The POWERMATIC 80.111 (23 Jewels) has plastic components incorporated into the movement - hence the need for only 23 jewels. BTW, are you a watchmaker or a watch tinkler? I suspect it is the latter and not the former.Īs for use of plastic components in the Powermatic 80. Plus, it has been discussed previously by one of the forum's watchmakers that lowering the beat rate does not provide much substantial lengthening of the power reserve, but it is the lengthening of the mainspring that provides a substantial increase to a movement's power reserve. Tudor has shown with their Calibre MT5602 one can have a movement with approx 70 hrs at beat at 4hz. If you want the 'full spa treatment' of a watch's movement made by the Swatch Group, then you are looking at Longines, Omega and their other higher-end watches.Ĭlick to expand.Where do you get off in telling someone they are wrong! But bear in mind, this is a common industrial practice with other mainstream brands in a similar price stream as Tissot, Hamilton, Mido and Certina. In other words, I see a jerkiness of the second hand with both movements.Īs for the Swatch Group Service Center swapping out a movement that needs to be repaired for a retrofitted movement, it is probably correct.

For me, when comparing the movement of the second hand between a watch with an H-10 (Hz) movement or an Oris 733 movement (4 Hz), it is hard to differentiate when viewing with the naked eye.

If anything, the slowing down of the beat rate in the C07.X11 movements was to prolong the maintenance service cycle by reducing the wear-and-tear/friction of the movement itself.Īs for the jerkiness of the second hand between the 3 Hz compared to the 4 Hz movements. It was the lengthening of the mainspring and the addition of silicon components-particularly in the escapement-that increases a watch's power reserve and not slowing down its beat rate. Click to expand.I may not have direct experience with the Powermatic 80, but I do have experience with the H-10 movement as both are built on the C07.X11 platform.Ī common fallacy is a notion the beat rate was slowed down from 4 Hz to 3 Hz to increase the power reserve.
