Precision Tourbillon
The tourbillon was invented in 1801 to solve a specific problem: pocket watches worn vertically accumulated positional errors from gravitational pull on the escapement. The solution was to place the entire escapement inside a rotating cage that completes one revolution per minute, averaging the positional error over time. Making one that works reliably, over decades, in a wristwatch case, is among the most demanding tasks in mechanical horology. This movement houses a flying tourbillon — no upper bridge over the cage, so the rotating assembly appears to float in the dial aperture. The cage weighs 0.3 grams and contains fifteen components, each machined to tolerances measured in microns. The escapement is adjusted to within two seconds per day in six positions. Power reserve is 72 hours. The case is 40mm, hand-finished in 18k white gold. The dial is grand feu enamel — a technique requiring multiple firings at 800°C that has no factory equivalent. Each dial takes a specialist three days to produce.

I have collected tourbillons for thirty years. The finishing on this movement is competitive with Geneva manufactures at twice the price. The anglage on the bridges is crisp, not approximated. The perlage on the base plate is consistent across the full surface. The enamel dial is exceptional — the depth of color on grand feu enamel is simply not reproducible by any other dial-making method.
The flying tourbillon is mesmerizing in person. Photographs do not capture the depth of the enamel or the way the cage appears to defy gravity when the watch is at an angle. The 0.3-gram cage weight is incomprehensible until you see fifteen components moving as a single coordinated mechanism at that scale. This is the piece I will leave behind — it is already the most asked-about item I own.
I understand technically what grand feu enamel requires — multiple firings at 800°C, the risk of failure at each stage, the color variation that means no two dials are identical. Seeing the finished dial in person makes the technical specification irrelevant. It is simply beautiful in a way that printed or applied dials cannot approach. The white gold case is an appropriate frame for it.
I set this watch against a GPS reference for thirty days across three temperature environments. It varied between +1.8 and -1.4 seconds per day — within the stated ±2 seconds. For a manually wound tourbillon adjusted in six positions, this is an honest specification rather than a marketing figure. The escapement is doing its job.
The movement, dial, and case are executed to a standard that few manufactures at this price reach. My note is that the travel roll that ships with the watch is leather-covered but not rigid. For a piece at this price, a custom-formed hard case in addition to the travel roll would better suit the value of what it is protecting. The watch itself earns full marks.
We are releasing a custom-formed travel case for this piece in Q3. It will be offered to all existing owners at no charge. The current travel roll was an interim solution — your note confirms we should accelerate the timeline.
A 72-hour power reserve on a manual-wind tourbillon means I wind it Sunday evening and it runs until Wednesday without attention. This is the practical specification that most manufacturers overlook while competing on other complications. The watch is always running when I pick it up. That matters more than I expected it to.
