Team B
Origin: Japan/Switzerland & Canada
Name: Tetsu & Dean
Watchmaking class: Fullskill
Current mood:
This week, (05~09 December) Dean & Tetsu continued their current task, pivot gauges.The difference here is that they were finally ready to face a practice exam, which was a simulation of a real one.
The results showed where they were and what to be improved.There will be a few more practices coming before the real one, but those will be for the next year.Next week will be the last school week of this year, so the guys do not want any stress before Christmas.They will just be producing mandatory pivot gauges; as many pieces as possible to reach the required number will be enough for now.One more week to go!
We wish you all a nice weekend!
Dean & Tetsu
Team C
Origin: Switzerland, Norway & USA
Name: Renato, David, Francesco, Åsmund & Robert
Watchmaking class: Fullskill
Current mood:
This week David and I went deep into hairspring work. First we practiced removing and mounting the hairspring on the collet and staff including centering of the collet and vibrating it for a used balance. Then we started completing brand new sets of balance parts. Cutting and shaping the inner coil, attaching to the collet, adjusting the orientation, mounting on the staff, vibrating it to determine the outer pinning point and from there calculating the second inner pinning, i.e. how much to cut on the inside coil. Afterwards repeat same as before. This we'll do for four balances. Very interesting work that needs a lot of care and attention to many details. Quite exciting!

This was a week of working on various movements, and some faults introduced to them for our benefit of troubleshooting.
The interesting part of working on these movements is the various solutions that are built into them. For instance, the retaining feature of the stem that is used to wind/set the time of a watch:
- The ETA 6498 movement uses a threaded fastener on each side of the movement to retain the winding stem and its associated parts, requiring access to both sides of the movement for assembly/disassembly of that system.
- The ETA 2824 and ETA 2846 movements secure the winding stem and it's associated parts with just 1 screw, needing access to only 1 side of the movement for assembly/disassembly of that system.
It is little features like this that make the history and development of watches interesting.
Local news here in Le Locle: We have snow!
-Robert
Team D
Origin: Finland
Name: Xinying
Watchmaking class: Technician
Current mood:
This week was pretty busy because I took two practice exams. I made couple small mistakes that are easy to correct and I feel that I am ready to take the real exam next week. Also continued gear train practices and had a lesson about lubrication. Feeling that time goes by really quickly because after next week we will have a christmas break already.

HENRIK's WORDS:

Asmund, Francesco and Robert continued to complete as much of the gear train and barrel exercises as possible before the break! and Miguel, Daniel and David had trial filing exams and also the real filing exam! Renato and David L. practiced vibrating the balance and hairsprings to the corect frequency! Both Tetsu and Dean have almost finished all their mandatory pivot gauges and had one trial exam! Very nice week ending with some snow!! Have a great weekend everyone!
