For collectors seeking something truly special, the catalogue offers a rare trio of Patek Philippe Calatrava models – a line that has become a symbol of minimalist elegance, conceived according to the Bauhaus principle “form follows function”. The Ref. 5107J-001 (lot 110, €10,000–15,000) in yellow gold stands out for its 37 mm case, sculpted lugs and screw-down crown with protective shoulders, offering a perfect balance between classic refinement and modern style. The Ref. 3591 (lot 1100, €4,000–8,000) from the 1970s bears the double signature Patek Philippe and Hausmann & Co., a detail attesting to its historical provenance, with a yellow gold case and blue dial that highlight its sophistication. Finally, the Ref. 1513 (lot 1099, €2,800–4,600) from the 1940s pairs a rose gold case with a matching salmon-toned dial, presenting itself as a unique piece for those in search of more refined vintage elegance.
