Will your Aquaracer break? A shocking scientific study on the calibre 5

neowatch

Hi Albert, sorry to hear that your cal5 had developed a fault. Did your watchmaker have any idea why it failed. Do you always leave it on the watch winder when you are not using it

I’m not sure if all mechanical connected cal5 and cal16 heads use Selita or a mix of Selita and ETA. I guess there is no way of telling unless the back is opened. Maybe if any connected users with a mechanical head who have opened the back for some reason can comment here then we can answer this.

Thanks! 👍 But I’m more happy now with an ETA movement inside the Calibre 5 module 😀

My watchmaker told me that there was nothing broken, that the Sellita just needed a service… but considering the price to service it (and still having the same Sellita), I decided to go for a new ETA movement instead

I always leave it in the watchwinder when I’m not using it, but some weeks ago, even setting the watchwinder to maximum speed, the Sellita was stopping after 4 or 5 days, so I also had to manually wind it in addition. Suddenly one day, even after turning the crown 40 times, the watch did not start…


To know what is inside the Calibre 5 module we need to remove the caseback, for sure 😉

But we can directly see what is inside the Calibre 16 module 😀

It was not easy to spot, but I found the ETA logo here 👍:

And also the '7750’ stamp:

The Calibre 16 by Sellita would have the Sellita logo and 'SW500’ instead.

It was a nice surprise 😀, because being a watch from 2018, I was afraid it would have a Sellita movement due to restrictions on sales of ETA movements to brands outside the Swatch group

Because it goes flat on the winder?

The only correct way to manually wind a calibro cinco is to shake it like its hot. What most people refer to as doing the "Seiko shake"
