P-104 S from Ollech & Wajs: Swiss-made Watch with Retro-inspired Slide Rule Functionality

Swiss-made, robust, functional, retro-inspired, durable

Ah, let me tell you about a little gem that’s garnered my attention. Nestled in the heart of the Swiss Jura, a creation is being patiently crafted – the P-104 S by Ollech & Wajs. As intricate and masterful as any Swiss timepiece should be, it's a watch with purpose, built for those who aren't afraid to ascend the heights or dive the depths.

Our journey begins with the design. Taking inspiration from the control panels in cockpits, the dial screams practicality yet whispers elegance. And when night falls, fear not! The checkered hands and oversized indexes, slathered generously in Super-LumiNova®, ensure maximum readability in the dimmest of light. It’s like having an ever-glowing torch strapped to your wrist, never leaving you in the dark.

The P-104 S prides itself on functionality. Underneath the hood, it is powered by the robust mechanical movement of ETA 2824-2 OW3, adjusted meticulously for precision. Its circular slide rule, once you get the hang of it, is a charming throwback that allows you to calculate a range of data on the fly, no pun intended.

But the attention to detail doesn't stop at the dial. The casing – brushed 316L stainless steel, manufactured right there in Jura, Switzerland – is built to withstand the pressures of a 300-meter dive. Even the glass, a sapphire treated with anti-glare, demonstrates a commitment to clarity and durability.

Let’s now wander down the bracelet, where the workmanship really shines. The links are not just brushed and assembled, but also screwed by hand, a time-consuming process that banishes the usual stretching of common steel bracelets. Each bracelet is reminiscent of the classic 1960s models from Ollech & Wajs, made from a solid block of stainless steel that promises longevity and comfort.

To the adventurists out there, this watch is your trusty sidekick, the companion you need when charting unknown territories. Whether you're scaling mountains, navigating the skies, or plunging into the azure depths, it's designed to weather the elements alongside you.

And just to touch on the wait time – twelve weeks from ordering date – it might seem a bit lengthy. But remember, the most sumptuous of meals need time to simmer. Patience, my friends, for when it arrives, you will have in your hands, a symbol of dedication and craftsmanship that’s well worth the wait.

The P-104 S is more than just a timepiece; it's a tribute to adventure, to the beauty of human ingenuity, and to the timeless Swiss art of watchmaking. So gear up, strap it on, and let it be your guide on your next great adventure.
