[Selectron] The Power Dive – A rare "Pepsi" complication that actually stays in the rotation
I wanted to share a piece that has been a mainstay in my collection for a few years now: the Selectron Power Dive. The Selectron name originally gained fame in the 1960s through its close ties to Ollech & Wajs and their iconic "computer" slide-rule watches. While the brand has evolved over the decades, this modern iteration leans heavily into that heritage of tool-first engineering, trading the vintage slide rules for a more robust diving aesthetic.
Under the hood, it’s powered by the Seiko NE57A automatic movement, which brings a 21,600 bph beat rate and a very cool central power reserve complication along with a pointer date at the six o'clock position. The 200m water resistance and the classic "Pepsi" bezel make it a officially a Diver, while the textured waffle dial adds some great depth that really catches the light.
I’ll be honest—I’m usually not a fan of power reserve indicators, as they often feel like an afterthought that clutters the dial. However, on this model, the central hand layout gives it a technical, instrument-like feel that just works. What really keeps this in my rotation is the physical presence; it has a fantastic heft and the bracelet is surprisingly comfortable. It’s been running strong at about +11 s/d since I acquired it a few years back, and despite having a large collection to choose from, this remains one of my most frequent go-to pieces.
