Forums are a goldmine today. A lot of people assume that automatics move as smoothly as butter. This is not the case. Sweep second hands “tick” but they tick up to 8 times per second, making them look like they are moving without stopping. Remember – these are still gears and gears have teeth. Even the most beautiful Rolex still “ticks” a little. If it’s ticking once per second, then you’ve got a quartz or a big problem.
