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.
