Theren, Tomas and Simone started their final exam this Friday with the oral and theoretical and will continue the practical part throughout next week. Wish them all the best of luck!

Meanwhile Shuai and Eddie moved to workshop 2 and are continuing to work on their school watches and various repairs.

Last week before Finals!

Movements for Henrik to check

It is the last week for three of our student until the big day...Finals.
Theren, Tomas, and Simone have been practicing hard on their school movements, which have to be perfectly serviced to Henrik's standards (which is not too easy).
They will start with the theory exam next Friday, so wish them luck!

Tomas polishing a caseback for practice
Besides the usual work, Henrik has taught the last lesson KHWCC has to offer, and that would be case polishng.  Case polishing may not be a watchmaker's job per say anymore, but to make a complete watchmaker the students should have some experience with all aspects of the SAV.

Shuai and Eddie on the other hand will be moving to the second class room next week to allow the test takers maximum focus for the finals.  While in the class room they will continue to work on their school watches.  Eddie has made a couple of prototype wheels while Shuai has been working on a detent escape wheel.

Just Encase

Shuai checking the trueness of the crown

Tomas setting hands
This week the students learned how to do the finishing touches to a touch aside from the movement.  First they were taught how to correctly shorten a winding stem from brand new stems, which are usually excessively long.  Once shortened and the crown fitted, they must true the crown to the stem and the watch.
Simone making the hands aligned

Learning how the pressure testing machine works

Next the students moved on to hand setting, specifically, the setting of the hands for quartz calendar watches, quartz chronograph, and mechanical chronographs.  Hand setting is extremely important because it is what the customer sees.  Bad hand setting results in tardiness or wrong date readings.
Once these steps have been accomplished, encasing is to be done.  In encasing, cleanliness is a must.  No dust or grease may remain on the dial, dial indexes, hands, or crystal.  One technique doesn't work for eveything, therefore many different styles were taught to our students.

On Thursday, Bergeon came to the school to showcase their new products.  There were some interesting products that came in the perfect time for the encasing lessons, such as the black mats, sticky tipped sticks, cleaning cloths, and micro fiber cloths.  Bergeon even gave the school many samples to try out!

running out of time

Tomas burnishing his escape wheel
This week we had a taster course scheduled for Dr. Tao, a Chinese molecular biologist working currently in Denmark.  He fell into watchmaking from reading online blogs and quickly built interest into this beautiful profession.  Through the 5 day taster course, he learned what watchmakers actually did and got a taste of what skill sets a watchmaker requires.
A bit larger than molecular biology

This is the last week Simone, Tomas, and Theren will be working on their school watches during the school hours since they will have to start preparing for their finals in mid March.  Tomas assembled his tourbillon and made adjustments and added small details to his complication, such as the banking pins and studding up of the hairspring.  Simone did final adjustments to his chronograph mechanism and started to do final finishing of the components.  Theren started assembling his main movement, also making adjustments to endshakes and the escapement.

Eddie started making wheels and pinions to test out his design.  Shuai continues to design his school watch, starting to prepare the making of the mainplate.

A Necessary Evil

Theren and Tomas machining out their school watch
Throughout the week the students continue to work on their school watches.  Shuai and Eddie have started on their designs, Eddie has even started to make some prototype parts such as the barrel cover and drum.  Shuai has been taking down measurements and designing his watch, still undecided on some specifics of the movement.
Tomas begun production of his pallet fork and milled out the spokes for his tourbillon.  Theren finished his balance bridge and pallet fork bridge and is focusing on the completion of the main movement now.  Simone finished all the finishing on his school watch and will start to assemble and adjust the chronograph next week.
The Witschi Q1 is extremely powerful

Theren trying out quartz analysis

Although the school is focused on classical watchmaking, quartz is still something the students will need to know for their future careers in watchmaking.  The students learned how the quartz watches work and how to analyze them for the different types of errors that may occur in the quartz and what they can do about it.  By using the Witschi Analyzer Q1 we are able to see very detailed information about the workings of the quartz watch.  In the end, quartz watches are also very interesting and have their own appeals.

The Breguet template with the Breguet terminal curve

Theren trying out bending of the Breguet

Eddie giving the Breguet a try
This week the students learned how to bend the long awaited Breguet Overcoil.  The Phillips Terminal Curve and Breguet Overcoil is used to overcome the Caspari effect, which is one characteristic that affects isochronism.  It is considered a higher skill to be able to bend an overcoil since it is not so easy and it affects time keeping greatly.

Shuai turning the chronograph seconds hand tube
Besides learning about the Breguet hairsprings the students continued to work on their seperate projects.  Shuai finished the restoration of a Valjoux 72 and is now working on a second one.  This time he had to make a new chronograph seconds hand tube.  Eddie continued on the design of his school watch while finishing some timing exercises at the same time.  Theren made some bridges for his jumping second mechanism and is now starting to make the pallet fork bridge and balance bridge.  Simone tested out different types of finishing in preparation of decorating his school watch mainplate.  He has tried circular graining and côtes de Genève and will continue to test in the following week.  Tomas made the fixed fourth wheel for his tourbillion and is getting ready to make the pallet fork next week.

School watches and Restoration

The students kept working on their individual projects this week.  Eddie continued to design his school watch this week, almost finishing his Inventor drawing.  He has been reading a lot of books for research on different ways of designing the movement.  Shuai is working on a client's Valjoux 72 chronograph, doing restoration work including polishing down a chipped jewel on the pallet fork.  Tomas is making incredible progress on his tourbillion, making the tourbillion cage spin today.  Simone finished adjusting the main movement for his school watch and has started beveling and decorating the mainplate and bridges.  Theren worked on the winding and setting of his school watch all week, finishing the ratchet, crown, and winding pinion.

Next week the students will learn the theory behind the Breguet haisrping and how to bend them.  Everyone is looking forward to it!
