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 with 1 jewel. The caliber 763 (Normatech) is gold plated with 5 jewels.
Some manufacturers will put “Ronda 763” in their specs even though the watch actually has a 763E. This may not be deliberate since the caliber number is 763 on both. For example, this pic is of a 1 jewel/nickel 763E, but the caliber number engraved on the movement does not include the E.
- Repairable metal movement
- Power saving feature (pull out the crown to setting position to save 70% of the battery)
In their official documentation, Ronda claims an accuracy rate of -10~+20 seconds per month.
The examples here are of a caliber 763E found in a Chronologia Pilot.
Replacement prices for the 763E were found in the range of $4.95 – $6.95.
