As I am writing about the Casio Pro Trek PRW-3500 I am asking myself, "how could Casio make this a cool smartwatch?" I think that it is possible for Casio to add useful smartwatch functionality, while at the same time, allowing a Pro Trek to maintain its reliable "go anywhere" spirit that it gets from not needing to have its time set or needing a charge.
Overall, the Ball Fireman Night Train SG50 is a really fun piece that offers lots of bang for your buck. Thanks to the atypical case design, the watch wears small and is more versatile than you might think. Furthermore, the DLC finish makes the watch more resistant to the rigors of daily wear, and when combined with the trusty ETA-2824 movement and rated water resistance of 100 meters, it just means that this watch can take about anything you throw at it. Obviously, the SG50 arrangement of micro gas tubes on the dial might not have significance to anyone outside of Singapore, but it is cool in the sense that it is the first time Ball has used micro gas tubes to form letters, and it has the most micro gas tubes of any Ball watch, which means it absolutely glows at night.
