Hello, Omega does not have the 2610 movement. I can give you some reference about the 2500 movement.
The 2500 movement is divided into 2500A, 2500B, 2500C, and 2500D.
When the 2500 movement was first launched, there was a common phenomenon of stolen stops, which led to controversy in the industry about the stability of the movement. Therefore, the 2500 movement was later modified, ABCD.
The substrate of the 2500 movement is ETA2892A2. Originally, the power of the 2892A2 movement was weak, and Omega installed a coaxial escapement system on this basis. As a result, the phenomenon of stolen stops has always been a lingering shadow of the 2500 movement. The new 2500D uses a three-layer escapement wheel to ensure that the escapement system is not prone to slipping due to power problems, so that the movement will no longer have the problem of stealing. The 2500 movements currently on sale are all 2500D.
The 1.2500 movement uses a coaxial escapement system with a card-free hairspring balance wheel to enhance the stability and isochronism of the movement.

The 3.2500 movement uses 27 ruby ??bearings
The 4.2500 movement is one of Omega's patented movement models
Any movement They are all improved and polished on the basis of old movements. 2500’s changes to 2892A2 are still very large, so this 2500 movement should also be regarded as Omega’s own movement. If you have any other questions, please ask or send me a private message. I hope I can help you.
