The ETA caliber 955.112 is part of ETA’s Normflatline family of quartz watch movements. The 955.112 has 7 jewels with a gold tone finish and a blue circuit board. It is a “V8” movement, indicating that it is assembled in Switzerland.

Official technical documentation for this caliber was found as far back as December 19, 2005, with updates as recently as December 10, 2019.

Update 11/2023: The cal. 955.112 is no longer being offered and is no longer listed on ETA’s official site.

ETA 955.112 VS 955.412:

There is a similar caliber 955.412 which is smaller in diameter than the 955.112:

  • 955.112 = 11.5”’ (25.6mm diameter)
  • 955.412 = 10.5”’ (23.3mm diameter)

Interestingly, these two calibers shared the same tech sheets at one point, and also contain some interchangeable parts. This is also confirmed on the packaging of some new old stock ETA parts (source), seen in the image below:

Changing the Battery:

The ETA 955.112 is equipped with an end of battery life indicator aka E.O.L. This means that when the battery is low on power, the seconds hand will jump every two seconds, indicating that you should make arrangements to get the battery replaced.

The battery cell number is 371 (or 395), depending on the watch. The diameter of these two cells is the same (9.5mm), but the height is different (2.6mm for the 395 vs 2.1mm for the 371). Some watches (particularly ones using the slimmer battery) may include a battery cell spacer as seen in the picture below.

ETA 955.112 Tag Heuer Kirium

When putting the spacer back, the tabs on the edge of the spacer go downward (around the battery) and the points go upward.

It is also very important to note the black insulator tab under the battery tab. Make sure this is in good condition (without battery acid corrosion present) and in place under the battery when installing the new cell.

Examples of watches with this movement:

The image at the top of this page is a 955.112 found in a TAG Heuer Aquaracer.

The pics below are two different examples of 955.112 movements found in Tag Heuer Kirium watches. Both are stamped with ETA 955.112, but looking at the metal shield around the coil, TAG signed them with “TAG HEUER 3.89” and “TAG HEUER 4.0” respectively. If you have more insight as to the meaning of these numbers, or if your watch has a different number, please share in the comments below…

Caliber Commentary:

According to a post by The Sydney Tarts:

“ETA 955.112 is a very common quartz movement found in gents’ watches. It is also one of the most reliable quartz movements you can get on the market today. The movement is easily replaceable, and a quick glance through the interwebs will net you one of these movements for about 25 bucks. So don’t worry if your watch dies on you. Just drop a new movement in and you have a brand new watch again!” –Source

Replacement Prices:

The calibre 955.112 has been discontinued and is no longer offered for sale by ETA, but there are still watch parts suppliers with stock available. Prices were found online in the range of $39.33 USD to $61.95 USD.

Other brands using the 955.112:

Since ETA is part of the Swatch Group which supplies its own watch brands with ETA movements, you may find this caliber listed with a different number depending on the brand. For example:

  • Bulova (2562, 2631.10, 2802.10, 2806.10, 2962, 6182.37)
  • Certina (caliebrs 115, 119, 260, 753-1)
  • Longines (caliber 115.2)
  • Mido (caliber 115)
  • Tissot (calibers 3232, 3239, 3332, 3542)

Just wonder how many months this caliber (ETA 955.112) runs. I guess it depends, among other things, on the complications (without or without day of month, moon phase, etc.). Someone with a Tissot PR 100 chronograph (showing week day, month, day) mentioned approx 18 months. On ETA’s web site, with 40mAh, the theoretical runtime is rated 78 months – quite a different story…

23 years now, since 1998 it’s running in my Tag Heuer Kirkum.What a great little movement. For my mechanical dive watch I had to pay 6 times a complete overhaul in approx the same time.
The 955 is running like new.

Found in various earlier Belair Seapearl divers such as A9701 and A9705 (titanium) models. a later A9701 Seapearl includes a Ronda 715 instead — a clear step down for cost savings in an established model for them.

This is reassuring, as I have just bought an Aquaracer WAY111 and worried it was a clone as the movement did not say Tag!! turns out its ERA – but wonder if is SHOULD say Tag on it???

I have one in my Certina DS First 200m Diver. There is a little “bounce” in the third quadrant of the seconds hand, but it’s consistent after a year and I stole it on Ashford.com’s clearance section for less than $120 so it’s an ok compromise. I don’t mind a quartz movement. As a matter of fact quartz is king, both in terms of reliability and durability. Of course there’s nothing meets the mojo quotient like a nice organic automatic or manual, but keep an open mind. The workmanship on this watch is on par with Ball, Hamilton, Seiko Presage,… Read more »

1994 I had the chance to get a Camel Trophy Limited and special Edition Swiss Team, built up with this specific movement! I still wear it. Out of today’s oversized exotic mechanicals or multi connected Smartwatches or just buy and trash later wrist watches, I love this discrete but special (to me) watch. Classy size and time keeping meets sporty Swiss Made! See the PLUS!
