Well, I would say the 1326 is equal to JLC movements at this price range, it was developed as a Valfleurier (Richemont), developed for/with Cartier (1904 MC) by Master Watchmaker Carole Forestier-Kasapi and in this version, assembled, finished and decorated by VC.
I owned the Jaeger LeCoultre Master Control but I have sold it after 1 year. it was not for me. Very plain watch, no lume, very light. Dial is nice in pictures and video but in person after a while it is lack of personality to me. I replaced it with a GS GMT and it is definitely a better watch to me, at least better finishing of the case and dial
I love sector dials. I sourced the JLC in the secondary market at a great price. I went to view it and loved it but I wanted to have a few days before deciding on the purchase as I already have the VC in rose gold and didn't know if I wanted another sector dial watch. Went back for it and it was sold. I wished I had purchased it now 😫
You mentioned that VC is bigger than JLC. Which is true based on actual size but if you put side by side like at the start of the video the VC looks smaller due to the case details and dial size. And the JLC dial looks flat and lifeless. But anyway not fair comparison because there is a price difference.
The date on the VC looks very cheaply done, more of an after thought really. JLC great value for a full in house movement from arguably a brand that should be in the holy trinity
