MB&F founder Max Büsser and H. Moser & Cie. CEO Edouard Meylan have worked together for more than 10 years, mostly behind the scenes: Moser’s sister firm Precision Engineering AG has been MB&F’s supplier of balance springs. This year, the two independent brands step into the spotlight together with a stunning horological duet: two co-signed timepieces each incorporating signature elements of the other’s brand. Today, we focus on the MB&F effort.
The LM101 MB&F x H. Moser reinterprets “one of the purest” models in MB&F’s portfolio, the Legacy Machine 101, which eschews tourbillons and other high complications for a simple but visually arresting presentation of the time, the power reserve, and the balance wheel that gives the watch its life.
In the spirit of this minimalist approach, MB&F’s logo appears nowhere on the dial — which is available in four emblematic Moser fumé colorways: Red fumé, Green fumé, Aqua blue fumé, and the popular Funky Blue fumé. For only the third time in MB&F’s history, the 40-mm-diameter round case, topped by a domed sapphire crystal, is made of stainless steel.
Showcased in the dial’s center, and suspended over it, is the titanic balance wheel, fitted with a double balance spring by Precision Engineering AG, which displaces each spring’s point of gravity, reduces friction, and improves timekeeping precision. Both the time and the 45-hour power reserve are depicted on the dial by small hands.
The movement, visible through the sapphire caseback, differs visually from that of the original MB&F Legacy Machine, whose decorative finishes were courtesy of Kari Voutilainen, a revered independent watchmaker and one of Büsser’s go-to contributing “friends.” In this version, the movement’s more contemporary NAC treatment offers a different kind of beauty and one more in-line with mechanisms produced by Moser. The watch, here again limited to 15 pieces in each of its four colorways, will retail for $52,000.
