A. Lange & Söhne is reintroducing a bracelet option for its Datograph Perpetual Calendar, a feature that was previously rare and often added aftermarket. This move caters to collectors who have long desired factory-fitted bracelets on the brand's high-complication watches, referencing the historical partnership with jewelry maker Wellendorff.
The new Datograph Perpetual Calendar is available with a bracelet, addressing a long-standing collector desire for factory-fitted bracelets on Lange's high-complication models.
Historically, Lange bracelets were often produced by Wellendorff, leading to them being commonly referred to as 'Wellendorff bracelets'.
Early Datographs produced on bracelets carried new reference numbers, such as the 453 series for platinum models, distinguishing them from later versions.
Three correct bracelet styles are identified for the Datograph: straight-link with a beads-of-rice-style end-link, 'square link' with soldered lugs, and a 'dog-bone' style with flared links.
Wavy bracelets are noted as likely being fitted later and not original to Datograph models, though they were used on Langematics.
Platinum bracelets can be distinguished from white gold by the finish of the three squared-off links: brushed for platinum and fully polished for white gold.
