Let's talk about the following actions. Luminox and traster are both Swiss movements, and their Chinese names are ronda and English names are Ronda. This is a Swiss chronograph movement and a jewel bearing shaft, so it is not the same grade as the Japanese chronograph movement at the same price!

Where's Elsa? The action is more complicated. Asia alone? In China? Thailand? They all have factory OEM, and their products are mainly supplied to the Asia-Pacific region? Its quality is also uneven, which are common in China? Isa? 5 15? isa7 15？ isa 1062？ The newly launched isa7004 will not be seen in Asia for at least a few years, but its cost performance is not as good as ronda's, so it can be packed one by one! ! )

In practical use, the quality of ronda movement is very good. What is the process? The material is also very fine, better than the common ISA movement and ETA material, and the quality can be passed down from family to family! The following remarks are purely handmade and hope to be adopted. Thank you.
