Never used Vintage Concord Quartz Swiss Luxury Watch

This Concord wristwatch features a black band marked "GENUINE EXPO-CALF" and a distinct exhibition case back. The band is labeled as 12mm and appears to be black leather. The watch case back is transparent, showing the inner movement. The back is engraved with a specific serial number: 17 61 268. Concord is known for luxury Swiss timepieces. Based on the serial number 17 61 268 and the distinct design elements on the case back, this watch belongs to the iconic Concord Saratoga series. This is a vintage Concord Saratoga, a flagship luxury sports line originally introduced in the late 1980s and early 1990s. The Engraving: The signature circular emblem in the center of the exhibition crystal features the year 1991. This denotes either the production period or a commemorative milestone for this specific iteration of the Saratoga line. Case Details: The numeric code 17 61 268 serves as the unique model reference and serial number identifier used by Concord to track production records. Never used needs battery.
