The Sellita SW300 is the main competitor to the ETA 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.

At the time of this post, replacement prices were found for around $280 USD.

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.

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.

The Monta Triumph has this movement. Regulated to chronmeter specs of plus or minus 5 seconds per day.


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