This is a Breitling B-1 in great pre-owned condition and as far as my knowledge, unpolished but don't know for sure. Unsure of service history or when the battery was last replaced but it is running properly with all functions working as they should. Comes with box/bakelite and original paperwork. Fits loosely on my 7.5" wrist with a lot of micro adjustments left and one extra link. Some info below. Case Size: 43.0mm Case Thickness: 16.5mm Dial Color: Blue Caliber: 68 Water Resistance: 50 meters Lug Width: 22mm $1550 net, shipped CONUS. Thanks!
