NOTES: Longines was known throughout the 1940’s, 50’s and early 60’s for manufacturing some of the finest in-house chronograph movements in Switzerland. In the opinion of many collectors, 13ZN and the subsequent 30CH, are the best in terms of technology and quality. The 13ZN caliber gave way to the 30CH chronograph, which was a slightly upgraded (though somewhat less desirable now) in-house chronograph, before Longines ceased the production of in-house chronographs in the late 1960s.
They began to source Valjoux 72 column wheel chronograph movements as an alternative to their in house movement and marked the V72 as caliber 330 internally.
This fine example includes the patented Vernier scale chronograph seconds hand. This was the first patent of its kind. Incidentally, the patent numbers for this chronograph are inscribed inside its case back along with its year of production.
This watch comes with an archives extract which confirms the movement was manufactured in 1968, but the inner case stamp of 69 indicates the watch was likely assembled and sold in 1969.
