function, which is adapted to the 24-hour lunette and thanks to which a distinctive GMT hand has been added to the dial. The watch is made with a combination of a steel case and a steel bracelet. The dial is protected by a sapphire crystal with an anti-reflective coating, which is highly resistant to scratches. This model is characterized by a typical diver's watch design, so of course there is excellent legibility, luminescence and a unidirectional rotating diving lunette. The 300m water resistance is supported by a screw-down crown and guarantees durability in almost any contact with water, including deep diving. The original steel bracelet on this model bears the designation T613049631.
