Reflecting On Ten Years Of The Sensational De Bethune DB28

It’s been ten years since the De Bethune DB28 won the Aiguille d’Or at the Grand Prix d’Horlogerie de Genève. Effectively the “Best Picture” at the “Oscars” of watchmaking, this recognition placed De Bethune among the elite company of other Aiguille d’Or winners such as F.P. Journe, Greubel Forsey, Breguet, Audemars Piguet, A. Lange & Söhne, and Patek Philippe.

A decade removed from its Hollywood ending, the DB28 remains a grail watch in every sense.

Not that sense has anything to do with the DB28. It’s a wild experiment that pulses with the ambition of the Manhattan Project and radiates just as much piercing energy. Watchmaker and founding partner Denis Flageollet and his now-retired design lead, vintage dealer David Zanetta, planned the 42.7 mm titanium DB28 in a fashion designed to elicit love-hate reactions. Like the 1992 Dodge Viper, this is a concept machine that escaped unsullied by accountants, marketers, or MBAs.

And that’s its greatest strength.

To understand the genius of the De Bethune DB28, start inside and work your way to the edges. After years of experimenting with dial-side escapements and extravagant case backs, De Bethune put all the mechanical magic at the center of the DB28’s dial. A twin-barrel bridge blazes with “black” mirrored polish and “côtes De Bethune.” Similar to côtes de Genève, De Bethune’s stripes are laid down by abrasive wheels, but the wheel is reversed halfway through so that these unique waves point outward from each side.

Thanks to double self-adjusting mainspring barrels (patented), the DB28 boasts a still-impressive six-day power reserve. And unlike many watch brands of all sizes, De Bethune employs no compromised beat-rate tricks to achieve the 144-hour autonomy; this watch retains the industry-standard 28,800 vibrations per hour.

The mainspring barrels broach the edges of their seemingly Star Trek-inspired bridge and form prominent features of the dial; less prominent is the case back power reserve indicator. For good measure, this manual-wind machine employs a slipping mainspring to eliminate the threat of excessive winding.

Two triple Pare-Chute shock protection springs brace a balance bridge executed in full specular finish. The unique (and patented) antishock system elevates both the shock resistance and the chronometry of the watch.

In its 2011 form, the DB28 included an in-house balance wheel comprised of solid silicon with a white gold rim. Aside from its spectacular appearance, this wheel resists temperature-driven timing drift, maximizes mass in the balance rim, and reduces the aerodynamic drag of the wheel.

A hand-shaped hairspring consists of two elements bound together; they achieve the concentric “breathing” of an overcoil hairspring without the thickness or shock susceptibility of such a spiral.

The remainder of the DB28 dial is a combination of mechanical and aesthetic fixtures. Polished titanium cabochons grace the hour track, while a concave silver chapter ring provides a reference for reading the minutes. At the base of the dial, De Bethune employs its spherical moon phase display with a precision of 1,112 years between necessary corrections. One half of the moon sphere is fired blue steel, and the other is white palladium. And, yes, it’s patented.

Externally, the DB28 is a radical departure from conventional watch design. “Floating lugs,” first employed in 2008’s DB26 Perpetual Calendar, achieved immortality on the DB28. This system offers up to four millimeters of lateral compression. Like the wings of the Grumman F-14 Tomcat, De Bethune employs a variable geometry system that adapts to conditions – in this case, on the wrist. Several different lug sizes are offered to achieve lug-to-lug spans as disparate as 47 mm and 58 mm.

And unlike most luxury brands, De Bethune is amenable to retrofitting components for original and subsequent owners during mechanical service.

The fit is outstanding, and most collectors encountering a DB28 for the first time comment on the svelte 11 mm thickness. Not only does it sit as low as a dress watch, but the grade five titanium ensures a light and comfortable feel on the wrist.

Despite appearances, the DB28 is refreshingly compact for an extravagant design from a brash independent brand. Monsters from indie haute horlogerie mainstays like Richard Mille, Greubel Forsey, and MB&F generally wear as large as they look. But the DB28 is a joy even on a petite wrist, and a momentary encounter reveals unanticipated unisex potential. Taste and confidence – not wrist size – are the limiting factors for potential DB28 owners.

As of 2021, De Bethune can be described as a brand that builds nothing but “grail” watches. This term, invented eons ago by the online watch community, is overused. But when a watchmaker makes only around 200 watches per year, resolutely plows money into pure science R&D, and designs watches with a Blade Runner sensibility, the shoe – or the watch – fits.

De Bethune only builds grail watches; the DB28 was the watch that made it official.

    Tim, in an age of extraordinary hype, this is a fed case …” It’s a wild experiment that pulses with the ambition of the Manhattan Project ” ! Holy crap! I mean….really !?

      In Tim’s defence he has been wildly enthusiastic about this brand since day 1, and that probably goes some way to explaining the WB investment rather than vice-versa, even though I don’t quite see the attraction of these myself. Having said that though and allowing for the disclosure, I’m not sure Tim is the most appropriate person to be penning this article. A large part of the widespread respect and affection for Tim comes from his perceived honesty and independence, but some who are not familiar with his history might draw less than favorable conclusions from this endorsement. A difficult place to be…

        To be fair, this article could have been penned by any one of our writers — we all feel exactly the same way about this brand! And also to note: Tim is an employee of Watchbox, but not the owner and not an investor. He had no bearing on the current situation whatsoever. Because Quill & Pad is the honest publication it is, we felt it important to note he works for Watchbox, but we in no way believe he would not have written this article anyway. This is heartfelt, and could have come from any of us.

          Elizabeth, knowing Tim slightly I don’t for a second doubt his honesty, integrity or enthusiasm for the brand, but as you’re no doubt aware there is a widespread impression that WB has been manipulating the market on certain independent brands, and to many the DB deal looks like the latest evidence for this. So sometimes it’s just as important to eliminate even the perception of bias, and hence my concern that Tim doesn’t catch the flack which rightly or wrongly WB is likely to receive. Other than this I have no complaints about the article, and used my full name so as to avoid being accused of anonymous criticism.

            Hi David,

            Thanks for your understanding. You will see more articles under my byline in the next few days, and WB owns none of the featured brands. Then any reader can compare how I write about Greubel Forsey (for example) to my De Bethune feature and decide whether I favor the “house” brand. I also have a number of previous publications on Q&P for anyone who wants to cross-compare my tone when discussing other brands.

      Hi Ray,

      If you look at my online record of recorded video and written publications, you’ll see that I’ve been a supporter of this brand for ages. Also, if you check Quill & Pad’s own archive, you’ll find De Bethune photo studies that I published years ago long before WB invested. I’ve also written a ton of positive prose about Rolex and Patek, and it should be self evident that we’ll never own those. If you disagree with my assessment of this DB watch, I encourage you to try one firsthand. Seeing is believing.

        Hi Tim,
        It was the hype, who compares anything to The Manhattan Project with a straight face ? You lost me at that moment. Anything you say after that I have to take with a pound of salt . The watch by the way looks great ! You know, as watches go.

    Ray says:

    I agree, its like Elon Musk telling why the Tesla is like the Manhattan project !
    Its like he’s not aware ,that we are aware, he has skin in the game ? I know the watch industry treats everyone like idiots , but that hype right out of the gate, well , lets say I didn’t finish reading the promotion… I mean article.

    Oh my God!
    The distastefulness of the comparison was nothing to do with wristwatches.
    The “piercing energy” of The Manhattan Project killed at least 100,000 people and presaged The Cold War, M.A.D. and nightmares for all, over several decades!

    Maybe I should start a watch review with the simile “upon seeing this piece, I nearly collapsed like The World Trade Center”.
    Sound right, does it?
