The Soprod 'Alternance 10' or A-10 is a high end mechanical movement, reputedly better than the ETA 2892: :drinks:
Soprod A-10 is a direct replacement for ETA 2892.
The width dimensions are the same between the 2892, 2824, and A-10, so the same hands and dials one used for ETA movements can also be used for the A-10, but the A-10 is 1 mm thicker than the 2824, so casing modifications may be necessary. It has a 42 hour power reserve and hacking seconds.
