The Soprod caliber C125 automatic GMT movement. It is Swiss made with 25 jewels and a run time of about 42 hours on a full wind. This caliber is based on the Soprod A10-2 (now known as the M100), with a GMT module. Soprod is a division of the Festina group.

Caliber Commentary:

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… Read more »

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

Francis Jacquerye

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.

As others have noted, from the A10 calibre, which is based on the Seiko 4L25 movement, design licensed to Soprod.

Grovana’s Revue Thommen GMT is using this movement. Most of the advertising for the watch still lists ETA 2893-2 as the movement. A look through the case back shows the 25 jewel movement. The ETA 2893 is 21 jewels. The Soprod A10 is also being offered in some Steinhart watches such as the Ocean One Premium 500 titanium since ETA is selling only to the Swatch group.

I bought one recently. I love the watch overall. The finish,feel and detail is very nice on R-T.Just right for me. I had trouble at first. The GMT was dropping 2 hours per day. Time gaining 6 seconds per say (not bad). I sent it back to the jeweler. They swapped in another movement.It’s perfect now. Loses one second per day. Outperforms my Chrono,GMT, ETA-Valjoux 7754. Is the M100 equal or less than the selitta… Read more »

It’s possible my JS Watch Co. 101 has a Soprod C125 … JS Watch reports that it is either an “ETA or a Soprod” and it is definitely not an ETA. It may be an different Soprod model, however.

This Soprod C125 is a great replacement for my Maen 200M diver’s original caliber.

I just put in its successor and again it’s +1sec./day. handcalibrated, like it was last time, when I bought it.

I’m a great supporter of leaving my watches with their original calibers, replacing exactly the same calibers with originals when it’s time and totally worn out.

If it’s based off the ETA 2893-2 you could try 51. https://calibercorner.com/eta-caliber-2893-2/

Is it just me or does this movement look near identical to the new LJP100 from La Joux Perret, which is itself derived from the Miyota 9015 (Citizen owning both LJP and Miyota).
