SWISS MADE VS SWISS PARTS:
According to Ronda, there are two versions of this movement: a gold plated Swiss Made version and nickel plated Swiss parts version. The Swiss Made version has 13 jewels and the Swiss Parts has 6 jewels.

POWER SAVING FEATURE
The battery is claimed to last about 54 months in normal conditions, but if you are not going to wear your watch for a while, the 5030.D has a power saving mechanism when the stem is pulled out stem (aka hacking function). Reduction of battery consumption approximately 70%. It is not advisable to leave the chronograph second hand running because it will drain the battery faster and put more wear and tear on the gears.

CHANGING THE BATTERY:
The wishbone or Y clamp has two prongs that are held into the case on one end and is held down by one screw on the other end. Be very careful when removing the screw because the clamp basically becomes a spring when it is loose and will catapult the screw across the room! The screw is very tiny and will be difficult to find. You can use a finger cot to hold the battery and clamp in place while removing the screw, or a piece of Rodico to hold it in place.
