Comparison of Epson YN55a movement and Tianma NH35 movement

Comparison of Epson YN55a movement and Tianma NH35 movement

Hi everyone,  Because the new crown pneumonia in Malaysia is not under control, the Tianmadu NH35a movement is out of stock in the overall market. The price can be said to be the rocket's rising speed, from 130rmb at the beginning of the year to 250rmb now. The key issue is that we can only find goods in small batches. So everyone is looking for a replacement movement that can replace the NH35a movement. We plan to replace some of the watches with the YN55a movement.

Let me talk about the similarities and differences between the two movements. Both belong to Seiko's movements. The NH35a movement is produced by Tianmadu, mainly for the mass market; the YN55a movement is produced by Epson, mainly for supply. The big brands have no external sales. According to the movement data, the two movements are basically the same, with some minor differences (the diameter of the movement is the same, the thickness difference is 0.05mm, and the position difference in Bazhong is 0.1mm). The purpose of replacement is achieved by changing a small part of the accessories.

Today we evaluate the YN55A movement, mainly through two aspects of comparison. On the one hand, it is compared with the functional structure and parts of the NH35a movement. On the other hand, it is the test of the YN55a movement.
