A compact and affordable triple calendar? Yes, please, the JPW Moonphase Triple Calendar

There’s a simple rule in the watch world, the more complicated a watch is, the more expensive it tends to be. Brands need significant R&D, and managing the sheer number of components is challenging, especially when everything has to fit into a small case. I’m not saying larger watches are “easy” to manufacture, but size can make certain complications less demanding to package.

That’s where quartz movements come in, they allow brands to offer a more approachable price point and let enthusiasts enjoy complications that would be extremely difficult, and expensive, to achieve mechanically.

Even so, there aren’t many options for classically styled, complication heavy quartz watches. For some reason, when it comes to quartz, makers often focus on sports chronographs or divers. But what if you could find a traditionally sized watch with details that evoke the old world of watchmaking, using unusual materials, at a price that costs less than your average G Shock? The first question that comes to mind is, what about the quality? And the second is, how did they do it?

Japan Precision Watch is a company I stumbled across while scrolling on Instagram. They posted one of the most striking dials I’d seen, black mother of pearl in what looked like a compact stainless steel case. It seemed too good to be true. After a couple of messages, the team at JPW kindly sent me their latest Moonphase Triple Calendar for some hands on time.

As soon as I opened the box, I was impressed. The design, the size, and most importantly, the quality all felt spot on. Let’s take a closer look at the rebirth of the classic dress watch.

The specifications

The first thing that drew me to the Moonphase Triple Calendar was the size. Most comparable watches with this level of complication are at least 38mm, and they often feel large and bulky. That’s not the case here. The JPW Moonphase measures 36mm in diameter, which is outstanding. It comes in a fully polished, double step case that not only wears beautifully, but also adds an Art Deco flair.

Fitting a triple calendar into 36mm is a real challenge because there’s a lot of information to display, but JPW handles it admirably.

The pointer date hand, with its red half moon tip, looks fantastic. The moonphase disc features a guilloché style pattern that stands out nicely against the black mother of pearl dial, which works as a subtle but elegant canvas. Diving more into that pattern called Seigaiha, is a traditional Japanese design of layered, repeating waves arranged in neat semicircles.

Its name means “blue sea and waves,” and it visually suggests calm water stretching into the distance.

The design often symbolizes peace, good luck, and a wish for enduring, steady life.

It’s commonly seen on textiles, ceramics, and kimono, ranging from subtle indigo to bold modern colors.

All of that detail and add the polished, elongated leaf hands, the month and day displays, and applied Roman numerals, and you can see how easily this design could become cluttered. Fortunately, it doesn’t. A central railroad minute track improves clarity, and overall the layout is balanced and legible.

The user experience is equally strong. The crown and correctors handle the moonphase and calendar settings, and everything is intuitive and easy to operate. Accuracy is rated at ±20 seconds per month, which makes it a genuinely practical daily watch, something that’s not always true of calendar and moonphase pieces. And unlike many moonphase watches, I actually like seeing the seconds hand ticking, with so much information on display, it’s reassuring to know at a glance that the watch is running.

To make all this possible in such a compact case, the JPW Moonphase uses the Miyota quartz Cal. 6P80, an excellent choice that helps keep the size under control.

On the wrist

The JPW Moonphase isn’t just compact in diameter, it’s also slim and well proportioned. The case is 9.9mm thick and under 42mm lug to lug, making it a great unisex option and a natural match for this classic complication. On my 6.25 inch wrist, it’s an undeniably perfect fit, and I’ve really enjoyed wearing it.

Legibility was clearly a priority. In a watch this small, with this much information, it would be easy to get wrong, but JPW nailed it. The contrast between the mother of pearl and the polished elements keeps the composition crisp and readable. It’s functional and beautiful at the same time.

I wore the JPW Moonphase to the office, where it feels completely at home. The 18mm black leather strap places it firmly in dress watch territory, and there’s no denying its elegance. The convenience of having a watch that displays so much information, and is always set, is genuinely enjoyable. A grab and go triple calendar, this one actually is.

Concluding thoughts

I haven’t even mentioned the best part yet, the price. The JPW Moonphase costs £190, which is outstanding value, there’s really not much else like it.

This watch combines premium looking materials and strong finishing with a compact, wearable design that suits a wide range of enthusiasts. If you’re in the market for something different and classically styled, this is a watch that won’t disappoint. JPW also offers mechanical models, which are impressive in their own right, but for me, this is the one to have.
