![]() To avoid overloading this article with too many watches, we have a condensed catalogue of some of the best timepieces operated by the ETA 2824-2 movement. With numerous Swiss calibres based on ETA movements, it should come as no surprise that many watches utilise the ETA 2824-4. 10 Best Watches Powered by the ETA 2824-2 The ETA 2824-2 can run for up to 38 hours, while the ETA 2804-2 can last up to 42 hours. The last deviation between these two calibres is the power reserve. Once again, this is due to the automatic winding unit present in the framework of the ETA 2824-2. While the ETA 2804-2 has just 17 jewels, the ETA 2824-2 comes with 25. This is due to the automatic winding mechanism in the ETA 2824-2, which makes it a taller calibre.Īnother difference is the number of jewels holding the movement. For instance, the ETA 2804-2 measures just 3.35mm thick, making it slightly thinner than the ETA 2824-2. ![]() Aside from the type of winding used, there are a few other recognisable differences between the two calibres. Many watch enthusiasts familiar with ETA movements know that the ETA 2824-2 has a manual-winding counterpart known as the ETA 2804-2. It has an accuracy rate of +6/-4 seconds per day. While having the same components and adjustments as the top grade variant, the chronometer-rated ETA 2824-2 showcases precision and reliability that meets the standards of the Official Swiss Chronometer Testing Institute (COSC). The last version is the chronometer-rated ETA 2824-2. Adjusted in five positions, the top grade ETA 2824-2 displays an accuracy rate of +/- 4 seconds to +/- 15 seconds per day. ![]() The top-grade variant uses an Anachron hairspring, a Glucydur balance spring, an Incabloc anti-shock device, and red ruby pallet jewels. The elaborated ETA 2824-2, on the other hand, uses the same components as the standard grade but has been adjusted in three positions instead, giving it a precision rate of +/- 7 seconds to +/- 20 seconds per day.įollowing the elaborated edition is the top grade ETA 2824-2. The standard ETA 2824-2 has an accuracy rate of +/- 12 seconds to +/- 30 seconds per day. Starting off with the most ubiquitous of the bunch, the standard ETA 2824-2 has been adjusted in two positions and comes with a Nivarox hairspring, a nickel-plated balance wheel, a Novodiac anti-shock system, and poly-ruby pallet jewels. Like many other ETA movements, the ETA 2824-2 comes in a variety of grades: standard, elaborated, top, and chronometer. Accompanied by its 25 jewels, the Novodiac anti-shock system also helps in reducing the wear and tear the movement undergoes. While the ETA 2824-2 is a self-winding calibre, it also features manual winding and hacking capabilities. Ensuring each component stays in place is the Novodiac anti-shock system. Once fully wound, this ETA movement can last for approximately 38 hours. The ETA 2824-2 is also equipped with a ball-bearing rotor that winds bidirectionally to energise its power reserve. With its Etachron regulator, the ETA 2824-2 produces a beat frequency of 28,800 vibrations per hour (4Hz). Depending on the watchmaker, the date window can be positioned at different locations on the dial. It provides central hours, minutes, and seconds functions, along with a date complication. The ETA 2824-2 measures 25.6mm in diameter and has a thickness of 4.6mm. Some of the most recognised ETA 2824-2 clones include the Sellita SW200-1, the Seagull Calibre ST2130, and the Valanvron VAL-24. However, due to the expiration of its design patent back in the early 2000s, a number of other manufacturers have also begun creating “clones” of the ETA 2824-2. ETA has been producing the ETA 2824-2 since 1982. It is an automatic Swiss-made movement based on the Eterna Calibre 1427. The “-2” designation on the movement signifies that it is the 2nd generation ETA 2824 calibre. The ETA 2824-2 is probably one of the most well-known ETA calibres in the entire watch industry. Stick around as we discover more about the ETA 2824-2 calibre, what it can do, and some of the best watches that use it. This ETA calibre is a go-to watch movement for numerous watch brands due to its durability, preciseness, and cost-effective qualities. There are only a handful of calibres that have proven themselves worthy of the title “workhorse” - one of which is the ETA 2824-2 movement. If you have been around the watch community for some time now looking around blogs and forums, you have probably come across the term “workhorse movement.” Although not the flashiest of calibres, a workhorse movement is a simple tried-and-tested watch calibre known for being reliable, affordable, and easy to service.
