The present lot is the wristwatch of the souscription set, numbered 139 of 300 pieces made, and it embodies everything a collector desires. The 37mm yellow gold coin-edged case is adorned with two different types of guilloche on the dial and subdials, presenting a wealth of information while maintaining a harmonious and legible design. The case is exceptionally well preserved, featuring crisp edges and hallmarks, and to the best of our knowledge, remains unpolished. It wears elegantly on the wrist, showcasing Breguet’s impressive ability to house such ultra-complications within a slim profile.

Powering this exquisite timepiece is the calibre 567, derived from the Lemania minute-repeating calibre cal. 399, with the perpetual calendar mechanism integrated on top. Aesthetically distinctive with its triple finger bridges and beautifully decorated with Côte de Genève, the movement and case back are signed with No. 139. A true grail piece of the 1990s, this watch serves as a testament to Breguet's pivotal role in Haute Horology and is a perfect way to celebrate the brand’s 250th anniversary this year.
