A French company (SilMach) backed by Timex Group is claiming to have opened a new chapter in watchmaking with the creation of a silicon motor that matches the accuracy of quartz-based movements with the elegance of a mechanical watch’s sweeping hands.
I wonder how long the battery lasts. However, some big watches with conventional mechanisms use standard small movements with lots of free space (I could extend the battery life by sticking 4 more SR626SW cells there) so a larger battery could be an option.
It says the battery lasts 10 years before you have to replace it.
But I preferred my watches (I’ve gone smartwatch, now) to have the self winding as you walk mechanism inside. If you had more than one they made moving display cases that would keep them wound if you didn’t want to bother with setting the time again after a few days of not wearing it, plus those always seemed way cooler than needing a battery.
