The caliber which animates the "simple" Overseas (ref 47040) is a Jaeger-LeCoultre movment!
So, it's not from VC manufacture....but VC works this movment again (like many other brands/manufactures)
JLC manufactures extremely reliable and famous movements, so don't worry abut the quality of your future watch
For proofs, this same JLC889/2 is also assembled on many Audemars Piguet ("simple" RO...), Breguet (Marine -the old one-), IWC (Ingenieur), VC watches (the Overseas 47040, the Toledo's caliber is based on the JLC889, etc.), and JLC of course and many other watches!!!...each brand will work again the movment: 21carats gold rotor for AP....etc...etc...
The JLC 889 was invented in 1983...and still exist and assembled in current watches!
So really!!!...don't worry about the reliability of this movment!
If you decide to buy this very nice Overseas, you will pay for the VC quality...and the name
If you really wish a 100% "manufactured" watch...price are twice...minimun ^^
...This watch seems to be you "coups de coeur"!! So buy it if you can afford, you will not regret; perhaps you don't have a "pure" in-house caliber inside...but it's reliable...it's the essential no?
