The Soprod caliber C125 automatic movement pictured above and below is from an Oak and Oscar Sandford watch.

Soprod is a division of the Festina group.

According to John who submitted this movement, he says:

Difficult to find a lot of information on it. Oak & Oscar claims to be the sole user of the movement, and it could very well be true.

He also mentioned that the caliber C125 may have been based on the Soprod C105 or developed with Seiko 4L. If you have more information on this, please let the community know below.

When asked about the quality of this movement for daily wear, mrvarmint on Reddit says this:

Roughly equivalent to ETA 2893-2, exact same size, so it will be the ebauche found in a lot of formerly-ETA-supplied budget GMTs. Has a few extra jewels, not sure where though.

Function, fortunately or unfortunately, is the same as ETA 2893-2 with quick-set 24H hand rather than quick-set local time (as on a “true” GMT), because the GMT module is built on what would be the day module.

No complaints of Soprod, some anecdotal advantages in the manual winding works, biggest concern is that they’re relatively untested, but I wouldn’t be opposed to buying one for myself

I’ve been waiting for someone to post a Soprod movement. I just learned about them recently but there isn’t a lot of information on the Net. Is this based on an ETA movement? What would be a better alternative to ETA, a Soprod like this or the Selitta?

Selitta is a direct replacement / clone of ETA. The reason – from what I’ve gathered – is that ETA will limit sales to Swiss companies only.

Oak & Oscar never intended their watches to be “affordable” and chose to pursue a certain level and style for the watches. According to this page, Soprod will build movements to order (http://soprod.com/recherche-developpement/) so the C125 may literally have been built for O&O and then released to other companies later.

Here: Here: http://www.europastar.com/watch-knowledge/1004087450-mechanical-who-will-succeed-eta.html kind of infers that a basic A10 or C125 is on par with high end ETAs.

Ah, here is the review that mentions the C125 is exclusive to Oak & Oscar.

Another horseshit Hodinkee article. This caliber is not exclusive to Oak & Oscar by any means. https://www.hagerwatches.com/gmt-specs/

And I’ve been loving my Hager GMT “Stormtrooper.” It’s my main go-to watch for daily wear and traveling. The thing keeps amazing time.

I like the start cutouts in the oscillator.

Hager Watches say they use the SOPROD C125 Automatic movement in their GMT watch. Here is the link:

The base movement is the Soprod M100 (formerly A10) with a 0.5 mm thick dual-time module added on top, raising the stem height from 1.5 mm to 2.0 mm and the movement thickness from 3.6 mm to 4.1 mm.

The C125 has been showcased by Soprod as early as 2013. Oak & Oscar was established in 2015, at least two years after Soprod was advertising this movement.
