Tutorial on watch repair by watchmaker Kalle Slaap from Chronoglide, Vintage Watch repair specialists near Amsterdam. Watchmaking documentary.
How to become a watchmaker. Where do i learn to become a watchmaker / Horloger.

I have a seiko quartz I’ve had for 46 years. The movement has ran for 46 years with no service. Very impressive. I have 3 watches with the Seiko VH31b mechaquartz 4Hz movement. Very impressive cheap movement that moves the second hand at 14400 bps similar to a mechanical watch.
I like quartz movements very much. What is the best quartz movement that you have worked on in terms of ease to work on and quality? And if an eco quartz movement by Citizen stops working, is it worthwhile to repair it?
Thank you,
Chris
So wonderfull to see the Omega Calibre 1310 being shown, which was Omega's first in-house quartz calibre. This is such a superbly engineered movement. Having restored a number of these I am a big fan, although coils are very rare to find now so dont let anybody not skilled with these change the battery as this is where they usually get damaged. Well serviced and correctly regulated they are very accurate.
Hello, thank you for taking the time to make this videos. I would love to see a summarized video of the repair w/o all the dialogue. It is quite difficult to stay focused with all that chit chat going on. Thank you again.
Seiko Grand Quartz before grand seikos are very nice.
Hi kalle can you do a videos on how to test your quartz movement
First (and unfortunately only) surprise was the sudden end after 12 minutes. Owning a bunch of Seiko King Quartzes I was very much looking forward to this. Hope there will be another one on quartzes some day.
Is there a longer version somewhere on Twichbook or elsewhere?
Very interesting, I recently had a complete quartz movement changed due to bent seconds hand which overloaded the old movement. Some chronographs are hybrids(meca-quartz) which have a simple quartz movement with a module which is mechanic . These basic lessons help us understand the working of quartz watches. As a comparison: some mechanical chronographs (ex. ETA- 2892 with a Dépraz/Dubois) have basically the same rough working. So please don’t snob quartz!
U explaineed how a Quartz watch work is only 40 % . Quartz Tuning fork vibrating @ 32 k & how IC make quartz to vibrate , feed back , flip flop etc are missing. Quartz movements without jewels are also durable .My Citizen Promaster & Seiko Kinetic 20years old. Still maintain +5 Second/ Month. I can check with my Atomic clock app on phone. & My wall clock with GPS module is atomic clock acuurate I turned normal Clock to this with a kit & assemled. People who scorn Quartz, either they are luddites or never understand electrics or electronics
The "blob" is a COB - circuit-on-board. The silicon wafer is attached to the PCB (printed circuit board) instead of being encased in plastic or ceramic. Connections to the traces are then made with very fine gold wire using ultrasonic welding technology and the whole thing is encased in a ceramic epoxy. This reduces manufacturing cost and size, making it perfect for use in a watch or other tiny portable device while at the same time increasing reliability because it removes one manufacturing step (the potential for errors increases with each automated manufacturing step). The negative aspect of this is that a fault or failure in the cob requires a complete circuit board replacement. If an IC is soldered on it has the possibility of easy replacement, whereas a faulty COB condemns the entire circuit board and probably the case to landfill. Not helped by the fact that I don't know of one watch company that is willing to supply their soldered on IC as a a service part (correct me if I am wrong).
As an electronics guy who is just moving into the field of mechanical watches I am torn. I appreciate quartz for what it is - a stupidly accurate means of timekeeping, but I deplore the disposable nature that the industry has mostly been going in and the lack of artisanal inspiration that is displayed by most of the industry.
Then I think about the fact that I can buy an (admittedly bad) quartz movement for $5 and put it in absolutely any case I desire even if I have to 3D print a movement holder, then recycle/reincarnate the case in 2 years when the cheap quartz movement fails. I am my worst enemy.
I love both, but for entirely different reasons, but both reasons are to do with the fact that I have done/will do all of this myself on my workbench. Average Joe Citizen doesn't even consider these aesthetics, he's usually only interested in a cheap but useful timepiece, and more often that not that is the free one on their phone these days. I'm now coming across young adults (up to 30 y.o) who don't feel comfortable reading an analogue watch face and would never consider putting a time piece on their wrist.
I guess I've just summed up the entire quartz crisis in four tiny paragraphs and doubled down on the smartphones. I believe that the love for mechanical watches and the history they represent is growing but I'm biased. I grew up in the mechanical watch age when strapping your own watch on your wrist for the first time was a rite-of-passage, but "came of age" while the quartz crisis was still in full swing.

Beste, u kunt natuurlijk een quartz horloge de hemel in prijzen, en ik moet toegeven dat Gucci werk ziet er mooi uit, maar afgezien van wat fysieke onderdelen zoals het cristal, de elekt.magneet, blijft de processor het meest kwetsbare. Niet te vervangen, ja alleen de hele platine.
Geef mij maar een mooi mechanisch horloge, nog steeds.
Tuning fork mechanism = shut up and take my money. Quartz, I still need convincing
Hello Kalle. Thank you for sharing with us your precious knowledge. The best channel for watch enthusiasts. Greetings from Israel 🇮🇱
Shit, begon net interessant te worden en nou wordt t wachten op dl 2 ….😉
No matter how experts you are on the matter itself, which at the moment happens to interest me very much, this an example of a poor video production, annoyingly loud music first and after that you can't hear almost anything.
You are right, this video is from a few years ago. We have changed things in the meantime. Point taken!
