Longines Master Collection Chronograph Watch

Authentic Longines stainless steel men’s watch bought secondhand; kinetic self winding. Has a small ruby visible through the see through back panel. Model no: L2.629.4 — 40mm case size. Has been formally authenticated by local watchmaker (see last two pictures). Was told there are at least 37 jewels within the mechanism. Serial number and model number are visible on the back panel. Black leather band is a replacement (value of band is over $400 alone); I still have the original strap saved (in black alligator style leather, but it came apart near the watch face and needed to be replaced). Some small buffed scratches along the outer watch frame, no damage. All mechanisms working perfectly. This watch is currently listed at CAD 3,950 on the official Longines website
