The Landeron caliber Landeron24 (L24 or just 24) is a clone of the ETA 2824-2 workhorse movement.

You may recognize the name Landeron as a maker of vintage chronograph watch movements. The name is the same, but as of 2018, Landeron movements are produced by Depa Swiss Movements Company (DEPA LUXURY DISTRIBUTION GmbH), with a workshop located about an hour away from Le Landeron, Switzerland.

In Depa’s own words:

Landeron24 Swiss Made movement same as ETA2824 even small quantity for your projects” –source (1/8/19)

And also this:

“It will be very difficult for many small and medium watch brands to produce Swiss Made mechanical watches because they will not be able to access mechanical movements, even if Sellita will not have enough of the parts supplied by ETA for the SW200 and other calibres, also because many they will turn to them by creating delays for up to 18 months and substantial price increases are not ruled out. We from Depa Swiss Movements can cover a very small part of the market but we are studying the possibility of expanding our production, we will supply our products to everyone. Follow us on Facebook” –source

Depa has two lines of watch movements: Premium and Economy. The Premium family of movements are 100% Swiss made with a Swiss made certificate. The Economy series is said to be Swiss made with “Far East made parts”, which is the watch industry’s way of saying the parts are made in China, assembled in Switzerland, and also include a Swiss made certificate.

On the ETA 2824-2 clones page, a longtime community member said this about the Landeron24:

“I would also add the Landeron 24 (nee DEPA Swiss), which like the Valanron VAL-24, uses Sea-Gull 2130 ebauches and then adds 51% Swiss value.” –source

Further confirmation that the parts in fact come from Seagull is still needed. If so, this is what we here at Caliber Corner have coined as a “Switzerland via China” movement.

Depa has also advertised a caliber 24H with a modified hour hand to display 24 hours instead of 12.

A watchmaker who worked there said he set all the pieces at -1+3s/d.
Parts from China? Most of them.
Swap parts with SW? Yes.

Remember that Cartier and IWC (Richemont) run sellita… You pay as gold an ETA copy…

Hi, I usually check for your replacement cost section but this hasn’t any info. Does anyone know how much one piece of L24 movement is? And what are their minimum requirements? I’m curious to test one.
