A skeleton watch for men is built on one premise: what the movement looks like matters as much as what it does. PINDU's Skeleton & Open Dial collection takes that seriously, and the P6618 and P6668 represent two distinct interpretations of the open dial philosophy. The P6618 exposes the mechanical movement through a rotating skeleton framework — gears, bridges, and the oscillating rotor visible from the front. The P6668 takes a different path: a sculptured wave-pattern surface that plays with light and depth rather than transparency. Both are automatic. Both will stop a room. This comparison tells you which belongs on your wrist.
P6618 — The Skeleton Rotating Dial: Mechanics on Display
The P6618 is built for the man who wants to see the watch work. Its open dial removes the solid face entirely, replacing it with a skeleton framework through which the movement's key components are visible: the gear train, the bridges, the balance wheel oscillating as the seconds pass. The dial itself rotates as part of the mechanism — a detail that transforms what could be a static display into something genuinely alive on the wrist.
The colour palette is dark and industrial. Deep greys and blacks dominate, with polished metallic movement parts providing contrast. It is a watch that rewards close inspection — the more time you spend looking at it, the more detail you find. This is the watch with visible movement for the collector who wants function and form to be inseparable. If you have ever turned a watch over to study the caseback, the P6618 gives you that view from the front.
Worn against a dark sleeve or a casual open collar, the exposed mechanical watch movement visible through the dial reads as a deliberate design statement rather than a technical curiosity. This is not a watch that asks you to take it on faith. It shows you exactly how it works.
P6668 — The Wave Dial: Movement as Art
The P6668 Wave Dial Watch at $299.99 approaches the open dial idea from a different direction. Rather than exposing the movement, it covers the dial in a flowing three-dimensional wave pattern — sculpted ridges that shift from silver to blue-grey depending on the angle and the light source. The effect is oceanic and abstract. This is the open heart watch philosophy applied through surface design rather than transparency.
The automatic movement beneath the wave surface keeps reliable time, but the dial is the statement. Where the P6618 says look at the mechanism, the P6668 says look at the surface. Both are legitimate points of view. The P6668 wears more versatilely across dress codes — the wave pattern reads differently under a blazer than it does under a t-shirt, and it works in both contexts without announcing itself too loudly.
For the man who chooses objects the way a collector chooses furniture — by how they sit in space and interact with light — the P6668 is the more considered choice. The mechanical watch movement visible beneath its surface is not the display. The surface itself is.

Which PINDU Skeleton Watch Is Right for You?
The decision comes down to what you want the watch to communicate. If you are drawn to automatic watches because of what happens inside them — the gear train, the balance wheel, the engineered precision — the P6618 puts all of that in plain sight. It is a skeleton watch for men who understand what they are looking at and want others to ask about it.
If you care more about how an object sits in space, how light moves across a surface, and how form can carry weight without complexity — the P6668 is the more considered choice. It does not announce itself through jargon. It announces itself through design.
Both carry PINDU's 3-year warranty, free tracked delivery, and official documentation on every order.
Are Open Dial Automatic Watches Practical for Daily Wear?
Yes, with the same care you give any quality automatic. Both the P6618 and P6668 are built for regular wear, not display cases. The open dial watch automatic movement in both watches winds from wrist movement throughout the day. If either watch is left unworn for more than 36 to 48 hours, simply rotate the crown manually to restore the power reserve.
Skeleton Watch for Men — Frequently Asked Questions
What is the difference between a skeleton watch and an open heart watch?
A skeleton watch typically removes most of the dial to expose the entire movement. An open heart watch cuts a window in the dial to reveal a specific portion of the movement — usually the balance wheel. The P6618 is a full skeleton, the P6668 is an artistic interpretation of the open dial concept that does not expose the movement directly.
Is a skeleton watch good for everyday wear?
Yes. PINDU skeleton watches are built for daily wear. The movement is sealed inside the case under the crystal. Avoid heavy impacts and the watch will perform reliably every day. The automatic movement winds from normal wrist movement continuously.
Does a skeleton watch need a battery?
No. PINDU skeleton watches are automatic — powered by the self-winding rotor driven by wrist movement. There is no battery, no charging, and nothing to replace. If you want to understand more about how automatic movements work, read the PINDU automatic watch guide.
How do I choose between the P6618 and P6668?
If you want to see the mechanical movement working from the front of the watch — choose the P6618. If you want a sculptural, artistic dial that plays with light and carries bold design presence — choose the P6668.
