References in the Grail Atlas catalog made in Saint-Imier.
Saint-Imier is a small valley town in the Bernese Jura, home to Longines since 1866, the manufacture at Avenue Agassiz has operated continuously, making it one of the longest-established single-address watch manufactures in Switzerland. Montblanc's Minerva manufacture is in nearby Villeret; the Minerva calibers (including the column-wheel rattrapante movements) predate Montblanc's 2006 acquisition and remain the high-end reference for the brand. The 15 catalog references from this cluster are primarily Longines Heritage and Spirit lines.
