Watches and cars

 Starting this week strong. Our professor, Michael along with his student, Bernd returned from Andermatt. Michael lead a week-long interactive horology program in The Chedi, for members of the Bentley Mulliner drive experience. Michael’s program involved a variety of basic watchmaking skills as well as some history of horology and motor sports. A presentation was given on the relationship between Bentley and Breitling, discussing the uses of chronographs in the world of cars.

Bernd, serving as Michael’s assistant, demonstrated the process of hand turning with a watchmakers lathe to make winding stems. Showing the amount of work need to make a simple part by hand.

Back to Le Locle, the students are keeping busy. Craig is making progress on his school watch. Using the lathe to make the base plate for his calibre. It is shaping up to quite a beauty.

Cesar (myself) is prototyping some dial possibilities with brass. A task much harder than expected, for every process a jig needs to be made, and for every jig another jig has to be made. But we’re making progress.


Prototyping 

As for the new students, they are now learning to operate one of the many machines in our school, the drilling machine. Chris has also been having some fun with the school new 3D printer and made himself a screwdriver holder. 


Myself again, update from last week. This week I finished the restoration of a Bergeon pallet fork tool. Not a quick job.

Kept the steel blue 

That’s it for this week. Thank you for reading and until next time.

Artemy bids your a good weekend

Summertime

 Week 24

The warm weather of summer has arrived! Long pants are exchanged for shorts and workshop windows are flung open.

 This week, the school welcomes another new student: Gary from Canada. He is starting the 2-year Fullskill course and already has many ambitious plans.


STUDENT HIGHLIGHTS

Workshop A

Students:
    Art, Bernd, Cesar, Joan, Louis Lu, Mun, Nine

    Art and Nine continue their progress in the technician course, working on aligning the pallet jewels in the escapement to achieve the minimum locking that is still fully safe.

Art is nearly complete with the work; preparing now for the Escapement exam.
 
Cesar also spent this week working in the field of pallet alignment, but rather than the pallets themselves he repaired  the tool used to measure and depth the jewels.

Workshop B

Students:
    Craig, Christiaan, Gary, Philippe, Sense

    
This week Christiaan, Gary, and Philippe learned how to use the profile projector to take very accurate measurements of work pieces.

Christiaan has a look at the image displayed on the projector

Craig also began work on adjusting pallet fork jewels, but found time to practice polishing the 0.1mm bevels for his watch dial.
Clean and sharp, even under magnification


Thank you for reading!

Hope to see you again next week!

New era

 This week at KHWCC, two new students started their full-skills programme. They joined at a good week since on Wednesday the school took a trip to Geneva to visit the EPHJ fair. 

Our two new students 




Saw a bunch new technologies for manufacturing and measuring. Got a chance to have some hands on experience with the latest watchmaking tools and see tools which are not yet out.

Our professor Henrik constructed a gear train model based on a vintage 30mm calibre in Fusion360 to 3D print. This is used as a teaching material to let students better understand the inner workings in a watch.


Voila

That’s it’s for this week. Thank you for reading!

Until next time.
