The caliber F03.111 is part of ETA’s Trendline line-up. ETA claims that a 20mAh battery will last 34 months and a 28mAh battery will last 48 months in this movement. Replacement prices were found at around $26.95 at the time of this post.

From Tick Talk:

“The movement above is the ETA F03.111. It has 3 Jewels and lots of plastic, including complete wheels and pivots in the gear train (it’s what I would expect from a low end Seiko or a Timex). Don’t get me wrong. Plastic isn’t bad but it evokes poor quality and the rest of the movement follows. I would never service one of these movements, it would simply get replaced.”

“…The F03.111 is a part of ETA’s Trendline which they describe as “economical movements for mass produced watches.” In contrast ETA’s Flatline watches which include the movement is described as “flat, reliable, numerous functions, high performances.” Which would you rather have in your watch?”

My wife has this movement in her TAG watch. I spent $20 to get the battery replaced and now I learn that the movement itself costs about that much. WTF!?

I’m so happy I stumbled onto this website. The insides of a watch always felt like a mystery. “This watch has a great movement”. How can I know this is true. But as I compare watches and find that a luxury watch might have the same movement as my more lesser quality watch, I can make a more knowledgeable decision as to how much more value will the brand name provide for my daily usage

I have this movement inside my Tissot PR100 which was discounted to 185 GBP.
As such a 25 GBP movement fits well into the type of watch (its hardly a TCQ Grand Seiko !).
I’d be far unhappier if I’d bought a TAG ladies Aquaracer at 10x the price to find it boasted the same movement.
That said, and maybe I’m lucky, but its keeping excellent time to well within 2 sec per month.
