The Soprod caliber M100 is a Swiss made automatic movement that is based on the original Soprod caliber A10. This movement also shares similar characteristics with the ETA 2892-A2, such as dimensions and dial feet location, so it is considered to be a drop-in replacement or alternative for the 2892 (but not an exact clone).

Soprod, a division of the Festina Group, does not seem to offer as much detailed technical information on the M100 as they did with the previous caliber A10. For more history and information about this movement, click over to the Soprod A10 caliber listing.

M100 Variations:

As with the previous A10, the M100 is available in several versions:

  • M100 – Three hands with a date.
  • M100 Balancier Visible – Open balance wheel at 6:00, three hands, no date.
  • M100 Squelette – Skeletonized dial, three hands, no date.

In Soprod’s own words:

“Soprod produces its Swiss Made movements and components at its own sites in Reussilles, Le Sentier, Maîche, Muriaux, Saignelégier and Sion. Thus we guarantee the complete control of work of our production.” -Soprod

Does anyone know “How” Swiss made these movements are? In other words, what percentage of the movement is actually Swiss? Thank you.
