How to tell which movement is in my watch?

Some manufacturers will put “Ronda 763” in their specs even though the watch actually has a calibre 763E. This may not be deliberate since the caliber number is “763” on both variations. If you check the 763 page here, you will see a similar 763 engraving that is found on the 763E shown below.

How to tell is by looking at the color of the movement. The gold versions are caliber 763, the nickel (silver) versions are 763E. If you find a movement with 763E engraved, please send us a pic to add to this post.
