Open Tourbillon Watch — Blue Guilloché, Tonneau Case
INVENTED 1801 · STILL PURE THEATRE
You Can Watch The Heart Of It Beating
An open aperture at the centre of the dial, and inside it, the escapement — turning.
There is a hole in the middle of this dial. Look through it and you can watch the mechanism that keeps time — the escapement — held in a cage that rotates continuously, so gravity pulls on it evenly from every direction instead of dragging it out of time in one.
That is a tourbillon. It was invented in 1801 for pocket watches, and two centuries later it remains the single most theatrical thing a mechanical movement can do.
Most people will never own a watch where you can see the mechanism move. This is how you do it without spending five figures.
GUILLOCHÉ · TONNEAU · TEXTILE
Navy To Near-Black As You Turn Your Wrist
An engine-turned wave dial inside a blacked-out barrel case.
The tourbillon sits open at the centre of a deep blue guilloché dial — engine-turned waves cut in fine parallel lines, so the surface shifts from navy to near-black as the light crosses it.
Oversized Arabic numerals float around the outside, legible at a glance and dramatic at any distance. The case is a blacked-out tonneau — a curved barrel profile that hugs the wrist and keeps every eye on the movement.
It finishes on a black textile strap with contrast stitching: light, breathable, built for daily wear rather than a display case.
Mechanical Theatre, Staged In Five Acts
What it takes to put a beating mechanism on open display.
The Guilloché
Parallel waves are cut across the deep blue dial — fine enough that the surface reads a different shade with every degree of light.
The Aperture
The centre of the dial is opened — a decision that removes anywhere for imperfection to hide. Everything behind it will be watched, daily.
The Cage
The rotating escapement cage is assembled and set into the aperture, where its continuous turn becomes the face's centrepiece.
The Case
The curved tonneau is formed and blacked out — a barrel profile that follows the wrist and frames the dial without competing with it.
The Bench
The movement is regulated and timed, the numerals are checked under magnification, and every piece is hand-inspected before boxing.
2-Year Warranty. 30-Day Refund.
Wear it for a month. If it is not what you expected, send it back for a full refund — no conditions, no restocking fee.
Why A Tourbillon Stops Conversations
Quartz solved timekeeping decades ago. What it could not solve is this: the quiet thrill of a mechanism you can watch working — gears, spring and cage, turning in the middle of your dial all day. Five-figure houses charge accordingly for it. This one puts the same theatre on your wrist without the second mortgage.
THE FIVE-FIGURE LOOK, BENCH-TESTED
An open tourbillon aperture, a guilloché dial and a curved tonneau case — the recipe from watchmaking's top shelf, timed and inspected before it ships.

From The Owners
I catch myself staring at it
In meetings. At lights. The cage just turns, endlessly, and it is impossible not to watch. The guilloché is the sleeper detail — in the evening the dial goes almost black and the mechanism seems to float. Extraordinary at this price.

The tonneau shape wears superbly
I was worried a barrel case would sit like a brick. It is the opposite — the curve follows the wrist and it slides under a shirt cuff cleaner than my round 42mm. The numerals are properly applied, not printed. Quality throughout.

My first visible movement
Twenty years of solid dials and I finally understand the fuss. There is something grounding about seeing the thing actually work. Strap is light and comfortable, stitching is neat, timekeeping is well within what I expected.

Theatre is the right word
Bought as my wedding watch and it photographed beautifully — the blue reads almost black in evening light. One note: the open dial means you check the time a beat slower at first, because you get distracted. That is a strange complaint and I am keeping it forever.

Arrived in four days, boxed like jewellery. The moving cage is hypnotic and my phone gets checked far less now.

Frequently Asked Questions
What exactly is a tourbillon?
What exactly is a tourbillon?
A cage that holds the watch's escapement and rotates it continuously, so gravity acts on it evenly from all directions rather than pulling from one. Invented in 1801 — and still the most theatrical thing a mechanical watch can do.
Does the tourbillon make it more accurate?
Does the tourbillon make it more accurate?
It was invented for the vertical pocket watches of 1801. On a modern wristwatch its value is craft and theatre — a live mechanism on open display — rather than a measurable accuracy gain. Every piece is still regulated and bench-timed before it ships.
Is the dial really cut, or printed?
Is the dial really cut, or printed?
The guilloché waves are engine-turned — fine parallel lines physically cut into the blue surface, which is why it shifts from navy to near-black as light moves across it.
How does the tonneau case wear?
How does the tonneau case wear?
The barrel shape is curved to follow the wrist, so it sits lower and more secure than an equivalent round case, and slides under a cuff cleanly.
What strap does it come on?
What strap does it come on?
Black woven textile with contrast stitching — light, breathable and made for daily wear rather than the display box.
Is it water resistant?
Is it water resistant?
Rain, handwashing and splashes are fine. With an open dial we would keep it away from swimming, showers and steam.
