The Classic Sonata offers a few different complications. We’ll start with the simple and then work our way up. First is the simple large date display at 4 o’clock. Nothing crazy there. Then there’s the 24-hour dual time display at 6 o’clock, which usual a central hand to show a second hour (in addition to the time shown by the three central hands, of course). But then we have the namesake complication for this watch, the cathedral gong alarm. You set the alarm on the large dial at one o’clock, which houses the alarm’s power reserve indicator inside of it. Then at 10 o’clock is the on/off display so you don’t end up hearing those chimes when you don’t want to (or, worse, miss that important morning meeting because you didn’t turn the alarm on).
