The Sellita SW300-1 is a slim automatic watch movement, Swiss made with 25 jewels. This is the main competitor to the ETA caliber 2892. Many reputable watch companies are using this movement as an alternative to the ETA mechanism due to it being more economical and readily available.

You may have seen this movement written as the SW-300 but according to Sellita, the correct way to spell this caliber number is SW300 without a hyphen between SW and 300.

SW300 Family:

The SW300-1 is the base caliber of the SW300 family. There are two other variations in this family of movements:

SW200-1 VS SW300-1:

While the SW200-1 and SW300-1 share many similarities, they are not the same. The biggest difference between the two, as pointed out in the Sellita catalog, is that the SW300-1 is a 1mm slimmer movement. The SW300-1 is 3.6mm thick and the SW200-1 is 4.6mm thick. This makes the SW300-1 a preferred choice for thinner models such as higher end dress watches.

Replacement Prices:

At the time of this post, replacement prices were found online for around $280.00 USD.

The current Glycine Airman 18 GMT lists this as the movement in its watch.
I’m pleased with it!

This caliber is used by Montblanc watch company as a base for its caliber mb24.09. So it is used in TimeWalker Automatic series, e.x. models 110337, 110340, 112532 etc.

What are the “grade” differences in the SW300? I’ve recently ordered a Lundis-Bleus Ref 1200.

Does anybody know how many turns of crown fully wind the mainspring?
I have Glycine Airman Base 22 Purist with this movement. Beautifull ticking 😉

Hello I love your website and I thank you for it. Can you help me with one thing regarding the SW300 movement? What is the winding direction of the rotor? Does it wind both ways like my Seikos? I’m asking because I want to put my new watch on a watch winder. Thank you in advance!

I have this in my IWC portofino, the ticking is louder than the ticking of my hamilton eta 2824-2. The date jumps reliably at 6 minutes before 12 whereas my hamilton jumps reliably at 2 minutes before 12.My IWC runs at 3+ seconds per day. I can recommend it but beware of the louder ticking. I did not hear it but my girlfriend noticed immediately
