Need some advice on how to remove the seconds wheel between the movement, ETA 2890 A2, and the chronograph module in an Omega Speedmaster. I also need a service manual for the module. Oskar

try searching for ETA 2890 2 instead of A2 (or just 2890). The A2 is associated with the 2892. But manuals for DD chrono modules are rare based on my past searches.

Hi there,

Could you give us the calibernumber, this helps locating the technical manual.
