Many thanks for posting this. I do look forward to the next instalment!
The auto click device on Heuer Calibre 12 allows the mainspring, through a train of gears, to be kept from unwinding as the rotor turns to wind it. This is independent of the click on the ratchet wheel which takes the full pressure of the mainspring strength.
The auto click pivots on the calibre 12 automatic winding system are too thin in my opinion and frequently break. They are only 0.09mm. I make the new pivots 0.14mm. Much better. Luckily the pivots go into brass settings rather than jewels so the holes can easily be broached open slightly larger.
A new click costs over £150.00 now from Switzerland, so it is cheaper to repivot the existing one. It is a very difficult piece to hold because of the attached click spring wire, but placing the item in warmed shellac resin eases the difficulty.
Where it fits. The micro rotor sits to the left.
I'm glad that's done !
Now the watch needs a complete service.

+1. Also, what do you use to measure such small tolerances?Originally Posted by MartynJC (UK)
F.T.F.A.
I use a watch jewel held in a stud screw holder. I know the internal hole diameter of the jewel and place the required hole size through the pivot.
Simple and accurate.

Love this stuff!

I helped build a Playmobile Space Shuttle today. A few tricky parts but I managed. Brendan, our skill set is very similar.
Ready for reassembly. Not sure I will have time for further updates.

Your comment comes at the perfect time. Got this tape recorder at the car boots this morning and after recording on it, I'm getting alien signals on the tape. Any advice from the shuttle crew ??I helped build a Playmobile Space Shuttle today. A few tricky parts but I managed. Brendan, our skill set is very similar

They have found a ‘1969 Moonwatch and are looking for a quote to service it. Apparently the other two quotes they’ve had are astronomical.Your comment comes at the perfect time.
