Breguet 9517 (New with box and papers) — USD 13,500 on eBay

The Breguet Marine reference 9517 is a notable entry in the brand's contemporary Marine collection, which saw a significant refresh in 2018. This reference represents Breguet's modern interpretation of a sportier watch, while retaining the brand's signature aesthetic codes and high-horology finishing. It is designed to offer a robust yet refined option within the Breguet catalog, appealing to collectors seeking a versatile timepiece with a strong horological pedigree. The Marine line, in general, stands apart from the more classic Classique series by its distinct case shape and dial treatments. This particular reference features a case crafted from a precious metal, typically rose gold or white gold, with a fluted caseband characteristic of Breguet. The dial often showcases a wave-pattern guilloché, a nod to its maritime inspiration, and is protected by a sapphire crystal. The movement housed within is an automatic caliber, visible through a sapphire caseback, offering a substantial power reserve. The design emphasizes legibility and a balance between traditional craftsmanship and contemporary styling. For collectors, the 9517 fits into the broader narrative of Breguet's strategic evolution in the late 2010s, focusing on consolidating its collections and introducing considered novelties. It appeals to those who appreciate Breguet's technical prowess and finishing but desire a watch with a more dynamic presence than its traditional offerings. The availability of different metal and dial configurations allows for personal preference within this well-defined segment of the brand's output.
