I recall reading somewhere (I can't locate it now but I did try) that Incabloc didn't actually make watches, but there was an agreement (or requirement of sorts) that their name be put on the dial in certain cases. Again I apologize as I can't find the article I read about this subject but I do recall that it mentioned watches with only "Incabloc" on the dial and that they could come from a variety of sources. Opening the watch and examining the movement could tell us more about the watch you have, but only if you are able to do that - if you do please post a photo.
As already noted the company produces shock absorbing mechanisms for watch movements.
