The Glycine caliber GL224 is a Swiss made automatic watch movement. As of 2016, Glycine Watch SA is owned by Invicta Watch Group.

ETA or Sellita Base:

The early Glycine caliber GL224 movement was based on the ETA caliber 2824-2. There may still be some of the ETA pieces out in the wild, but most of the newer GL224 powered watches available are based on the Sellita SW 200-1.

Glycine Caliber Gl224 2824 2

The movement pictured above is an earlier caliber GL 224 based on the ETA caliber 2824-2 with a custom branded Glycine rotor. This example was found in a pre-Invicta F104 watch.

Pictured below is an example of a GL224 based on a Sellita caliber SW200-1 with a custom rotor. The image was submitted by Brad (from the comment section of this post) of the movement found in his Glycine Combat watch.

Glycine Caliber Gl224 Sw200 1

How do I know which movement is in my watch?

Throughout the official Glycine documentation and technical data, they only refer to the caliber GL224 as a Swiss automatic movement. ETA and Sellita both engrave their logo and caliber number below the balance wheel, however, the easiest way to tell if your Glycine watch has the ETA or Sellita is by the jewel count on the rotor. If your GL224 powered watch has the ETA 2824-2, it will say 25 jewels. If your watch has the Sellita caliber SW200-1, the jewel count will be 26.

Why are they the same caliber number?

Glycine is currently owned by Invicta watch Group, which has been known to change base calibers in their watches while maintaining the same caliber number. Even though the SW200-1 is a clone of the 2824-2, they are not the same movement. For that reason, it would be beneficial to the watch community if they identified the movements with different caliber numbers, or at least added an indicator such as GL224-2. Since the GL224 can be either an ETA or Sellita, you might not know which you are getting, especially from sellers that don’t show the back of the watch.

GL 224 or GL224?

The official Glycine documentation refers to this caliber as GL224 without a space, but as you can see in the ETA powered movement at the top of this post, the rotor is engraved: Cal. No GL 224, with a space. The Sellita based image submitted by Brad is engraved: Cal. No GL224, without a space.

It’s possible that Glycine got rid of the space when they switched from the 2824-2 to the SW200-1, but this is doubtful because datasheets of older models powered by the 2824-2 were written the same way (GL224), despite the rotor having GL 224. Glycine provides limited documentation and images on their official website. If you have a 25 jewels ETA based GL224, please comment below if the caliber number on your rotor has a space or not.

Examples of watches with this movement:

Below is an ETA 2824-2 based GL224 movement found in a pre-Invicta Glycine F-104.

The base is the Sallita SW200. Most people call it the clone ETA. The obvious tell is 26 Jewels on SW200 and 25 Jewels on ETA

The rotor indicates 25 jewel not 26. I’m sure Glycine will need to switch to the SW200 as it’s base given Swatch Groups shift away from reselling ETA outside of their brands

To be clear, the rotor says 26 jewels.
The movement is a SW 200. My Glycine is using Sallita movements in the combat sub editions.

There is actually a one-year injunction against the Swatch group for forcing other companies to put the 2824 movement inside their watches and the number of other things are going on with the Swatch group and shoving in the 2824 movement inside watches like jaulinna Jean which they own among 50 and other brands such as army gun Hamilton and Tissot and many more. the Swatch group also pulled all parts and I’ll repair is… Read more »

Its a standard 2824, with the Glycine mods doing nothing to improve or affect the over quality and movement provided by the ETA.

The specs don’t say elabored. It says the finish, is elaborated. Meaning they’re not using the standard rotor and plate. Apples and oranges my friend.

I’m not a watchmaker so I can’t open and compare the movements to win this argument. So I’ll just leave it at this: I’ve never seen ‘finish elaborated’ used to describe decorated rotor and plate. I think they mean the elabore grade and there is a bit of a language inaccuracy in their description. Cheers!

I just bought a Combat Classic GL0121 with a GL224 movement. It looks the about the same, but the rotor clearly says 26 jewels. I think that it may be a SW200 movement.

I have just found the makers mark on the edge of the movement above the balance wheel. My GL224 has a sw200-1 movement.

There’s nothing inherently wrong with the SW200-1, but if you are using a different ebauche it should be a different Caliber No. to differentiate. The two movements are not the same, even if it is a clone.

Brand new watch, only holding about 2 hours of power reserve before stopping. F104 model 48 mm size. Tested it fully wound in different positions and with it on the wrist all day. This could be why Glycine is giving all of their watches to grey market sellers at 75% off. There’s possibly something wrong with Glycine watches, don’t let the low prices full you. AVOID.

I’ve been wearing the wTch now for over a month or so. It’s accuracy improved! Measured it 3 times since and the diversion measured in 12 hours is 0 seconds. It diversion in 14 days was 4 seconds. It beats my chronometer by far! Most accurate timepiece I own.

Last week I received a Combat 6, 36mm expecting the ETA 2824 to find that the jewel count was noted to be 26 and eventually identified the SW 200-1 stamp on perimeter of movement. I’d have to say I wasn’t entirely surprised given what I have read about the SW family and it’s umbilical relationship with ETA. So, I set (hacked) the time as of about 15:00 on Thursday Jan 18th and strapped it on.… Read more »

If the 18.4 seconds you measured is in a 24 hour period, this could probably be reduced significantly through an adjustment by a watchmaker.

My jeweler and watch repair specialist advised me the same thing about my Glycine Combat 6 Model GL0115 w/caliber GL280 26 jewels.
He said that 26 jewels is in fact a Sellita SW200 base movement. My watch day/date has stopped and needs repair. The warranty is still good and cost me little to ship to Utah where the service center for Glycine is.

Bought the Incursore on MassDrop. It’s the 26 Jewel variety. Set it 5 days ago and been wearing daily since then. Ran +3 sec in the first 24 hours and had held at +3 sec total every time I’ve checked it in 5 days and 6 hours. We’ll see if it lasts, but seems I got lucky given the variability on this one.

Fingers crossed.

Since I had my UTS 2824 regulated (after 6 years of hard use), it runs much better. I bought a Glycine combat sub 0087 (2824) and time holds well. Regarding pros/cons of getting a watch regulated, if it starts losing at least five minutes a week (my situation), the watch should be looked at.

Have a pre-Invicta Double Twelve with this 26 jewel movement, which after reading above comments, I understand is the SW200. After about three days, zero deviation (during this period, it varied plus and minus about one second). Sure, it’s been only a few days, but I’m very impressed. Purchased it from Jomashop for a total of only $505.

After my last adjustment almost 4 weeks ago, my Glycine Combat Sub has virtually zero deviation. During the daytime ( I wear my watch for approx 12 hrs/day) it gains about a second but when I put it away for the night crown up, it’s pretty much spot on with the atomic clock the next morning.

i’ve got the combat sub, which does not have a see-thru back nor any reference to jewel count. it’s new so i’m guessing it’s after they switched to the sellita-based version. but is there any other way to know? or is my assumption, which is very likely correct, the best available?

by the way, it is extremely accurate and smooth. great background on the movement.
