The Heritage Dive Chronograph,a watch cteated from Heritage collection,it is a pretty rich trove of timepieces that offer pretty great value in one form or another. This watch is a 1960s style; like its mate, the time-only Longines Heritage Diver it is based on a model Longines originally produced in the pre-quartz era.
Both the old and the new versions share an inner rotating bezel, controlled from a crown located at 10 o’clock. Probably the biggest difference between the two is the movement; the original was driven by the Valjoux 72, everyone’s favorite tractor/go-to chronograph movement from the post-war/pre-quartz era; the new version’s powered by what Longines calls the L651, which based on the different level of the chronograph pushers and crown, appears to be a modular chrono of some description. In any case, it ain’t a Valjoux 72.
One doesn’t really hold that against the watch, though, as at this price point in general you don’t find in-house movements in any case (an alert reader has pointed out that a notable exception is the Seiko Brightz series of automatic chronographs. –ed.) Probably a more valid point of comparison would be another fan favorite, the IWC Portugieser Chronograph, which comes in at a higher price point with a Sellita version of the venerable 7750
