The ETA caliber 2824-2 is perhaps one of the most well-known and most recognized movements in the watch industry. It has been in production since 1982 and was based off of the original Eterna caliber 1427. The “-2” designation indicates that it is the 2nd generation in the evolution of the movement.

The 2824 is considered to be a “workhorse” movement by many watch enthusiasts. There is also a manual wind version of this movement, known as caliber 2804-2.

Four Grades of ETA 2824-2:

There are four grades available with the main differences being how the watches are tested at the factory, the finish, the mainspring, the hairspring, and the anti-shock device used. Let’s compare the grades below:

Standard Grade:
Adjusted in two positions; Nickel plated balance wheel; Nivarox  hairspring; ETACHOC / Novodiac anti-shock device; polyrubies used for pallet jewels.

Elaborated (Elabore) Grade:
Adjusted in three positions; Nickel plated balance wheel; Nivarox  hairspring; ETACHOC / Novodiac anti-shock device; polyrubies used for pallet jewels.

Top Grade:
Adjusted in five positions; Glucydur balance wheel; Anachron hairspring; Incabloc anti-shock device; red rubies used for pallet jewels.

Chronometer Grade:
Adjusted in five positions; COSC specs; Glucydur balance wheel; Anachron hairspring; Incabloc anti-shock device; red rubies used for pallet jewels.

All grades have the same diameter, height, jewel count, frequency, and power reserve.

Accuracy:

The expected accuracy of the ETA caliber 2824-2 depends on the grade.

  • Standard – +/-12 seconds per day up to +/- 30 sec/day
  • Elaborated – +/-7 seconds per day up to +/- 20 sec/day
  • Top – +/-4 seconds per day up to +/- 15 sec/day
  • Chronometer COSC spec

The average for this caliber is the +/12 seconds per day range since most of the 2824-2 movements out in the wild are the Standard grade.

Same Movement, Different Caliber Numbers:

The ETA caliber 2824-2 is supplied to many different watch companies for use in a wide variety of watches. These companies will often put their own branding on the rotor, or make other small changes. This sometimes leads them to creating their own caliber number.

Before the watch industry’s rush to produce and market in-house movements, some watch companies would create their own caliber number to disguise the fact that their watch was using the ETA 2824-2. This isn’t because the 2824-2 was less desirable movement, but rather because much of the watch industry was smoke and mirrors, and also in an effort to create higher prices in the market since nobody knew the cost of the parts within the watches.

Click here for more examples of 2824-2 movements that are branded under different caliber numbers.

Clone Movements:

Since the patent giving exclusive rights to ETA for the design of the 2824-2 expired, there have been similar movements aka “clones” popping up that are based on this movement: For example the Sellita caliber SW200-1, STP1-11, Valanvron VAL-24, Hangzhou caliber 6300, Seagull caliber ST2130.

Replacement Prices:

Although ETA movements are now unavailable for purchase from ETA, you can still find watch parts suppliers offering replacement movements for sale. The gold tone version (see example below) appears to cost less than the silver (nickel plated) version. Prices generally range from $200-$300 USD, but at the time of this post, the gold tone 2824-2 can be purchased for $236.20 USD here, and the nickel plated for $262.42 USD here.

Pros and Cons:

  • Proven reliability in a wide range of watches
  • Easy to regulate
  • Almost all watchmakers have experience with this movement and should have no issues servicing one

Cons:

  • No longer available from ETA in bulk quantities
  • Parts may become more difficult to find as time goes on
  • Expensive to replace

This seems like a question maybe you would know the answer to… If people say the Sellita SW200 is basically the same as an ETA 2824, does that mean some of the parts from a Sellita SW200 movement would work in an ETA 2824? Maybe a dumb question, but I’ve always wondered. Thank you in advance.

Some parts may swap, but not all, as the SW200 was streamlined a bit for easier manufacture.

I spoke to my local watch repair shop (Pt. Hueneme, CA) and was told spare parts for ETA (in general) are readily available. He also told me to stay away from Tudor as overpriced due to movement. He stated Rolex or nothing at all.

Yeah. I’ve seen them reviewed on YT. It’s my understanding that the movement alone costs around $120USD – if you aren’t in the Swatch group or buying them in large quantities, so any piece with this workhorse movement and sapphire on the dial for that price is an absolute bargain.
Enjoy the watch!

They must be giving the movement away to CK… one of the compensations for being part of the SWATCH corporation, I guess. Quite a strange move for CK after years of producing cheap watches with cheap quartz movements. I have seen the YT videos too, but I am left wondering where the wider market for these watches is, they don’t advertise them as if they are targeting those who know what that movement is.

I think – but don’t quote me on this – that ETA are working on an upgrade to the base 2824-2
I remember hearing something about them bridging the gap between the ETA powermatic that runs at 21600bph and has 80hrs by retaining the 28800bph but increasing the power reserve.
If that *is* the case, maybe they wanted to shift some movements without devaluing the Swatch group brands?
