I just replaced the faulty movement in a watch I've had for a while. The original movement was stamped 2813G and the date wheel is like spokes on a wheel. I found out it is known as the 'big date' version. A regular 2813 doesn't align correctly with the window on the face.
The replacement movement I found runs nicely, is quite accurate but the reserve doesn't last overnight after normal wear. I didn't have this issue with the original movement.
Is there a more modern, or better version of the 'big date' 2813? Or is the movement I purchased likely to be faulty? Or is it possible I have somehow replaced it incorrectly?
Any thoughts appreciated!
