Longines Ultra-Chron Chronometer 8353-2

The Longines Ultra-Chron is a collection produced in the late 1960s and early 1970s that stands out for its high precision. The name "Ultra-Chron" refers to the high-frequency movements of these watches. These movements have a higher vibration rate than traditional movements (36,000 beats per hour or 5 Hz), which allows for more precise timekeeping. They were created to compete with the rise of quartz watches at the time and represent the pinnacle of mechanical watch technology. The Longines 8353-2 is an important vintage model that demonstrates Longines' mastery of high-precision watchmaking. As part of the "Ultra-Chron" collection, it combines technological innovation and elegant design. If you are interested in vintage watches and are looking for a high-frequency mechanical watch, you can consider this model. The product you are reviewing was produced in 1967.
