JLC movement in IWC watches

I knew IWC used JLC movement in some of its watches in the past. I am interested to know what kind of IWC used JLC movement?

Thanks,

Felix

Off the top of my head, the Mark XII (although the later ones had an IWC-modified ETA movement, I think).

I'm sure there were others.

The classic Ingenieur had it -IWC modified the movement and even put a platinum tip on the rotor. Without checking, I think it was Ref. 3521. Also the small Portuguese used a JLC movement, as did the mecaquartz chronos.

As Mike pointed out, the Small Portuguese (ref 3531) had a JLC automatic movement. Here are some pictures of the watches and the movement.

I think the IWC GST Alarm used a JLC movement too. You can search the archives for details on that.

The Novecento ref. 3546 had a base movement from JLC where the IWC perpetual calendar module was added.

Indeed, the IWC GST Alarm used the Cal 917

See a write up of it here.

Thanks all for the prompt reply. There are quite a lot of watches were using JLC movements. Most of the names are the first time for me to hear. Thanks for the information.

Hi Stz, whichwatch, thanks for sharing the photos. This is my first time to see the 3521, 3546. They are very elegant watches. Thanks for sharing.... The all look very thin, especially the 3546, from a PPC prespective

Best Regards,

You can add also Ingenieur 3521/ 9239 with JLC 887/2 and by the way here you can get the info about all watches before year 2001 with indication of movements:
