If you have been a watch enthusiast for a while now, you will know that many watches use the ETA 2824-2. 10 Great Watches with the ETA 2824-2 Movement For the most part, each clone movement produces a comparable performance and precision rate as the ETA 2824-2. Other examples of ETA 2824-2 clone calibers include the Seagull ST21, the Hangzhou 6300, the STP-11, and the Valanvron VAL-24. Operationally, the ETA 2824-2 and Sellita SW200 produce similar accuracy rates, even with their varying grades. While the ETA 2824-2 contains twenty-five jewels, the Sellita SW200 has twenty-six. The main differences between these two movements can be seen from the design of their rotors and the number of jewels they each have. This does not mean, however, that the ETA 2824-2 and Sellita SW200 are completely the same. In fact, both the Sellita SW200 and the ETA 2824-2 are quite similar in appearance. Since Sellita used to work hand-in-hand with ETA in the 1980s, it knows its way around ETA movements. The Sellita SW200, one of the most recognized clones, is considered by many as the main rival movement to the ETA 2824-2. As a result, some other watch manufacturers have created their own versions of the caliber. In 2003, ETA’s rights to the design of the 2824-2 caliber reached their expiration date. This caliber is less thick and features seventeen jewels and a 42-hour power reserve. However, they feature precision and reliability that match the criteria of the Official Swiss Chronometer Testing Institute (COSC).Ī manual-winding version of the ETA 2824-2 also exists, known as the ETA 2804-2. Finally, chronometer-level variants of the ETA 2824-2 also contain the same components of the top-grade versions. These upgrades allow the top grade ETA 2824-2 caliber to produce an accuracy rating of +/- 4 seconds to +/- 15 seconds a day. Moving on, a top-grade ETA 2824-2 movement is adjusted in five positions and uses a Glucydur balance wheel, an Anachron hairspring, and an Incabloc anti-shock device with red rubies for its pallet jewels. The elaborated model uses the same components as the standard ETA 2824-2, but is adjusted in three positions and has an improved accuracy rating of +/- 7 seconds to +/- 20 seconds per day. This standard ETA 2824-2 variant has a precision rate of +/- 12 seconds to +/- 30 seconds per day. The standard variant has adjustments in two positions and uses an anti-magnetic nickel-plated balance wheel, a Nivarox hairspring, and a Novodiac anti-shock system with 25 polyruby jewels. Like most ETA calibers, the ETA 2824-2 comes in different grades: Standard, Elaborated, Top, and Chronometer. The movement’s Novodiac or Incabloc anti-shock system, which each consists of 25 jewels, helps keep every component of the ETA 2824-2 in place while also reducing wear and tear. Although this caliber is self-winding, it also possesses manual-winding and hacking seconds capabilities. As a result, when fully wound, the ETA 2824-2 can stay powered for up to 38 hours. This Swiss caliber also uses a ball-bearing rotor which rotates bidirectionally and produces more energy for its power reserve. It also has a date complication that can be located on varying areas of the dial, depending on where the window cutout is.Įquipped with an Etachron regulator, the ETA 2824-2 movement has a beat frequency of 28,800 vibrations per hour (4Hz). This ETA 2824-2 provides a watch with its central hours, minutes, and seconds functions. It has fairly standard dimensions, with a diameter of 25.6mm and a thickness of 4.6mm. Released in 1982, the ETA 2824-2 is a second-generation Swiss automatic movement based on Eterna’s 1427 Caliber. If your interest is piqued, we have also curated a list of some of the best watches that use an ETA 2824-2 movement. Join us in learning more about the ETA 2824-2 and what it has to offer. Known by the watchmaking community as an absolute workhorse, the ETA 2824-2 is an exceptional caliber that, if regulated correctly, can keep time just as well as the ETA 2892 movement. There are numerous ETA calibers to talk about, but for this article, we will be focusing on the popular ETA 2824-2. They are durable, reliable, and easy to produce, making them ideal for mass production. ETA calibers are some of the most ubiquitous movements in all of the watchmaking industry.
