While you probably don’t need a slide rule bezel to take care of computations such as speed and fuel consumption in a modern cockpit (if you, you know, happen to actually be flying a plane), there’s no denying that classic pilot’s watch styles still look badass. This 42mm pilots example from Casio features a rotating slide rule bezel, chronograph and a matching steel bracelet, and it’s 51% off now, on sale for just $39. While this pricing isn’t specific to Prime Day, it’s still a damn good deal.
