The new Seiko Prospex Speedtimer Mechanical SPB513 is not a chronograph, but when we think of a modern Seiko Prospex Speedtimer, we think of a chronograph, because all the modern Speedtimer watches in the Seiko catalogue are chronographs. Right? So what does it do then?

Though not a chronograph, it is still a racing-inspired wristwatch, with functionality not limited to just the world of racing. Though, to be fair, chronographs are also not limited to just motorsports. In place of a chronograph, the SPB513 marries a time and date watch with a countdown bezel, which, as Seiko describes it, could be used to track the time remaining before the start of a race or target durations, such as a pit stop. Zach, however, can envision a world in which he would ensure his boiling pasta comes out perfectly al dente. What would you use the countdown bezel for? Let us know in the comments.
