this is a rare Jaeger LeCoultre Tank dresswatch from the 1960s in outstanding good original condition. The 25,5 x 25,5 mm steelcase seems to be unpolished, showing clearly all numbers and engravings on in and outside of the caseback. the matte black dial features beautiful indicies and hands in copper color. the handwound JLC caliber was checked through and is running strong and exactly. A great detail is the highly built plexi that covers the dial which reminds as about the famous brutalist architecture from the 1960s. The JLC comes on a new black leatherband.
