According to the Ronda website, there are two versions of this movement: a gold plated Swiss Made version with 5 jewels and nickel plated Swiss parts version with 1 jewel. See the Swiss made model in the video below. The pics are from a Swiss parts model.

Is this the same movement as the Shinola Argonite 705? If so , is the Agonote gold plated with Swiss parts / 5 jewels ?

We can see 4 jewels on one side of the movement; it would not be unreasonable to guess that there is one more jewel on the other side of the movement.

I have a Reform watch that has the 705 I believe. It’s the 1 jewel swiss parts. If I am wrong please correct me as I am trying to authenticate what I have. This piece was found at a thrift store and I cannot find it anywhere on the web

I’ve serviced one. The Roscani Paris. It uses the 705. It had the -ve battery prong snapped in two! Too tiny to reattach with solder ! Anyone had a similar Ronda with a bad -ve battery prong? Seemed it is easily broken.

Had to resort to improvise with a small folded Aluminium Foil of thin thickness to act as the prong. It works and a averted the need for a new 705.

Just wondering if spare batter terminal prongs are readily available anywhere.
