Perhaps this little red star is taken for granted by many of us? You see it every time you visit the forum.
A 'virtual' version of it appears, in a tiny, animated form, spinning above the menu options on the "Member Area" screen of this website.
It is a scale representation of an actual watch component. What is it? What does it do? What watches do we find it in?
Richard
We find it in Perpeutal calendar watches nt.
Also Minute Reapeating watches. nt.
It's name: Minute Transmission Wheel. nt.
What it does: It is part of the minute-counting >
and switching system. It is transmitting information about the position of minute hand to the minute snail.
ok now that the question is answered,
i think you have to post an image of your watch that it is used in richard...
show us the PPC please

Here's mine, if that helps.
My favorite IWC, except for all the others.
Bill
awesome
thanks bill.
is this the quintessential IWC watch?
No. Not found in a Perpetual Calendar.
In Minute Repeater: Minute Transmission Wheel...
Yes. Isobars, was too quick to respond - initially stating this component was found in the "Perpetual Calendar". In fact, this is a critical component in the "Minute Repeater" - just as he later posted.
I am no expert here - and don't have a Minute Repeater - just trying to spark some discussion. I would normally let this thread run its course for at least a day before jumping in - but since there was some confusion around the "Perpetual Calendar" - I did not want us to get off track.
Forgive my 'layman' explanation. I don't guarantee this is 100% accurate - but that is why I posted this - perhaps there are others with more subjective expertise.
The Minute Transmission Wheel helps "figure out" how many minutes to chime. As you know, the minute repeater chimes the hours, quarter-hours, and minutes. The Minute Transmission Wheel "tells" the minute snail how far to go - and helps stop the "minute snail rack" which counts the chimes. You can see this wheel outlined in the "Portuguese Minute Repeater Skeleton" here.
Additionally, there is a link to a YouTube video of this watch - where you can see the "minute snail rack" - which is a large component - swinging down under the bridges when the minutes are being chimed.
wow that is cool.
i've never seen a minute repeater in the flesh so that's the first i have seen the mechanism work
thanks for this richard
Hi Richard...I see this part in diagram images for
Perpetual Calendar movements too. The best explaination of how the Minute Transmission Wheel operates I found was in the [i]GrandComplication[i] book.
Your video is awsome!
Hope you and your family had a great Thanksgiving Richard!

Best from Isobars.
Please tell us more....
If this is used in a Perpetual Calendar module - please share more. I am not aware of it's use there - at least not in any IWC Perpetual movements. What manufacture's movements use it?
This is also a good view of the Minute Repeater...
I like this computer model of the Minute Repeater module....
Keep in mind that this is not an entire movement here - this is just the layer of components for the "Minute Repeater" mechanism.
My goof Richard, I was going very fast before >
and confused it in the assembly of the Grande Complication.
Sorry for the confusion.
