For years, I used a Timex with digital and analog display, and date display. I need the date so I can remember whether it's an even or odd day, and so know which engine to start first. I need an analog display for calculating ETA without having to do arithmetic. I used to use the digital time for recording takeoff and landing time, but I no longer need that, because the EFB does it automagically. Sometimes. If it works. It often doesn't. If not, then I call and get the times from the comm center's computer. These days I use a Seiko Kinetic, which doesn't require a battery. It has a basic analog display and shows the date, so it's all I need. I only bought it because I found it cheap on a store closing sale, and I don't have to worry about buying new batteries and changing them. In flight, there is a clock with stopwatch functions on the dash, plus the GPS, plus the EFB which does all sorts of calculations, so I rarely need a watch in flight, much less all the other functions.
