MB&F HM N°3 ReBel, three-dimensional sculpture in limited edition
James Dean was a Hollywood Rebel Without a Cause; Billy Idol had a Rebel Yell; Star Wars had its Rebel Alliance; and now MB&F pokes the establishment firmly in its conservatively-focused eye with the HM3 ReBel. Whereas James Dean was the epitome of movie star bad boy, MB&F is the wild child of haute horlogerie; the lone biker in a black leather jacket when everyone else is wearing grey suits and driving Volvos. And unlike Dean, the HM3 ReBel knows exactly what its cause is: horological anarchy!
ReBel: R for right (hand), B for Black (case). The black-coated ReBel is a distinctive, rock ‘n roll mirror-image of the HM3 designed to be worn on the right wrist, as a few individualists out there are wont to do.
And like all true rebels, nothing on the HM3 ReBel is quite as it first appears, especially when you take a closer look behind its nonchalantly cool façade. Under the ReBel’s open black leather jacket – or to be more precise, its black PVD-treated white gold case – charcoal-coloured movement plates and bridges form a darkened backdrop to the resplendent flash of the 22K rotor as it speeds by.
Despite its anarchistic appearance and unorthodox right-wrist architecture, the HM3 ReBel has a serious side. This dynamic, three-dimensional sculpture is a highly technical wristwatch as well as a statement of attitude. The ReBel’s twin cones ergonomically indicate the hours and minutes, with the hour cone capped by a day/night indicator. The top caps of the truncated cones are brazed (not glued) to ensure maximum water-resistance and the red “hands” of the hour and minute indicators are cut by laser to obtain the incredibly high precision/minimum mass ratio the design necessitates.
White gold clover-head screws on top of the black case resemble rivets in an upmarket biker’s leather jacket, while the large, legible numbers of the over-sized date wheel around the rotor enable the date to be read off easily against a neat, engraved triangle on the case.
The rotor and oscillating balance on top provide a clue that the ReBel’s movement, featuring no less than 36 functional jewels and 304 components, is actually inverted. Turning the Machine over reveals the technical secret behind the powerful and superbly hand-finished engine: two large-diameter, high-tech ceramic bearings racing inside bright blue cages efficiently transmitting power up to the time indication cones and date wheel.
We think James Dean would have worn one; Billy Idol would have sang about it; and the Rebel Alliance would have fought for it.

MB&F Horological Machine N°2 SV The Final Editions [Limited Edition]
First launched in 2008, Horological Machine No2 revolutionized the world of haute horlogerie with its distinctive rectangular shape, flying buttresses, dual portholes and modular construction. The crystal-clear sapphire case of HM2-SV then took the revolution even further by offering unprecedented visual access into the meticulously hand-finished, 349-component engine powering the indications on HM2′s iconic twin dials.
But all good things come to an end and, after three very successful years, Horological Machine No2 takes one last bow on center stage with two final limited editions of 18 pieces each, both featuring sapphire cases: HM2-Black SV and HM2-Red SV close the HM2 collection, thus ensuring its exclusivity.
Synthetic sapphire watchcases are extremely rare for good reason. While sapphire retains its strength at high temperatures, has zero porosity and (below 300°C) does not react to acids, the very properties that make it so attractive also make it extremely difficult to mill, requiring sophisticated (and expensive) diamond tools to machine, followed by careful polishing to turn the opaque freshly cut or drilled surface transparent. The complex, three-dimensional form required for HM2-SV’s case, with its bevels, mounting holes, porthole cut-outs and embedded gasket track, pushed the limits of sapphire technology beyond what was thought possible. No less than 55 hours of milling, drilling and polishing are required just to create each sapphire case.
While both new final models are derived from the original HM2-SV, each has its own very distinctive identity.
HM2-Black SV features a sapphire case, black dials and a black PVD titanium baseplate that makes a strongly contrasting backdrop for the unique architecture of the HM2 Engine inside, which is framed by an electric green rubber gasket clearly visible through the transparent top. Turning the watch over reveals yet another splash of colour from the vivid green 22K gold winding rotor.
HM2-Red SV has its sapphire case black dials mounted on a regal red gold baseplate. The black dials, black rubber gasket and the rich red of the caseback provide a stunning juxtaposition with HM2′s silver Engine. Turning the watch over rewards the viewer with the sight of MB&F’s signature 22K red gold battle-axe rotor complimenting the red gold of the caseback.
The HM2 engine, developed by award-winning master watchmaker Jean-Marc Wiederrecht, features the world’s first mechanical movement offering: Instantaneous Jump Hour, Concentric Retrograde Minutes, Retrograde Date, Bi-Hemisphere Moon Phase and Automatic Winding. One highlight (of many) of the HM2 complication is the highly energy-efficient Jump Hour/Retrograde mechanism developed by Jean-Marc Wiederrecht, which uses his exclusive (and patented) asymmetrical-tooth gear wheels to ensure high precision and play-free functionality.
The sapphire case: Surprisingly, because it is largely unseen, the sapphire cases of these final editions are a substantial 3.6mm thick. Thanks to anti-reflective treatment on both sides – in itself no small technological feat to uniformly apply – the case becomes virtually invisible and allows for full appreciation of the myriad nuances of the complex movement. Eight mounting bolts traverse the sapphire plate like pillars, passing through the twin tracks of the rubber gasket sealing the sapphire case and caseback, add to the architectural nature of the three-dimensional case.
The case, with its flying buttresses, bolted portholes, was so complex – over 100 components go into its construction alone – that it could only be developed with an innovative modular method inspired by the Meccano sets of Maximilian Büsser’s childhood. And in line with best engineering principles, this modularity also simplifies future refurbishment of the case should it ever be necessary.
Technical Innovations: The principle technical challenge in developing the movement was ensuring that the jumping hour functioned both instantaneously and simultaneously when the retrograde minute flies back from 60 to 0. And not only instantaneously: without using excessive energy. The usual method of activating Jumping Hour indications is to store energy in the minutes before the change to power the jump; however, while this energy is being accumulated it takes power from the balance causing it to loose amplitude – an effect detrimental to time-keeping precision. Wiederrecht’s solution was as brilliant as it was simple: he designed a ingenious mechanism so that when the minutes fly back, a snail on the minute mechanism hits the hour star causing the hour to jump. The hour jumps instantaneously with the minutes because it is triggered by the minutes and, as the jump is powered by the energy of the minutes flying back, it has virtually no effect on the amplitude of the balance.
While the complications and functionality operate with maximum efficiency, with 349 components in the movement alone, there are no doubting HM2′s credentials as an incredibly technical tour de force.
The complication has another very special feature. Specific gears in HM2′s movement are manufactured to extremely high precision using Mimotec’s UV-LIGA technology. These gears mesh together with a virtually a no-tolerance/no-play engagement. Normally, gears interacting this tightly would bind; however, Wiederrecht’s patented asymmetrical-split-tooth gear design ensures this does not occur. The high precision of this gearing enables very accurate time-setting and offers high reliability.
To maximise the efficiency of MB&F’s already iconic battle-axe automatic rotor, one of the 22K gold blades was machined down to a razor sharp edge of just 0.2mm – a dimension that pushed the very limits of micro-machining!
While Horological Machine No2 is a high-tech machine of the 21st century, the quality and hand execution of the fine finishing is a showcase of the very best in traditional craftsmanship. Light flashing off hand finished mirror-polished surfaces and immaculate bevelling brings vivacity to the rich combination of colours, materials, shapes and textures.
Movement – Jean-Marc Wiederrecht/Agenhor designed functionality regulated and powered by a Girard-Perregaux base. Balance oscillating at 28,800 bph. 22K red gold battle-axe automatic winding rotor (green PVD coated 22K for HM2-Black SV). Number of components – 349 including 44 jewels.

MB&F Horological Machine N°3 Frog Zr, prestigiosa edizione limitata
Fino a poco tempo fa, la rana più rara del mondo era considerata la Isthmohyla rivularis, riscoperta nel 2008 nelle foreste pluviali del Costa Rica. Oggi, tuttavia, il posto di quella piccola rana arboricola nel libro dei primati è stato occupato da un nuovo anfibio con una pelle nera satinata sufficientemente dura da superare qualsiasi cosa presente nella giungla: Frog Zr di MB&F, in edizione numerata e limitata a soli 18 esemplari.
Zr è il simbolo usato in chimica per lo zirconio, un metallo di transizione che assomiglia al titanio. Un titanio agli steroidi! Solo per dare un’idea di quanto sia resistente lo zirconio, basti pensare che le lame e le pale dei motori a getto e delle turbine a gas di oggi possono sopportare le temperature e le sollecitazioni incredibilmente elevate da essi generate solo grazie ad uno strato ceramico protettivo in zirconio e ossido di ittrio. Il novanta per cento dello zirconio prodotto viene usato per i reattori nucleari, mentre le leghe di zirconio sono usate nei veicoli spaziali per la loro resistenza al calore estremo che si sviluppa al rientro nell’atmosfera.
Frog Zr è l’unico anfibio che può guardare le avversità direttamente negli occhi . . . e non abbassare lo sguardo per primo!
MB&F ha lanciato HM3 Frog per portare un po’ di allegria nell’alta orologeria. E certamente è riuscita nel suo intento e Frog Zr non fa eccezione. Sotto il suo esterno in zirconio apparentemente da duro, uno sfavillante rotore viola in oro 22 carati che gira animatamente nel quadrante con intriganti riflessi verdi e gialli manda un messaggio cristallino rivelando che Frog Zr ha anche un sano senso del divertimento.
Le semisfere che alloggiano le ore e i minuti di Frog Zr non sono lì soltanto per attirare l’attenzione – per quanto certamente lo facciano – ma consentono a chi lo indossa di leggere agevolmente l’ora da varie angolazioni senza dovere ruotare il polso. E, come nel caso dei suoi fratelli, anche Frog Zr è sostanzialmente diverso da HM3, poiché nel primo sono le semisfere in alluminio a ruotare sotto i cristalli di zaffiro, mentre nel secondo sono le lancette delle ore e dei minuti che ruotano attorno a dei coni fissi.
Le sfere delle ore e dei minuti sono realizzate in alluminio massiccio, scelto per l’ottimale rapporto forza/peso, con uno spessore di appena 0,28 mm e un peso sul quadrante di soli 0,5 grammi, riducendo pertanto al minimo il dispendio energetico per la rotazione. La realizzazione delle semisfere dei cristalli di zaffiro è stata altrettanto difficile, dal momento che la minima imperfezione dello zaffiro avrebbe prodotto uno sconcertante effetto di ingrandimento – e Frog Zr non ha certo bisogno di alcun aiuto da questo punto di vista!
Frog Zr potrà anche mostrare l’ora in modo divertente, ma non c’è niente di divertente nella meticolosa attenzione al dettaglio della perfetta finitura a mano del motore con 36 rubini e 304 componenti sincronizzato con alta precisione all’interno della cassa in zirconio space-grade. Si tratta di una cassa caratterizzata da dettagli attentamente studiati, tra cui viti con la testa a trifoglio, una freccia incisa che indica la data a caratteri grandi facilmente leggibile e un fondello che rivela i doppi cuscinetti ceramici che regolano le semisfere.
Anche se abbiamo detto che Frog Zr è estremamente raro, avremmo dovuto specificare che lo è sulla terra, perché lo zirconio è relativamente abbondante nelle stelle di tipo S ed è stato individuato nel sole e nelle meteoriti. Ma se lo volete a tutti i costi, non dovrete andare così lontano.
Frog Zr è in un’edizione limitata di 18 esemplari in zirconio con rotore viola in oro 22 carati.
