These JLC Based movements are similar. A significant difference is the surface treatment.
I haven´t opened my Mark XII never before and was curious to see the C.884/2 in comparison to the C.887.
And an opportunity for some photos.
Maybe some others are also interested to see the difference ?!

Thanks for the interesting comparison.
Techncially, there's slightly more than simply a finishing difference between the 884 and 887 movements. As Walt Odets reported:
Interestingly, the 887 is shown by IWC as the base movement from which the 884 was developed; a development, no doubt, to hold down the cost of the Mark XII, which is almost a few thousand cheaper than an equivalent Ingenieur. An examination of the two movements reveals that they share all but nine parts. The main plate, barrel bridge, train wheel bridge, pallet bridge, and balance cock are different because of the 887's gilding, perlage, and Geneva decoration. The rotor is different because of its gilding and finish, and by virtue of its platinum peripheral weight (in place of the 884's base metal piece).And three functional pieces--the center seconds pinion, cannon pinion, and hour wheel--also proved to be different. Seconds pinion. These parts, respectively, carry the seconds, minute, and hour hands. The hour wheel, covering the cannon pinion, is show at left. The tip of the center seconds pinion is just visible in the center. The dial of the Mark XII, as it turns out, is slightly thicker, and stands slightly further from the top plate. So these three pieces are slightly longer, about 0.3 millimeter. The seconds pinion is shown above right for comparative length, the original 884 (Mark XII) part on the left.

Thanks for the link, Michael.
Indeed a very interesting article. I haven´t expected that this topic turns into this depth.
Thanks Heiko and MF,
Too few of us ,collectors really know and understand the ticking motor inside and the differences that can explain the production cost and the quality of a movement.
Great post.
Kind regards,

Great post and excellent pictures as usual. Thanks Heiko and Michael.
Very interesting to see another "un"-decorated IWC movement in light of the recent CF3 discussion, thanks Hebe
Perhaps Michael in his own diplomatic way is trying to explain why the CF3 wasn't decorated and why other watches aren't?

Too much phantasy, so I put my copyright sign on MY image.
Thank you for the post Heiko, it is always a pleasure to see your pics here.
And pictures of the inside of a watch are rare here on the forum ;)
Thanks Tonny.
The skills to open the case backs of watches is essential for a vintage collector, because you never know what is inside :-)
And a look to the covers of the inner soft iron case.
Thanks Heiko, great pictures as always. You don't need to 'watermark' your pictures because your style is so distinct I can tell from a mile distance it's an original 'Hebe' ;-)
Groeten,
Bob
Thanks Bob.
Well, many years ogo I started producing image modules, because the internet speed was low and those modules are perfect for high image compression.
And good as well for abstract photos.
That gives the photos a characteristic touch.
