The Omega caliber 1342 is an in-house vintage quartz movement found in Omega watches from the 1970s into the early 80s. This movement and similar calibers were used before Omega started putting Swatch Group owned ETA movements in their watches.

How to set the Omega 1342:

Think your Omega caliber 1342 powered watch needs repaired because you can’t set the minute hand? Think again! This movement is often mistaken for being broken, when in fact it’s simply an odd watch to set the time on.

Here is a breakdown how to do it:

Set the hour hand: Pull the crown out one click (it only goes out one click anyway!) and rotate the crown clockwise or counterclockwise depending on the time you want to set. Unlike other watches where the hour hand is dependent on the minutes, the 1342 hour hand is independent and jumps hour to hour with each advancement – this also makes it easy to switch time zones when traveling without affecting the minutes and seconds.

Interesting Note: while the hour hand are independent of the minute hand, the minute hand is dependent on the seconds hand as you will see below.

Set the date: Using the method above, you can advance the hour hand forwards and backwards until the date flips to the date you desire to be displayed on your watch.

Set the seconds: The caliber 1342 movement has the ability to “hack”, just not in the way you may be used to with modern watches. To stop the seconds hand on the 1342, do no pull the crown out. Instead, you will push the button in the center of the crown. Yes, that’s a button, not an aftermarket replacement crown!

  • One press of the button will stop the seconds hand for one second.
  • A long press will stop the seconds until you release the button.

Set the minutes: To set the minutes hand on your watch, follow the hacking seconds method above… but this time, press the button on the crown for 5 seconds, then release and press and hold again. You should see the seconds hand start to go rapidly around the dial, with the minutes hand circling as well. When you get the minutes and seconds set to the correct time, release the button!

According to the original instruction manual for the 1342, the correct sequence for resetting the time on a timepiece with the caliber 1342 is as follows:

  1. Set the minute hand first
  2. Set the date and hour hand next
  3. Finally, synchronize the seconds hand

Changing the battery:

The battery for the caliber 1342 was originally a cell number 388, however, those were mercury batteries and are no longer available. You can use a 329 cell. Do not be alarmed when you see that this battery appears to be smaller than the space for the battery, it is smaller but the cell strap will hold it in place. There are spacers available if you want, but shouldn’t be necessary.

There are two screws holding the cell strap down. Carefully unscrew them. It is easier if you wear your finger cots and hold the battery and strap down while removing the screws.

Note: There is an orange insulator tab located under the battery. Make sure you have the insulator film in place before installing the new battery to prevent the battery from shorting.

It appears the battery number 392/384 may also work. It is taller than the 329 (both are 7.9mm diameter, but the 392 is 3.6mm tall VS 3.1mm) so it could cause the cell strap to bend slightly. Do this at your own risk (but leave a comment below if you do!). Below is an example of a 1342 with a 392/384 installed.

Omega Caliber 1342 392 Battery

Battery life:

As mentioned above, the original battery is no longer available for this movement. It’s not clear what the original expected battery life was (Caliber Corner didn’t exist back in the 1970s to document it haha), but using the replacement 392 cell does not yield long lasting power. It may be between 7 months to a year. Please comment below on the battery life you have seen with your 1342 powered Omega.

Markings:

The caliber 1342 found in the watch pictured was signed with:

Ω 1342 / OMEGA / SWISS / SEVEN 7 JEWELS / UNADJUSTED / 4 0 / (serial number)

Does anyone know what the “4 0” means? Please comment below if you know, or if your watch has a different number.

I just rebuilt a Omega caliber 1342. I finally succeeded but it was a very learning lesson. I found that there is a sleeve to install a more available battery. I also found trouble with the date changing mechanism that involves plastic parts. Cleanliness is very important for these to work properly. Also, I found that the magnetized gears that change the date are very touchy so anyone fiddling with that part beware to not try to de-magnetize this watch. It was a fun and challenging project that I won. Cool.

I can. This particular movement first failure is the date changer. It is made of plastic for one thing. Other comment is it is a battery eater. Generally around 1 year service. I removed the date change system to allow this watch to at least keep excellent time. The date change system is too heavy a load for this particular design.

John these are often easily repaired by someone who knows what they are doing. Ruby’s Jewelry in Sunrise FL repaired my watch after other high-end watch makers told me the same thing you were told. Give them a call, and see what happens. Good luck with your watch!

You can fix it, only rotor and electroniscs are not availeble, but a service of the movement is possible. You need a Omega workshop with acces to the parts. If you wan’t, just can send it in to Omega and they do a overhaull for you.

This is a great movement. It is an Omega’s in-house caliber. One of the first Quartz from the brand, if not the first. It is made to last. It has very sophisticated attributes, like the hour hand changing separately, and a second hand that doesn’t backlashes. Extremely precise too. Very interesting caliber.

Just to update you the Calibre 1310 is the first in-house Omega Quartz caliber. Both great movements but cleanliness is paramount for these and they where designed to run on 1.35v mercury batteries, which are no longer available so the equivelant 1.5v batteries will work but with reduced life span.

I believe 1370 is the newer version with exact same functions (push minute setting, quick hour setting, etc.) but uses common 390/389 1.5V battery and longer battery life. 1370s were not made as many as 1342s before they started using ETA quartz movements.

I have an omega seamaster watch with a 1342 movement damaged, so I found an omega 1342 movement working on ebay (don’t know what was the watch model for this movement but not seamaster); my problem us that the watchmaker told me that the movement doesn’t fit and couldn’t be used in my watch.
Is that possible? that the same watch movement model doesn’t fit on a watch that uses that movement?

Not possible. Did he remove it from the dial or is he trying to replace it with the dial and everything? Go to a different watchmaker.

At first he was trying to use the same dial from with everything from the spare movement but it didn’t fit on the seamaster case, then I told him to remove only the movement and replace it for the one in my seamaster watch, he was not able to do it, he said that it did not fit and he did not know why. My problem is that there are not watchmakers in my town with some knowledge on vintage watches. I’ll seek online for some. thanks for your reply.

Hi , I have an omega seamaster quartz 1342 movement. Currently it works fine with reduced battery life as explained above. My question, as this watch has been handed down from father and grandfather is if you encounter problems with the movement (in the future in my case) can you replace the movement with any other? Ie will an ETA movement fit the watch? This watch would be more for sentimental reasons hence the question. Hope someone can answer. Thanks

No ETA movement will fit, this Omega is an inhouse movement. But you can repair it or service it when needed. A good Omega watchmaker workplace can do that. They have to be carefull with the rotor and electronics, because this is a part that is no longer availeble.

i have replaced the 1342 Seamaster movement with an ETA 805.112 the only issue has been the hands. If you get the right hands for the ETA movement, it will work out. Moreover, you will need to adjust the display ,since the two small post do not fit in the ETA movement. I cut them out and fix it the display with double face tape (very thin) to movement center.

I don’t think you can find those exact screws unless you order them from Omega, find them on ebay, or buy a broken watch for parts. You can also just buy a box of random watch screws and see if one fits.

I have a broken 1342. I suspect its the stepper motor. Tried with a spare 1342 but stepper motor also broken on that one… was wondering if I could replace with a current ETA movement, like the 805.112. However, I can’t find the dimensions for the hands. Where can I find it for the 1342? Thanks

Hi Lars, try taking the drive gear out of the stepper motor and demagnetize it. This has worked for me on a few 1342 stepper motors….let it run for a few hours with no load before putting the drive wheels back in. Hope this helps!

Hi thanks for that. That might be beyond my abilities though as I am not an expert watch maker (should have taken on an easier caliber as one of my first projects! ) Stepper motors appear from time to time but are quite expensive hence I’m considering a transplant for a more recent Swiss movement like ETA.

No ETA will fit because this is an Omega inhause movement. The stepper motor are expensive because you can’t buy them new any more. You can send the movement in for overhaull to Omega Switserland.

Hi Lars, I definitely don’t recommend changing the original Omega movement with something else. It will no longer be an Omega, but a franken watch with zero value.
I just serviced my first cal.1342 and I can say I am impressed by the ingenuity and technical solutions used in this old caliber. Because it is so uncommon and weird, many repairable movements are butchered and lost during failed repair attempts. As other mentioned, cleanliness is paramount to have it running.

you can sell them within ebay, but to the step motor not running, I ever check it by microscope, no defect for it, you may just demagnetize it, it is very easy to tear down it.

There is a red plastic pin popping out about half of a milimeter once stem is removed. This red plastic pin also has to be pushed to release the stem. Push this red pin and push and turn the stem carefully back into its resting position at the same time. Release the red pin before you take off the (weak) pressure from the stem.

After trying to find the date of my watch, I’ve determined that the 40 on your caliber and 43 of mine are the first 2 numbers of the serial number of the watch and the numbers below are the rest of the serial number. I could be wrong but both yours and mine corresponds to the years these watches were manufactured, or it’s just a coincidence
