The “Swiss” marking on the dial and the small lume dots near 3,6,9, and 12 o’clock, indicate a primitive version of the Longines Diver, probably the most desirable vintage execution of this iconic 42 mm dive watch, and still produced by Longines to this day. The two cross-hatched crowns are characteristic of the Super Compressor case, where increasing pressure of the water actually tightens the case back, thereby increasing the waterproof resistance of the case – on this reference guaranteed to a depth of 100 meters. The dive time can be measured on the inner bezel, which is rotated by the upper crown, while the lower one connects to the small automatic caliber 19AS. Additionally, this diver comes with a Longines-signed, stainless-steel bracelet, very likely original to the watch according to the reference article here.
