Breitling SprintApollo XVII, the last manned moon landing to date, returns to Earth with 250 pounds of lunar samples
1972 Breitling Sprint ref. 2013, manual winding cal. Valjoux 7733 a very reliable movements that was produced between 1969 and 1978, 40.2mm. case. Love the case and bold colors of the dials. I have seen this watch is burgundy blue, green and orange.
Ultra-light Breitling Sprint from the early 70’s, the watch was positioned as a joggers watch, this is why it has a pulsometer scale.
This was a period of time when everyone was experimenting with different case finishes and production methods. Resin cases seem to be the precursor to modern synthetic materials like carbon fiber. It shows Breitling ‘s willingness to try out new materials.
Breitling has been a leading innovator in high quality stopwatches and chronographs and helped define how chronographs look and function until today.
Breitling launched the first wrist chronograph with a pusher at 2:00 in 1915, presented the first dual pusher wrist chronograph with pushers at 2:00 and 4:00 in 1933 and was one of the first manufacturers to recognize the need of early aviators for wrist watches incorporating such devices.
In 1942 Breitling introduced the Chronomat, the worlds first Smart Watch, a chronograph with a rotating logarithmic slide rule that allowed complex calculations with the turn of your fingers.
Throughout the 1930s to 50s, Breitling continued creating chronographs with different scales to suit different professions, such as tachymeters for production engineers and drivers, and pulsometers for doctors.
A tachymeter scale measures how fast an object is moving. The scale can be found either on the dial or in the bezel. Most tachymeters start at 400 and end at 60, but some models can show different numbers.
