The ETA caliber 2834-2 is a Swiss made automatic movement with a day-date complication. The calendar display on this movement is similar to the Rolex President Day-Date, with a full day of the week indicator at 12:00 and a date at 3:00 [also possible at 6:00 depending on the dial design].
The 2834-2 is part of ETA’s Mecaline collection. Official documentation was found dated as far back as 2009, with updates as recently as 2018.
2834-2 VS 2836-2:
There is also a similar caliber 2836-2. The main difference here is that the 2836-2 features an inner day of the week calendar wheel, placing the day indicator left of the date at 3:00 on the dial [with abbreviated spelling]. The 2834-2 being discussed here has an outer day wheel, placing a panoramic style day of the week indicator at 12:00 [with the full spelling].
Because of the different calendar display, the 2834-2 has a larger overall diameter of 29mm [13”’], compared to the regular 28XX size of 25.6mm [11.5”’]. For this reason, the 2834-2 and 2836-2 are not interchangeable and cannot be directly swapped.
Setting the 2834-2:
- Position 0 – Crown in hand-winding position [running position]. This can be against the watch case in watches without a screw-down crown, or in unscrewed position on watches with a screw-down crown.
- Position 1 [one click] – Quickset adjustment of the day and date. Turning the crown clockwise will advance the date. Turning the crown counterclockwise will advance the day of the week.
- Position 2 [two clicks] – Time setting position with hacking seconds.
Note: To avoid damaging the movement, do not attempt to set the date when the hands are between the hours of 9pm and 3am.
Power Reserve:
According to ETA, it takes a minimum of 27 winds of the crown to fully wind the movement. The watch community seems to agree on 30-40 turns being sufficient to reach full power reserve. In contrast, when depending primarily on the rotor [oscillating weight] to wind the movement, it can take up to 1,250 turns or 1 hour and 30 minutes of the movement in motion.
Although the power reserve of the 2824-2 based movements, including this 2824-2, is widely known to be around 38 hours [for example, as listed in ETA tech sheets dated 2018], the official ETA website claims this caliber has a “typical power reserve” of 42 hours [as of 2021]. Please comment below as to the power reserve you have experienced with your 2834-2 powered timepieces.

Replacement Prices:
As with most ETA movements, although the 2834-2 is unavailable from ETA, replacement movements and parts can still be found online.
Examples of watches with this movement:
Below is an example of an ETA 2834-2 found in this Tudor Prince day/date watch. Notice that instead of Incabloc or Novodiac for the anti-shock device, Tudor [Rolex] used a Kif shock absorber [as they did with all of their other movements at the time as well, before switching everything over to paraflex].
