Thank you, Anthony! We got the books.

Nothing is more exciting than recieving the new released watchmaking related book.
100+ NO BS (Bull Shit) Watch Tips. We highly promote this practical book for those who are passionate in watches, working with watches, and rookies like us who just entering the watchmaking world. Thank you, Anthony L. We hope someday to see you face to face and hear you share more about watchmaking.

We don't have much to update this week but share our trouble shooting case. The picture shows how we remove the screw with it's head was worn out and stuck in the graver holder.

The graver holder was clamp on the jig borer. We use certering scope to locate the position to drill it through precisely.

In our case, the thread is 3.2mm in diameter, so we use 1.5mm drill to drill it through. The hole is for the later use of reamer to un-screw it.

After drill through the screw, we use centering drill to destroy the head. Don't feed to fast otherwise you may damage the graver holder. Once it's done, you'll see the head become loose.

Now we can easily take the head with rodico. And the final stem is to use the reamer to insert into the hole we drilled before to unscrew it. Ya~~

Finally, that's the right attitude when you work with something complicated. Always keep smiling. Ha...

Pumpkin Season

This has been the exam week for the Pivot Gauge, so we have had a few test exams which have gone up and down for most of us, some pivots have broken, some pivots have died (bend) and been brougt back to life(straigthen back) and some have been good. So we have had all kinds of experience, but hopefully we will pass the real exam.

Last week we also visit the M.A.D Gallery in Geneva. The gallery only appear in Taipei, Geneva and Dubai, so how can we miss it.

Every set-up and prepare process are equally important compare to watchmaking itself.

Last weekend, class 2019 went to visit one of the most famous museum, Patek Philippe Museum.
There are so many amazing watches, clocks, and watchmaking tools. The most amazing things are the bird guns and the caliber 89 pocket watch. It's impossible for mechnical watch enthusiasts to see all the things in one day. If you are  also a watch lover, you must visit this museum.
This week, we are practicing burnishing for the ultimate micro mechanic exam. Burnishing is much harder than we expected. We still need lots practice to meet the goal, perfect black polish. In addition, this week is the last week for Shuai, class 2017. He is soon going back to China for his own workshop. Hence, this week we went hiking and bbq to celebrate his graduation. Wish he all the best for his future watchmaking career.

Practicing and practicing for the pivot gauge exam

This week, we keep practicing turning between centres. Last week we prepared the handle for the pivot gauge, and this week we started to turn the pivot.
 Turning the pivot is the most difficult work compared all work we have learned since we started. The graver has to be sharp all the time to make the cylinder and the shoulder perfect. In addition, good eyesight is more important than ever. When turning the pivot to below 0.10mm, it can be painful to watch and concentrate on this tiny tiny pivot for the whole day.  with the exam date closing in we are all hoping for the best. 
 We also had Pierre with us for his bench test. He is really passionate about watchmaking. We wish to see him come back in a near future.

the moment of realisation when you are told  your making things more complicated than they need to be.

a common issue and a big probelm! re-pivoting is highly skilled, this is the broken one

Winter is coming

The temperature drop rapidly this week in Le Locle, but the schedule in school still make us sweat a lot. We are very glad to have visitor Briana Le from San Fransisco, who is also a member of NYHS (New York Horological Society) and instructor in the west coast. She shared a lot of her visit in Switzerland and encouraged us to maximize our learning while in school. And because of her we also had the honour to skype with America's well known clock maker, David Walter. He showed us some of his amazing works and shared some ideas to us as future watchmakers.
Thanks Briana, and have a safe trip back to the US.

How can we not do selfie with visitor. 

An unforgetable skype meeting with master David. He is really easy going and extremly nice man Also very willing to share his knowledge to us. Thank you.

Thank you Theren, the student of 2017 who donate the very precise and stable base which makes our measurement much more easier.

Sometimes we have to find ways to organize our work.

Very nice black polishing done by Yi-Ting. This is really the ultimate goal to achieve.
This is also our excersise to restore winding stem for a pocket watch.

Another amazing work from Yi-Ting.

Pivot Gauge Handle

We keep moving on to our next challenge this week, making pivot gauge handles. Making the handles from blue steel means this time we have to turn blue steel with HSS graver. Because the hardness of these two material is pretty similar, the graver wear out quickly comparing turn brass or silver steel. We have to spend more time grinding our gravers to keep them sharp for the works.
Turning blue steel also cause some muscle pain, so we also finishing our unfinished tools as a relax exercise.

Happy Birthday, Yi-ting.

Turning blue steel with HSS graver, is not easy but also easy.

Keep fighting with blue steel. 

We'll keep sharing some of our finished tool pictures. Enjoy
