Sellita SW330-1 VS ETA 2893-2:

While the components are not 100% interchangeable, the caliber SW330-1 is essentially a clone of the ETA 2893-2. In fact, these movements are so similar that brands will often use them interchangeably and not disclose which one you are getting beforehand. If the brand lists both calibers and you prefer one over the other, be sure to make the request when ordering your watch new from the manufacturer.

Dimensions, beat rate and power reserve are among the many similarities, but one notable difference is the jewel count. The SW330-1 has 25 jewels and the ETA 2893-1 has 21 jewels.

Here is an image comparing the two movements:

3 Grades and Accuracy:

There are 3 grades of the Sellita SW330-1. The grades and main differences are as follows:

  • Spécial (Elabore) – Nickel balance wheel, adjusted in 4 positions, average rate of +/-5 seconds/day, maximum deviation of 20 seconds/day in all positions, isochronism of +/-15 seconds/day.
  • Prémium (Top) – Glucydur balance wheel, adjusted in 5 positions, average rate of +/-4 seconds/day, maximum deviation of 15 seconds/day in all positions, isochronism of +/-10 seconds/day.
  • Chronomètre (COSC) – Glucydur balance wheel, COSC criteria

To sum it up, the Premium grade will give you better timekeeping and a more refined look than the Special grade. You can learn more about Sellita grading here.

Interesting note: This may not be interpreted correctly, but Sellita seems to mention in the official documentation that when a lot of movements are purchased, only 95% of them must be within the specified limited.

Finishing:

There are two main finishes from the factory: Standard and Refined. There is an option for custom or tailor-made finishing as well.

I just bought the Gevril Wall Street GMT 4953B at an amazing Price. Which makes me wonder if it is a good Watch. It lists for $4195 and I got it for $799 Is it an accurate time piece and is it a true GMT?

I paid the same. You can’t tell it isn’t a Rolex batman unless you look closely and its still a real Swiss GMT automatic. It has a quality movement although not chronometer grade. I would be interested to know what grade of movement was used in these watches. So far so good. This watch has been getting a lot of wrist time. Love it so far.

I have a Farer Charleton with this movement in it. Very accurate so far (less than a second a day). The Farer Maze and Crooms also have this movement.
