STP caliber STP1-11 is a Swiss made automatic watch movement with 26 jewels. 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.


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.

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

How Swiss is this really? Like Swiss Swiss or China Swiss?

My Zodiac super sea wolf saturation uses this and I love it.


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…

Great Movement with a tough shock absorption and a power reserve of 40 hours, tested. Winding however is in both direction… or clockwise only as listed ? Not sure

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 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.


This is also in the Maen Hudson


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.
