The ETA caliber 2893-X family is part of the Mecaline Specialities line of ETA movements. The 2893 is an automatic movement that is Swiss made with 21 jewels. It is a modular movement that uses the 2892-A2 as a base, but with the addition of a GMT complication. There are three variations of this movement described below.

2893-X Variations:

The 2893 family of movements is available in 3 variations: 2893-1, 2893-2, and 2893-3. The most common of the three is the 2893-2.

All three versions are the same diameter, same jewel count, and the same beat rate. The main differences between these calibers are as follows:

  • -1 has a world time GMT disc and a quickset date
  • -2 has a centrally located GMT hand and quickset date at 3:00
  • -3 has a world time GMT disc and no date

The world time disc on the -1 and -3 features indicators for the different time zones around the globe. Interestingly, despite ETA showing the world time disc as being larger on the -3 without a date, the parts lists calls for the same part number (2520/1) in either the -1 or -3 movements. ETA refers to this GMT disc or 24 hour disc feature as a universal hour mechanism.

Above is part #2520/1 for the universal hour mechanism on the 2893-1 and 2893-3. ETA shows the wheel with the time zone markers, but many brands use a wheel with 24 hour markers instead.

Excellent post. I had no idea the 2893 has a world timer option. Now to hunt one down!

Right behind you as long as I can find one with a custom look. I don’t want anything wth the standard wheel ETA included with the movement.

What I don’t like about the ones with the time zones is the wheel is so big and obvious that when it’s used by different brands it starts to feel like the same watch. Like if Longines uses it and some other brand uses it they look too much the same.
