STP caliber STP1-11 is a Swiss made automatic watch movement with 26 jewels. Similar to the Sellita SW200-1, the STP1-11 movement is an ETA 2824-2 clone.

Official technical documentation dates the STP1-11 as being produced as far back as November 1, 2012, although this movement was being researched and developed as far back as 2008. Modifications were made to tech sheets as recently as May 2, 2020.

Swiss Technology Production Caliber Stp1 11

Fossil Affiliation:

STP stands for Swiss Technology Production, however, you will mostly see this manufacturer simply referred to as STP. Their website also references the name SwissTP. Whatever you call it, STP is a Swiss factory owned by Fossil Group with a production rate of about 100,000 movements per year.

STP1-11 VS STP1-11M:

There is also a similar caliber STP1-11M which is the non automatic version of the STP1-11. The manual wind version is slightly shorter at 3.7mm but has the same case fitting diameter of 25.6mm. The beat rate is the same, as well as the power reserve, but the jewel count drops from 26 to 20 without the need of an automatic wind unit.

Accuracy:

The STP tech sheets claim an accuracy rating of -0/+15 seconds per day, operating within a max amplitude of 320 degrees and minimum amplitude of 200 degrees. Each movement is tested in 5 positions, which is comparable to the ETA 2824-2 Top grade.

No Date:

We couldn’t find an official version of the STP1-11 without a calendar complication, but found a watch brand that had STP modify the STP1-11 for a no-date watch. so it is possible:

“The movement is modified to a no-date movement, all components related to the date have been removed. Upon request STP has adjusted the movements that there are only 2 crown positions, one for winding and one to set the time.” –Méraud Bonaire

Crown Functions:

As this movement is based on the ETA 2824-2, the crown functions in a similar way:

  • Position 1 – Manual-winding mode: Depending on the watch, this could mean the crown is pressed against the case, or on a watch with a screw down crown, it means the crown is unscrewed and in hand-winding mode. When in hand or manual winding mode, turning the crown forward (clockwise) will wind the mainspring. Rotating in reverse will ratchet the movement.
  • Position 2 – Date setting mode: With the crown pulled out one click, the calendar or date setting function is engaged. Rotating the crown forward (clockwise) with advance the datewheel forward. In this mode, rotating the crown counterclockwise will do nothing.
  • Position 3 – Time setting mode: Pulling the crown out two clicks engages time setting mode. Rotating the crown towards you (counterclockwise/backward) will advance the hour and minute hands. Rotating the crown away from you (clockwise) will move the time backward. The seconds hand will be stopped for fine tuned time setting (this is what is known as a hacking seconds hand).

Are you more of a visual learner? Watch this video we created to show the crown functions on the STP1-11.

Replacement Prices:

While we do not have volume pricing available at this time (still need to obtain a price list), replacement prices for individual STP1-11 movements were found online in the range of $159.00 to $190.00 USD.

Pros and Cons:

Pros

  • Based on the familiar ETA 2824-2, so most watchmakers will be willing to service a watch with this movement.
  • Based on a workhorse movement that powers a majority of the Swiss made watches in the world.
  • Available from the manufacturer without supply threats.
  • Finished and tested to be comparable to “Top” grade ETA.

Cons

  • Individual cost is roughly the same as an original ETA 2824-2.
  • STP parts do not seem to be readily available by the major watch parts suppliers.

Quick STP1-11 FAQS:

Can you over wind this movement?
No.

Does it hack?
Yes.

Is it COSC?
SwissTP tests them to COSC criteria (ex: 5 positions), but only COSC if the watch brand had it officially certified.

Are parts interchangeable with ETA or other clones?
Some may be, but not all.

Can I replace my 2824-2 or SW200-1 with this?
You should be able to, that’s the advantage of ETA clones. The dimensions are the same.

This is the internet, there is information here, more information than you could ever imagine, all you have to do is search for it so if you search for what makes a Swiss movement or watch Swiss, then you’ll find the answer you’re looking for and you’ll save yourself from looking like a tool in the process. It’s a win win…

This is not a Chinese Movement assembled in Switzerland. This is a proper Swiss movement made in Switzerland. There is confusion between the Fossil owned STP (Swiss technology production) and the similarly named SwissTech who ARE from Hong Kong and DO assemble in Switzerland.

I’ve actually found the original movement for the skeletonized STP6-15, and that originated from China. Why would this be different?
Nevertheless the movements are quite OK, look and work pretty good

It depends. STP-11 comes in a Chronometer version that is COSC certified. This means that the components of the entire watch are manufactured and assembled in Switzerland, while most “Swiss Made” watches, while manufactured in Switzerland, need only have 51 percent of its parts manufactured there.

I think COSC doesn’t mean the watch has to be entirely made in Switzerland, just Swiss Made and following what you said about 51%. Almost no watches are 100% made in Switzerland. Read the COSC page on this site, I think it explains well.

I thought that means winding of the crown is clockwise. If it’s based on ETA 2824 then the winding weight should wind in both directions. I have seen ETA clones only wind in one direction though.

The only ETA Clone that I know of which winds, by that I take it you mean the AUTO ROTOR mechanism, in one direction is the ETA /VALJOUX 7750/ SELLITA SW500 series a ALL othe ETA and SELLITA Clones are dual directional

The movement is like every other ETA or ETA clone movement, in order to wind the movement by hand, you have to turn the crown clockwise. The rotor however, is bidirectional, it winds the movement regardless of the direction of spin.

There are some new micro-brands that are using this movement. I own a echo/neutra AVERAU with STP 3-13 that is an improvement of STP 1-11 model. The watch looks very nice with it.
In addition to 1-11 version, it has the swan neck regulator and blue screws.

I own a Formex Essence Leggera with a STP1-11 Movement for about 8 weeks now and I can admit, that this movement is incredibly accurate. I have +1.5 secs per day and when I lay the watch on the side, with the crown upwards for a night (after 2 days), the watch runs exactly on second, compared to a radio-controlled digital watch. In my opinion the movement is top notch, even better than a sellita… Read more »

It is an adjusted SELLITA SW200 If it has 25 jewels it would be a ETA2824 Most movements of either number can be, with patience, adjusted to near chron-standards by a competent watchmaker The cost is in the time it takes to do the adjustment and can take, I’m told, an hour or two which would work out at around £100-12 I’ve got a couople of watches to hand one with the ETA2824 and the… Read more »

The (Mass)Drop Felix automatic watch uses the STP1-11 for its standard model and an elabore-grade SW-200 for the upgraded one. Sadly, neither variant of the Felix has a date window despite both movements providing said complication.

So they removed the automatic winder and sell it as a mechanical manual wind instead of just using a manual wind movement in the first place? Seems odd. I would be interested to know more about why they did that.

Rob is right that the brand Serica is selling watches with the STP1-11 as mechanical manual winding. Maybe they came across a cheap batch of movements and wanted to have a manual wind so just used them without the rotor. Like why not just use the Unitas 6497 or 6498? Strange.

Sounds like you had a “Friday Afternoon” movement. The wobble sounds like reversing wheel problem, which I have had on an ETA and a Sellita which is easily fixed but the balance as well sounds pretty unlucky
