Blomman Mr Blue recounts a serendipitous encounter with a fellow watch enthusiast who presented a rare LeCoultre Chronograph E 2644. This post highlights the unexpected connections forged within the watch collecting community and the shared appreciation for uncommon vintage references.


The Jaeger-LeCoultre E 2644 chronograph is a notable vintage reference within the brand's mid-century sports watch offerings. It represents a period where external movements were integrated into JLC's catalog, providing robust and reliable chronograph functionality.
This reference typically features a 37mm stainless steel case with a screw-down case back, ensuring a degree of water resistance suitable for its era. It is powered by the Valjoux 72 manual-winding chronograph caliber, a widely respected movement known for its column-wheel mechanism. The dial is often characterized by a smoked blue finish with distinctive round luminous hour markers and large, round chronograph pushers.
For collectors, the E 2644 is valued for its clean, functional design, the presence of the Valjoux 72 movement, and its relative rarity, particularly with well-preserved original dials. Its understated aesthetic and mechanical pedigree make it a sought-after piece for those appreciating vintage chronographs from established manufactures.
Possibly my favourite LeCoultre Cronograph.
But this one is an exception for sure! Best Blomman
The E 2644 is really a little beauty. A few years ago I had the chance of meeting here in Buenos Aires a high rank representative of JLC for South America visiting my Country. He showed me the beautiful Gyro tourbillon he was wearing and I surprised him with my E2644 which I was wearing on the occasion. He was surprised to see it and asked me to photograph it with his phone to show to his colleagues in Swiss. Wouldn’t it be great if JLC would offer a dial like this in a modern timepiece? Of cour

... A watch like the Master Chronograph with a similar dial of the E 2644 instead. Cheers! Abel ( sans date of course!
