Watchmaker

Week 14

This week the school is proud to congratulate Ivan Berets on the manufacture of his school watch. It is a rectangular movement based on the Peseux 7001, featuring a German Silver mainplate and three-quarter plate. Beveling and finishing all completed by hand. Beautifully done!

This week also held the yearly watch festival in Gevena, with multiple showcases of watchmaking including Watches and Wonders, AHCI, and Time to Watches. The students took a day to peruse the wide variety of clocks and watches from independent and small-studio watchmakers, talking shop with some of the designers and perhaps gaining inspiration of their own.

STUDENT HIGHLIGHTS

Workshop A

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

    Bernd, Cesar, Joan, and Louis Lu began learning how to harden and temper steel. A tricky process to get the right temperature and time while avoiding warping.

 

Workshop B

Students:
    Craig, Ivan, Louis, Sheikh, Varun

    

Louis made a balance staff for his school watch, and notably out of titanium. Strong and light, and also more difficult to machine.

Thank you for reading!

Hope to see you again next week!

Last week!

 Spring weather is truly upon us. 

This week Art and Nine are making progress in their technician course, Art took his gear train test this week and is moving on to the escapement.

The senior students are making progress on their school watches and out most senior, Dunny, had his last week with us. 

Louis finished making the wheels and assembling his gear train.

Using the topping tool

Louis used a vintage topping tool to reduce the diameter of his center wheel to make a smoother transition of power to the third wheel.

Craig is working on his dial and devised a method to cut post for the dial feet by making his own cutter.

And…. Voila

This is Dunny’s final week with us before he travels back home to Texas to go independent. We all wish him the best of luck with his future endeavours.

Until next time Dunny

That’s it’s for now.

Thank you for reading!

Until next time.

Spring Machining

 

 

Week 12

This week held the first day of Spring. So the cold weather is gone... I think. At least for now. Maybe.

Craig surprised everyone with fresh-made desserts: three large pans of strawberry rhubarb crumble and pear rhubarb crumble. The occasion? The ingredients were on sale and he wanted to have some dessert. Hey, no one's complaining. 

 

STUDENT HIGHLIGHTS

Workshop A

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

    Bernd completed three watchmaking tools this week: a pointed nose vise, a balance wheel support, and a polishing tripod.

From plan to product

Workshop B

Students:
    Craig, Dunham, Ivan, Louis, Sheikh, Varun

    Craig continued his sprint through the technician course by passing his Gear Train exam, which covered everything from barrel endshake to wheel truing to winding and setting lubrication. Next up is the heart of watchmaking theory: the escapement.

 

Louis made more progress on his school watch, milling and finishing the two rollers for his escapement. This included shaping and fitting the jewels for proper function.

Hope to see you again next week!

Snow’s back

 Here in Le Locle the spring will have to wait a bit. The warm weather is gone and the snow is back.

This week Sabri paid us a visit, showing us he’s stock of new and vintage watchmaking tools. 

Everyone looking for treasure 

The Athenian watchmaker Anastasios Sousounis gifted us an interesting book about the long history of Greek invention. Anastasios was a student who took part in the school’s summer hairspring course. We thank him for his gift, it will be added to the school’s library. 

Ivan made a specialised collet to fit in ratchet wheels, for finishing. Very useful little gadget. 

Finished product 

Putting it to use.

The student Cesar started playing around with Geneva strips and using mild enamel fillings. The surfaces need more finishing before the stripes are made but we’re getting there.

This week Craig perfected using the pantograph for engraving. Doing five passes with the pantograph not running using a special bit he made with Agathon.

That’s it for now, thank you for reading!

Until next time 

Dreams of spring

 Hello again, the last patches of snow are melting and the days are warm. The newer students are becoming more familiar with the machines and finishing techniques while the senior students are labouring away on their own projects and school watches. 

Louis is making progress on school watch. This week finishing the plates, pillars and pinions for the gear train. He’s using German silver for the base plate and bridges, a difficult material to turn.

Craig is experimenting with dials for his school watch. This week he tried out the new batch of black nickel plating on this dial.

Cesar is playing around with different finishings on his tools. This week he attempted some circular Geneva strips using the milling machine and a rotating table.

That’s it for this week. 

Until next time.

Getting Technical

 

Week 9

STUDENT HIGHLIGHTS

Workshop A

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

    Art and Nine have begun the first section of their Technician course, moving from micromechanics and fabrication to ensuring the proper operation of an assembled watch. For the past few weeks, they have been learning how to clean and oil Incabloc jewel settings, assemble and lubricate the winding and setting mechanism, correct wheel flatness, and adjust the endshake and sideshake of the gear train.

Workshop B

Students:
    Craig, Dunham, Ivan, Louis, Sheikh, Varun

    Craig also started the technician course, swiftly completing all the work up through the lubrication and mechanical adjustment of the mainspring barrel.

 

Craig has also been working on his own dial design, experimenting with steel press-fit into brass.

 

Initial proof-of-concept

 

Milling out a template for greater alignment accuracy

 

This week, Louis explored using the pantograph as an easier way to create gear wheels, rapidly milling out eight blanks and cutting teeth into four of them.

 

Thank you for reading!

Hope to see you again next week!

Visitors

 Hello again,

Another eventful week at K&H. Early in the week our first visitor was the watchmaker and entrepreneur Roman Winiger from Open Movements. He gave our students a detailed explanation of his goals and journey so far. Open Movements is a non profit organisation that aims to construct watch movements and parts for the public domain using open source principles. It is a place where watchmakers can freely share ideas and help one another.

Later in the week, the alumni Charles came to the workshop. Charles is first generation K&H student, a real OG. 

The gang 

Finally, the new batch of students have started a new chapter. They have all started using the 8mm lathe and learning to hand turn. Will soon be pumping out winding stems pivot gauges.

Let’s not forget the peppernuts brought in by Craig

That’s it for now, until next time!
