Caliber 763 VS 763E

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

Ronda categorizes the 763 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 763E page here, you will see the 763E without the E engraved.

How to tell is by looking at the color of the movement. The gold versions are caliber 763, the nickel (silver) versions are 763E.

Features:

• Repairable metal movement
• Power saving feature (pull out the crown to setting position to save 70% of the battery)

Accuracy

In their official documentation, Ronda claims an accuracy rate of -10~+20 seconds per month.

Replacements

Most of the replacements available online are the nickel plated 763E. Replacement prices for the 763E were found in the range of $4.95 – $6.95.
