The Ronda caliber 5050.E is a quartz chronograph watch movement. This caliber is part of Ronda’s Startech line of movements. There is almost no information about the 5050E online and it’s as if only Invicta uses it.
At the time of this post, it appears that the caliber 5050.E has been phased out and is no longer produced/supported by Ronda. Their official site does not list the 5050.E in the product list, nor is it listed in the user manuals section.
Some of the topics covered in this caliber listing:
Two Versions of 5050.E:
There are two versions of this movement: a Swiss parts version with 6 jewels and nickel plated finish, and a 13 jewel version with gold plated finish.
