Swiss watch manufacture Longines has been using the same sequential serial number system since 1832, and in that time they’ve produced over 51 million watches — all accounted for, one after the other, in either red leather-bound books of yesteryear or a modern electronic database. Your great-great-grandfather’s Longines pocket watch and the sporty blacked-out Longines diver that just sold in the Tokyo airport ten minutes ago are both in there, and Longines is able to service either watch by cross-referencing its serial number with their vast and meticulous archive of spare parts.
Referencing the Past

This meticulous organization plays close to stereotypes of the Swiss, but meeting Longines CEO Walter von Känel—who has been with the Swatch Group for 50 years and at the helm of Longines for over 30 years—proves that the deeper impact of the company’s taxonomic achievements is emotional and psychological. Those serial numbers seem to engender pride in the company’s uninterrupted production while also offering a clear perspective on its future.
The Longines Museum and the impressively bunkered archive that feeds it house historically significant watches like Charles Lindbergh’s storied Avigation watch (a model Ameila Erhart also used), while the factory upstairs runs high-speed shipping robots and two cutting-edge ETA movement manufacturers to produce millions of watch annually. The past, the present, and the future of watchmaking, all stored beneath one roof.

Some of Longines most critically acclaimed timepieces come from their Heritage Collection, which draws on the archive to offer faithful recreations. The most recent of these offerings is the Heritage Classic, a no-date sector dial watch at 38mm based on a 1934 reference that’s prominently on display in the Longines museum. Despite the critical acclaim, it’s clear that Longiones doesn’t do the bulk of its trade in this category, but as trends continue to lean toward old-school watches, the brand promises to continue a steady supply of historically accurate reissues.
