Moo!

WEEK 5:

Harman Wadhwa 
Origin : New Delhi, India
Age : 28
Watchmaking class : 8 month Service & Technician course
Current mood : this week, I started oiling and assembling of mechanisms, learning and understanding the type of oils which are used and at which sections. A regularly well oiled & serviced watch, it can run for over 100 years. 😮 
Not an easy peasy week: the movement's click spring and incablocs are hard to deal with..!! Thanks God It's Friday!!

Pierre Aubert
Origin : Toulouse, France
Age : 22
Watchmaking class : 2Y Fullskill Program
Current mood : "Just got introduced to the mother of machines: the Jig Borer..! What does it do? It drills holes to the micron. It's insanely accurate. Without its aid, many of today's production machines could not even be made. It also played a key role in the establishment of the metre as a measuring unit. In fact, the Société Genévoise d'Instruments de Physique (SIP) built the first jig boring machine (1921) to provide the International Bureau with viable copies of the Mètre des Archives (standard for the Metre). Previous copies were only metal bars of 1m length with no subdivision..!! Work options offered by these models were thus very limited..!!*
 Haha sorry I got a bit overboard 😆. But what a fascinating machine!! I've really enjoyed using it, and only look forward to using it more in the future..!! 
I have also started to make 10:1 cardboard samples for my own design of the setting mechanism. I look forward to getting ahead with it throughout the week-end and hopefully start making it soon!! Stay tuned for more pictures :)!"

PS: *Jig Boring by Robert  S.Connell is a brilliant book should you want to explore the history of Jig Boring 😉!!


STEP 1:
 HARMAN & OILING 









Incablocs: 
Shock absorber to protect the delicate balance pivots (of only 0.07mm diameter!). Why is it important? Because the balance wheel is what a pendulum is to a clock: a regulating organ. Without it, no accurate timekeeping!

                                Incablocs: Not enough oil has left me with a kidney shape..!!                            Incablocs: good minimum portion of oil and shape!! Bingo
STEP 2: 
HARMAN - CLEANING WATCH PARTS


  Parts are in for a bath!! 🌊😜 


STEP 3: MAKING NEW FRIENDS!!





                                                  STEP 4: PIERRE - JIG BORING!!

It is key to have a very detailed plan before machining..!! A good plan helps to create the right routine, which will most importantly ensure consistent and accurate operations!! It helps you to respect the machine. You can't beat it. You're only its steward- you need to understand its own language should you wish to achieve precise work! 




  STEP 5: PIERRE - Cardboard Assisted Design

10:1 Drawing of my setting mechanism

 10:1 Cardboard Model 
I am making cardboard samples of my setting mechanism.This will allow me to easily determine if it is functional or not! 


 HENRIK's WORDS
Its getting more intensive as expected deeper into the program, Harman progressing very well with his assembly, cleaning and lubrication skills, next week he will try out servicing and repairing the barrel with mainspring (energy accumulator) of a mechanical watch. Pierre is progressing well with the Fullskill program, just got introduced to the jig borer, he seemed amazed by it and will continue to practice on it next week. I have nothing new from my side to report back except my custom project, a watch with sapphire case is progressing as expected, will show pictures of it when finishing more of it.

Milling machine, Screwdrivers and Tweezers.


WEEK 5:

Harman Wadhwa 
Origin : New Delhi, India
Age : 28
Watchmaking class : 8 month Service & Technician course
Current mood : "First week of technician course, introduction to all the bridges, gear trains and their respective function in the watch mechanism. Important lesson learned: never touch watchmaker screwdrivers and tweezers, they have a soul. A lot of effort goes into proper filling of the tools.
Also practiced dissembling & assembling of movements: ETA 6498 & PESEUX 7001, it's good fun." N.B: Be careful while removing the yoke spring, it might jump out and get stuck in your beard. :P

Pierre Aubert
Origin : Toulouse, France
Age : 22
Watchmaking class : 2Y Fullskill Program
Current mood : "Bridges for my school watch were reasonably easy to design, but designing a new yoke and setting lever spring is quite an adventure!! And a great deal of fun of course!!! I've also had the opportunity to explore the milling machine (Aciera F1): such a fascinating machine!!! It's interesting to note that skills are not at the center of milling operations. In fact, discipline and careful planning are of the essence here to ensure accurate milling..!! I am looking forward to spending more time on it in the upcoming week. Time flies by and I am just amazed by how much there is to learn in watchmaking: I find it reassuring to know that one lifetime won't suffice to even explore 0.1% of it..! Haha ok I'll stop here- see you next week for more watchmaking adventures."  

STEP 1: GETTING THE RIGHT TOOLS
 We had the pleasure to welcome Guillaume Böttger from Bergeon. It is quite nice to see that tools are specifically catered to the watchmakers' needs. In fact, the latter are continually discussed and reviewed by Bergeon to facilitate everyday watchmaking operations. 

STEP 2: 
HARMAN- 6498 ASSEMBLY AND TOOL MAINTENANCE




STEP 3: 
PIERRE - INTRO TO THE ACIERA F1/MILLING OPERATIONS


 Ensuring the flatness accross all the table surface. 


STEP 4:
AFTER SCHOOL HOURS - REDESIGNING THE WINDING SYSTEM

  Used a profile projector to draw the current 6498 winding system. This gave me a good idea of how much space was available for my own design. Next step: CAD (Cardboard Assisted Drawing..! I need to make a 10:1 cardboard sample of my own design to determine if it will work! Stay tuned :)! PS: I have decided to make the spring and yoke spring into one common part. 

HENRIK's WORDS
This week was a diverse one, Pierre started with the Aciera F1 manual watchmakers milling machine, learning to set it up and make his first cuts with it, he also work with his school watch designing the winding and setting mechanism. Harman started with his watch service and repair course module of the technician course, the first things he did was to practice sharpening screwdrivers and tweezers as well as practicing using them on a small and large movement, surprisingly less parts were lost and the ones lost were found, its important to learn the skill of finding lost parts too! I have been super busy myself with the course but also with a side project; I experimented with designing and modifying vintage pocket watch hands for the future school watches to give students ideas, below, some pictures of the case dial and hands, I also received my sapphire case for a custom project I have been working on for some time now, I am very happy with the final product, super clear and perfectly polished! Thank you Bernice at Hong Kong Bright Sapphire Co.,Ltd for the great business and easy communication!

School watch design experiment.


Sapphire case for custom project arrived  this week, made by Hong Kong Bright Sapphire Co., Ltd.

NEVER GIVE UP...!!!

WEEK 4: 
NEVER GIVE UP...!!!

Harman Wadhwa 
Origin : New Delhi, India
Age : 28
Watchmaking class : 8 month Service & Technician course
Current mood : "The micro-mechanics are over for me! Very thrilled to start technician work next week!!"

Pierre Aubert
Origin : Toulouse, France
Age : 22
Watchmaking class : 2Y Fullskill Program
Current mood : "I think I have learned a thing or two about patience this week 😝: I had to re-start from scratch my balance bridge support 9 times..!!-before it actually met the desired quality :)) Looking all good now haha. See you next week!"

STEP 1: 
LEARNING TAPPING (INTERNAL THREADING) & EXTERNAL THREADING
 


STEP 2: HARMAN's SHIFT => SERVING JUGAAD 😁

Before

After

STEP 3:
 "Striving for perfection and trying to catch excellence..!" 
(Just trying haha it's a long journey😝)

Before

After
Only finishing left to do


 STEP 4: 
Vintage hands for school watch before modding/modernization


Modified shape of vintage hands, scraping finish with applied red super luminova, with polished sinks, matt top surface and beveled and straight grained back-end of boss
Jig boring circular table with scraping for precision flatness, not decoration. This is where I got the idea for the hand surface finish with randomly scraped spots



HENRIK's WORDS

One month gone! Time warps in le Locle for sure, already next week Harman will begin his manipulation course for the technician course. This week was interesting as we tried out drilling, thread making and tapping of brass in the lathe, we also got to use the tailstock microscope (centering microscope) in the Schaublin 70 lathe, this was not an easy task for the students at this stage, but we will review it on a later stage in the course again. I started to experiment with a school watch as I have a bunch of old vintage hands that are suitable for the ETA 6498 movement, the hands I had in stock had no real shape or finish to them as can be seen in the before pic, as I did no want to have the same painted, black polished or brushed hands as is so common anyway, I tried instead to imitate what I think is a beautiful decorative look; the scraping look as we have on most of our classical machines in the school, such as on the Jig-Boring turn table. anyway more pics to come on this project next week, stay tuned!

We Know the Drill ;)

WEEK 2 & 3
Lathe: We know the drill ;)

Harman Wadhwa
Origin : New Delhi, India
Age : 28
Watchmaking class : 8 month Service & Technician course
Current mood : "Mind just got tapered.."started to use the Schaublin 70, loving the experience with the lathe. On Easter holidays, Henrik suggested to work on a school watch: I'm excited to work on the bridges over the weekends :D"

Pierre Aubert
Origin : Toulouse, France
Age : 22
Watchmaking class : 2Y Fullskill Program
Current mood : « Very exciting times: the lathe is an AMAZING tool!!! The precision is simply out of the world!! The love relationship with filing is getting very serious: I just started designing my school watch and filing the bridges. More on that later, stay tuned. PS: Filing might replace meditation ;) It is the purest form of self expression..!! The hands and the mind. What else? See you next week."


STEP 1 : LEARNING THE DRILLS 






                                                 STEP 2 : FULL CYCLE LEARNING
                   FIXING OUR OWN TOOLS (compound vice for the ACIERA 6T drill press)




STEP 3: TURNING
-
OUR CHAKRAS ARE ALIGNING!



(Trying to explain lathe operations :p)






STEP 4: APPLIED SKILLS
-
SCHOOL WATCH debuts




                                                      
HENRIK's WORDS

3 weeks has already passed as well as Easter!  Students are very efficient and seem to like even the filing! We covered already the drill press, learning on our beloved precision Aciera 6T column drill press, super smooth and most importantly no accidents! The students also started to work on their school watches mainly modifying 6498 bridges to classical shapes to continue practice classical hand filing, we also had time to learn the basics of the lathe on the the Schaublin 70 (watchmakers super lathe). Just before Easter I also met up with Mr. Simonin (former director of WOSTEP) to pick up some restoration projects.  We talked in length about marine chronometers and school watches, coincidentally he had one of my restoration projects that I did in the course on restoration and complications back in 2006, the marine chronometer that I restored, he still had it!! and it was in perfect condition still running strong! It was truly emotional ones again to be with it and hearing its beautiful song so healthy and strong! Anyway next week we will do some more cool stuff stay tuned...


Teaser for next week :) 

The Marine Chronometer Henrik restored back in the complication and restoration course in WOSTEP

Sweet memories.

Final Week!

We have finished the final week of the 2-year Fullskill course, some of us went ones again to check out the Basel World watch fair and others stayed in school or were busy packing and organizing, and finishing of last watches. 

These two years went by so fast it felt as if we just started! Also, good news for us; everyone successfully passed the final exam and no need for anyone to retake it. We also enjoyed a nice graduation dinner in a Swiss traditional style restaurant with awesome food and wine.

We hope the next students coming will enjoy the school as much as we did and wish all our readers great success whether it is in school, professionally or privately!

We will take a short 2 week break until the next students arrive. Stay tuned!
Below, enjoy some highlights from the last few days.


Best wishes to all our readers from the KHWCC Team!
