Caliber 763E VS 763

According to the Ronda website, there are two versions of the caliber 763. The movement listed here is a 763E which is nickel plated EOL with 1 jewel. The caliber 763 is gold plated with 5 jewels.

Ronda categorizes the 763E as part of their Normtech line, while the 763E is listed as a member of the Powertech line of movements.

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 caliber 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.

I had no idea that a Swiss movement could only cost a mere $5.00. Thank you Caliber Corner guys for for teaching me so much about watches on your site.

Hello, I bought a second hand, quite old I think Baume et Mercier watch which I think contains the 763E movement. Do you think that an old b&m watch could contain a movement like this or is it more likely a good replica? ( everything else I can’t fault. Thanks.

One more option to add is that maybe it’s a real watch that had some issues with the movement and they swapped it for a Ronda 763E.

Thanks for the reply, if that were the case do you know what that would do to he value? Cheers

I’m no expert, but I would say the value would plummet. Be careful trying to resale it because it could look like you’re trying to sale a watch that doesn’t have the original movement.
