You already know what a watch dial is (right?). If you need a refresher on the fundamentals, our Watch Dial 101 guide covers the basics well.
This post picks up where that one leaves off.
Here, we're going deeper on the specific types of hour markers (called indices) and the dial styles that don't use markers at all, like open dials and skeleton dials. Once you understand these details, the difference between two analog watches that look similar at a glance becomes a lot clearer.
Let's dive into one of our favorite topics... watch dials.
Why Indices Matter More Than You Think
Watch indices do more than mark the hours. They define the visual weight of a dial, communicate the watch's intended use, and signal where a piece sits in terms of craftsmanship and price.
A flat printed marker and a fully applied metal baton can both mark 12 o'clock, but they create an entirely different experience on the wrist.
Understanding what you're looking at helps you make a better buying decision and gives you a real vocabulary for talking about watches.
Flat Print Indices
Flat print is the most basic form of dial marking. The indices are painted or printed directly onto the dial surface and sit completely flush with it. There's no texture, no shadow, and no dimension.
Done well, flat print can look intentionally clean and graphic. Done cheaply, it can look thin and insubstantial.
Flat print works best on minimalist designs where the goal is an uncluttered dial. It's also common in watches where a strong color or textured dial surface is meant to be the visual centerpiece rather than the markers themselves.
The trade-off is that flat print indices tend to have less visual pop in varied lighting conditions compared to raised alternatives.
Up-Print and Up-Label Indices
Up-print uses multiple print passes to build up the marker slightly above the dial surface, adding a subtle sense of relief and depth without going fully three-dimensional.
Up-print is a step up from flat print in terms of visual presence, and a good up-print can catch light in a way that adds refinement to a mid-range watch.
Up-label takes this a step further by using a die-cut metal piece to achieve more pronounced relief than printing alone can create. The result sits between a printed marker and a fully applied one, both in terms of cost and visual impact.
Both techniques are used to add perceived quality to a dial without the manufacturing complexity of applied markers.
Applied Indices
Applied indices are physically separate pieces attached to the dial through small holes in the dial base. They stand off the surface, catch light from multiple angles, and immediately communicate a higher level of craft and attention to detail.
This is the execution you'll see on well-made dress watches and sport watches where a premium feel is a priority.
The shape of applied indices carries its own meaning:
- Baton markers are the most versatile, clean rectangular bars that work across casual and formal contexts.
- Sword or dagger indices taper to a point and lean vintage or aggressive depending on the overall watch design.
- Dot indices are circular and typically appear on sportier or more minimal pieces.
Almost all applied indices can be filled with lume, a photoluminescent material that allows the markers to glow in low light, which matters a great deal on a dive watch or a daily driver worn through evening hours.
Stamped Indices
Stamped indices are pressed directly into the dial material itself rather than sitting on top of it. The marker becomes part of the dial base, sometimes then filled with flat print or up-print to add color or contrast.
Stamping is often used when a brand wants a marker with a custom shape or a more integrated, tactile quality.
Numeral Styles: Arabic, Roman, and California
Beyond how markers are applied, the style of the marker itself changes a watch's entire personality.
- Arabic numerals (1 through 12) are the most legible at a glance and work across casual and sport contexts.
- Roman numerals (I through XII) read as formal and traditional, and carry a heritage association that works well on dress watches and vintage-inspired pieces. One reliable detail to look for: most watchmakers use "IIII" rather than "IV" at the four o'clock position, a convention that dates back to clockmaking tradition and serves a visual balance purpose on the dial.
- The California dial is worth its own mention. It combines Arabic numerals at the bottom half of the dial with Roman numerals at the top, creating a distinctive split-style that's immediately recognizable and has strong vintage associations. It's a polarizing look but a deeply intentional one, and it appears across a range of field and dress watch designs that lean into their heritage.
Open Dials (No Indices)
An open dial removes hour markers entirely. There are no numbers, no lines, no dots. The hands move across a completely clean dial surface. This is the most minimal and arguably the most confident design statement a watch can make, because it forces everything else, the handset design, the dial color, the texture, to carry the full visual weight.
The practical downside is real. Without indices, telling the time quickly requires more effort and familiarity with the watch. For someone who checks their watch dozens of times a day in fast-moving situations, an open dial can become a minor daily frustration.
But for someone who wears a watch primarily as an object of style and occasionally glances at it in relaxed contexts, the trade-off is worth it. Open dials reward patience and deliberate wearing habits.
Skeleton Dials
Skeleton dials take a fundamentally different approach than any marker-based design. Instead of decorating a dial surface, the dial material is cut away almost entirely to expose the mechanical movement underneath. Gears, springs, and the escapement become the visual content of the watch face. It's watchmaking as theater, and when executed well, it's genuinely impressive.
The legibility trade-off on a skeleton dial is significant. Your eye has to find the hands against a complex, moving mechanical backdrop rather than a clean flat surface. Some skeleton designs address this with strongly contrasting hands or a partial chapter ring to anchor the hour positions, but it's always a compromise.
The Nixon Spectra is a good example of a skeleton design that manages this balance, using the movement's visual complexity as the draw without completely abandoning readability.
Skeleton watches also tend to be more demanding in terms of maintenance awareness. Because the movement is visible, any dust, moisture, or degradation inside the case is immediately apparent rather than hidden behind an opaque dial. It's a detail that matters more over years of ownership than it does at the point of purchase.
Choosing Based on How You Actually Wear an Analog Watch
The right dial type comes down to the context you're buying for.
If fast legibility is a priority, whether you're on the water, on the course, or just moving quickly through a day, applied indices with lume or bold Arabic numerals will serve you best.
If you're buying a watch that lives in a more relaxed, style-forward context, an open dial or a well-executed skeleton is a genuinely compelling option.
And if you want a watch that works across both worlds, a clean applied baton dial with a versatile handset is the reliable middle ground that most of Nixon's core lineup is built around.
The more you understand about what goes into a dial, the more deliberate your choices become. Every marker type is a design decision, and knowing what those decisions mean puts you in a better position to buy a watch you'll actually wear for years.
