The Caliber 1126/1 verses the Caliber 1222 SC

 
 By: AndyT : November 16th, 2013-08:02
I have  received a great photo from VC of the movement inside my 2005 VC Overseas which is being serviced (attached) and note the movement though both marked 21C appears to have a different Caliber number to the latest shown on the VC website - 1126/1 vs 1222.  Apart from the number difference, I would be very interested to know other differences of interest? regards  Andy





Different watches

Hi Andy,
The VC Cal 1222 is for the dual timezone version of the Overseas, rather than the simple auto.
By the way, the 21C refers to the 21karat gold outer weight on the selfwinding rotor. It isn't a caliber reference. This base caliber is the JLC, as they are sister Richemont companies, they share their expertise wink
Hope this helps.
Warm regards,
TIm

Thanks for responding

It's also the same movement as in the Malte Tonneau Dual Time (Cal. 1222)
Best,
Joseph

Good thread for me as I've always pondered the difference between the Cal 1126 of a few years back the 1126/1 and now the current 1226. 

Here is a pic of cal.1222 for comparison

courtesy of The Hour Lounge:

As far as the 1126 vs 1126/1 - the latter movement was uprated to 28,800 vph for higher claimed accuracy.  It was used, for instance, in the Ref. 47022 Chronometre Royal with COSC certificate.
Hope this helps smile

JLC CAL 889

THE BASE EBAUCHE IS THAT OF JLC CAL 889 WHICH IS A CLOCKWISE AND ANTI CLOCKWISE AUTO WINDING ROTOR(650-950 TURN A DAY) WHICH THE CAL 1126 PHOTO SHOWS AS IT HAS THE REVERSER ASSEMBLY(PART 52040) THE TWO SMALL WHEELS AT THE TEN O' CLOCK POSITION.

THE REGULATOR AND BALANCE WHEEL IS THAT USED ON THE JLC 889-AND THE CAL 1126 

CALIBRE 1222 SHOWS THE REVERSER ASSEMBLY MISSING(WITH BLANK) WHICH WOULD MAKE THE WINDING ROTOR WORK IN ONE DIRECTION ONLY

ALSO THE BALANCE WHEEL HAS VARIABLE MASS SQUARE SCREWS MAKING IT  FREE SPRUNG WITH NO REGULATOR.
