Why This Watch Matters Along with the stunning silver dial, this Longines offers a brilliant chronograph movement with a flyback complication. Brains and good looks, all at once! The Full Story When it comes to vintage chronograph movements, Longines has a comfortable seat in the pantheon as one of the greats (especially when a flyback complication is involved). It all started in 1936 with the 13-ZN, eventually evolving into the 30CH and the 530 calibers, two virtually identical calibers. Longines was not only renowned for being the first to present a flyback chronograph in a wristwatch, but also for how clean and instantaneous the chronograph action and reset was. Back in the early 1960s, the reference 7412-5 we have here did not forget to look dressy, with applied indexes and logo on its silvery dial. True to its main function though, the legibility of the dial is still very impressive thanks to the striking colorful scales around the perimeter. This is a quintessential mid-century chronograph if there ever was one.

The tachymeter and telemeter scales are crisp and easily legible, and the colored printing is still vibrant. The chronograph movement 530 works flawlessly and the caseback bears the trace of a service in November 2015. The case is sharp, but displays some scratches to the casebands, while the caseback shows deeper impacts. On the other hand, the straight lugs still present their bevels, indicating that this watch was probably never polished. Furthermore, the Portuguese import mark is also intact on the upper left lug.
