1940s Longines "Stop Second Minutes Recorder" Rare Two-Tone Breguet Tachymetre Dial

This is a very rare silver two-tone Breguet tachymeter dial. This is a very rare two-tone dial with tachymeter indication around the periphery and Breguet indexes laid out in the center of the dial, which is very rare among stop-seconds made of GF material, which are often seen in simple designs. The design stands out for its sense of condensation and good balance, and the case back is round and bulging with a sense of weight despite its small size, making it a gem with an appealing presence that transcends its size. It is equipped with the famous Cal. 12.68z, which has many variations such as small seconds, center seconds, and simple chronograph. In addition to the archive, the watch comes with a full set of accessories, including a genuine leather strap and buskle.
