Frank Muller long island perpetual calendar ref 1200

The Franck Muller Long Island Master Calendar ref. 1200 MC L is one of the brand’s most recognizable interpretations, where design and complication coexist in a direct and unapologetic way. The elongated rectangular Long Island case, with its soft lines and strong proportions, is paired with the classic Franck Muller dial featuring oversized, distorted Arabic numerals. In this full calendar configuration, the visual identity remains dominant while incorporating a more articulated technical layout. Technical specifications Case: 18k gold Dimensions: approx. 32 x 45 mm Thickness: approx. 11–12 mm Dial: black with applied Arabic numerals in Franck Muller style Movement: automatic Functions: hours and minutes day of the week month date moon phase at 6 o’clock Crystal: sapphire Strap: leather Rarity The ref. 1200 MC L is not rare in absolute terms, but it is not among the most commonly found configurations when equipped with a full calendar and moon phase. Most examples on the market show visible wear, particularly on the gold case, and the calendar mechanisms can be sensitive over time. Well-preserved pieces, with a clean dial and fully functioning complications, are less common than it may initially appear. It is a model that clearly reflects Franck Muller’s identity: more focused on design and wrist presence than on pure technical refinement, yet supported by a complication that adds real substance.
