Marc Obermann's acquisition of the Breguet Classique 4605/3015BA Ultra Plate offers a rare glimpse into a specific era of Breguet's history, marked by exceptional thinness and unique collaborations. His detailed examination highlights why this particular reference stands out, inviting collectors to appreciate the subtle yet significant details that define true horological artistry. This article delves into the nuances that make this timepiece a special find, particularly for those interested in Breguet's historical context and ultra-thin movements.








The Breguet Classique Ultra Plate represents the contemporary evolution of Abraham-Louis Breguet's original aesthetic philosophy, maintaining the brand's signature design codes while embracing modern ultra-thin construction. The 4605 reference sits within Breguet's core Classique collection, which has served as the foundation of the manufacture's offerings since the brand's revival under the Swatch Group. This particular execution demonstrates Breguet's commitment to classical proportions and traditional guilloché work that has defined luxury watchmaking for over two centuries.
The technical achievement of the Ultra Plate lies in its remarkably thin profile, achieved through careful movement architecture and case construction. The engine-turned dial displays Breguet's characteristic guilloché patterns, executed on rose-engine lathes that create the intricate geometric textures. The open-tipped Breguet hands and Arabic numerals follow the design language established by the founder, while the fluted case band and welded lugs demonstrate modern manufacturing precision. The automatic movement within maintains the brand's standards for finishing and reliability while achieving the slim proportions demanded by contemporary dress watch aesthetics.
In today's market, the Classique Ultra Plate occupies a crucial position as an accessible entry point into Breguet's world of haute horlogerie. The yellow gold case and classical styling appeal to collectors seeking traditional luxury without the complications that drive prices significantly higher in Breguet's catalog. While not possessing the same collectible cachet as vintage Breguet pieces or contemporary grand complications, the Ultra Plate serves as a solid foundation piece that demonstrates the brand's core competencies in case construction, dial work, and movement decoration.
