MB&F x H. Moser LM101 & Endeavour Cylindrical Tourbillon


In this crowning expression of the ties binding H. Moser & Cie. and MB&F for more than ten years, Edouard Meylan and Maximilian Büsser have composed a duet recital in the form of an exceptional concerto for devotees of fine watch- making. For the first time in its history, MB&F is contributing to a Performance Art endeavour flowing in both directions in an entirely reciprocal manner. Within this framework, the two Maisons are co-signing a pair of creations whose DNA blends the main characteristics of each. A story of friendship between two men against a backdrop of shared values, for the pleasure of building and sharing, and then of jointly pre- senting the results of this extraordinary project.



H. Moser & Cie. and MB&F are both independent, human- scale Swiss companies. They are run by two passionate per- sonalities, longstanding acquaintances who both appreciate and respect each other on both a personal and professional level. The brands have in fact been working together for more than ten years, with Precision Engineering AG – a sister company of H. Moser & Cie. – notably supplying MB&F’s balance springs.  In a spirit of sharing and openness, while cultivating the notion of strength in unity, H. Moser & Cie. and MB&F have thus jointly created two models, available in several versions and issued in 15-piece limited series. By pooling their strengths, these two competing yet friendly brands are working to har- ness the combined strengths of talented artisans, entirely in keeping with the philosophy adopted by MB&F.


LM101 MB&F × H. MOSER The Legacy Machine 101 distils the very quintessence of mechanical watchmaking: the balance wheel, the power reserve and the passing of time. It is therefore no coincidence that MB&F has chosen to revisit this model – one of the pur- est and “simplest” in its collection – since it is indeed mini- malism that guided the creation of the LM101 MB&F × H. Moser model. The fumé dials borrowed from H. Moser & Cie. can thus be expressed in complete freedom, also enhanced by a refined bezel. Four fumé dials have been chosen for the LM101 MB&F × H. Moser: Red fumé, Cosmic Green fumé, Yas Marina Blue fumé and, of course, the famous Funky Blue fumé. Topped with a domed sapphire crystal, the case is made of steel, for only the third time in the history of MB&F.



LM101 MB&F × H. Moser is available in 4 limited editions of 15 pieces in stainless steel: Funky Blue fume dial, Cosmic Green fume dial, Red fume dial and a special edition with “Yas Marina Blue fumé” dial made for the retailer Ahmed Seddiqi & Sons.

Moser & Cie. has borrowed from MB&F the concept of three-dimensional movements, a strong element of the Geneva Maison’s identity, protected by a sapphire dome and featuring a one-minute flying tourbillon that rises above the main dial through a ventricular opening appearing at 12 o’clock. Benefiting from the expertise of its sister company Precision Engineering AG, H. Moser & Cie. has equipped its tourbillon with a cylindrical balance spring, the same as that developed by Precision Engineering AG for MB&F’s LM Thunderdome. Due to its specific shape, the cylindrical balance spring is far more difficult to produce and takes ten times longer to make than a traditional balance spring.



Endeavour cylindrical tourbillon H. Moser × MB&F is available in 5 limited editions of 15 pieces each in stainless steel: Funky Blue fumé dial, Cosmic Green fumé dial, Burgundy fumé dial, Off-White fumé dial and Ice Blue dial.
