The Longines Column-Wheel Chronograph, equipped with the self-winding cam-operated chronograph caliber L688.2, is Longines' masterpiece. $2500 Shipped to the Continental US. PayPal, Zelle, Venmo. Almost mint condition, I really can't find any scratches or wear, but I didn't want to go as far as mint (but it looks pretty mint). Comes with everything box and papers, as well as a brand new Longines black alligator strap and its original brown one. \- L27424560 \- Swiss Made \- Black Dial \- Index Hour Markers \- Polished Stainless Steel Bezel \- Date Feature \- Chronograph Feature Large Central Chronograph Second Hand 30 Minute Counter Sub-Dial at 3 O'Clock 12 Hour Counter Sub-Dial at 6 O'Clock \- Small Seconds Sub-Dial at 9 O'Clock \- 54 Hour Power Reserve \- Self-winding Automatic Movement \- Longines Caliber L688 \- Guaranteed Authentic \- Certificate of Authenticity \- Manufacturer Box & Manual \- Polished Stainless Steel Case \- Black Leather Strap With Pattern \- Scratch Resistant Sapphire Crystal \- 30 Meters / 100 Feet Water-Resistant \- 39mm = 1 1/2" Case, 7" Adjustable Strap \- Fixed Bezel \- Sapphire Crystal Exhibition Case Back \- Push & Pull Crown \- Screw Down Case Back
