FOSSIL LED watch 2002 Wristwatch Battery replaced, operation confirmed. The LED display is fully functional with no missing segments. The simple face with the FOSSIL logo has a retro-future coolness. The LED segments are dots instead of bars, making the display very vivid. Before the development of quartz watches, the LED watch developed by Hamilton was the world's first digital watch and was revolutionary at the time. However, due to high battery consumption, the time could only be seen when a button was pressed, which was inconvenient. Amidst this, various companies entered the LED watch market, and it evolved with creative innovations such as touch-sensitive and shake-to-display types. Although LED watches were flourishing, they were eventually replaced by the release of inexpensive, low-power LCD digital quartz watches. In the history of wristwatches, it can be said that it was an unfortunate watch, a revolutionary idea that had a short period of activity. LED watches are prone to circuit board failure, but this model, despite being over 20 years old, is fully functional. It is very valuable. Minor signs of use, scratches, and small imperfections. The wrist size can be adjusted with the clasp.
