      I can tell you with a 100% certainty, I only get 35 hrs for the power reserve. This movement has been known to have issues with the power reserve. My watch is close to specs so for now I am not going to do anything.

        Good luck Stan. They state it averages about a 40-42 hour power reserve.

        Cal. C125 is a modular automatic movement with a GMT function. Built on the Soprod A10-2 base (now known as M100), this movement differs from other GMT movements in that the “local” time (quick-set hours) is the 24 hour hand rather than the standard 12 hour hand. The date is similarly “tied” to the regular timekeeping hands, and pulls the GMT time along with it. This is due to the fact that the module uses the day mechanism rather than a unique gear train.

        The GMT module increases the movement thickness from 3.6 mm to 4.1 mm and the stem height from 1.5 mm to 2.0 mm. Interestingly, Hager claims that this movement is 5.67 mm thick, uses Novodiac rather than Incabloc, and has 40 hours power reserve.

        Formerly known as Calibre SOP 9384/A10-2, the movement was renamed Cal. C125 in 2016 when Soprod renamed the A10-2 to M100.

        Cal. C125 is used by Oak & Oscar and Hager.

        Seiko Instruments first designed their 4L25 to create an ETA 2892A2 competitor for the Swiss OEM market. Soprod announced their Swiss Made version, Cal. A-10, in 2004 and began offering it to Swiss watch makers. The company was not explicit about the design source of the movement. In 2007, Soprod was acquired by Peace Mark of Hong Kong for the company’s quartz movement operations in China, and the Swiss mechanical operations were sold to Festina Group the following year. Seiko introduced their own 4L25-powered Brightz and Credor models and Soprod continued to produce the A-10 and later the A10-2. The A10-2 was renamed Soprod M100 in 2016.

        Oak & Oscar

        Oak and Oscar is owned by Chase Fancher and launched their first watch in 2015. It features a Soprod movement and foreign case assembled and tested in the U.S. by Lum-Tec. The strap is made in the U.S. out of Horween leather.

        The American watch brand scene just gained a new addition with Chicago-based Oak & Oscar. The brand is entering the market with a watch called the Burnham, a limited-edition piece that packs a lot of detailing into a straightforward design. Oak & Oscar looks and sounds like something straight out of a hipster’s how-to handbook, with references to bourbon and crafted-leather accessories, but there is some real substance here in the execution.

        Inside the Burnham beats a Soprod A10 automatic movement. It’s the new Swiss workhorse and while it may not be the sexiest movement in the world, Oak & Oscar has applied some perlage to the bridges and star-shaped cutouts on the rotor to add visual appeal. The case is 42 mm, and the lugs are designed with a curvature to ensure effortless wear. The watch is tested, assembled, and finished by the folks at Lum-Tec over in Ohio, so you can expect a high level of build quality.

        Soprod SA was founded in 1966 in Tramelan, Switzerland as a mechanical watch component producer. The company was purchased by Léman Capital in 2005 and combined with quartz movement producer SFT Group to become STM Holding. This was purchased by Hong Kong-based Peace Mark in 2007 but financial issues forced the sale of the Swiss mechanical movement operations to Festina in 2008.

        Today, Soprod is owned by Festina Group. Unlike competitors, Soprod prides themselves on in-house components and designs, though their premier movement uses Seiko technology. The company has manufacturing capabilities in Tramelan, Sion, Le Saignelégier, Maiche, Le Sentier, and Porrentruy.

        Soprod primarily focuses on watch movements and complications. They are best known for the Alternance 10 (now called M100) and complicated C series movements in the A10 family.

        "Flesh could not keep its glamour, nor eyes their sheen. They would go to nothing soon. But monsters are forever"

        “America will never be destroyed from the outside. If we falter and lose our freedoms, it will be because we destroyed ourselves.
        If destruction be our lot, we must ourselves be its author and finisher.
        As a nation of freemen, we must live through all time, or die by suicide".
        Abraham Lincoln
