    Lesson 352: 4 of 5 defining qualities of a watch. These are my lessons on making watches I have learned and intend to follow when creating new timepieces. 4) Water resistance. The world today is different from what it was decades ago. The speed of life in cities now is in ever accelerating mode. And there are technical solitions around to help you to keep in with the pace. All high risks that can be completely eliminated by technology should be eliminated - like wearing glasses when working with flying bits and pieces, the iron autoswitchoff when not in use and many other things in our everyday life. Now as there is technology to make a watch waterproof, that should be done. Protecting our loved ones is a natural thing. I am sure the watch being one of most intimate items we have, should be protected equally well. Getting hit by a sudden heavy rain, leaving watch on a heavy moisture bathroom desk, accidentally jumping a pool with the watch on wrist, getting that stream from the tap hitting right on the watch while washing that cup. This is just a few to name that happen to watches every day. Knowing what kind of protection any level actually brings I call for minimum of 10ATM of water resistance, but preferred is 15ATM or 20ATM. This may mean screedown crown perhaps and a thicker sapphire (especially for larger watches) but thats OK - our precious ones deserve to be protected.

    The dual system students are back - this is their next-to-last session - almost three years of study and mentorship under their belts. They are at the same stage as the y2 students regarding the finishing of the escapement meter - almost done.
.
Here, Robert is using a screw polisher that he made to... ummm... polish screws for his meter! Actually, his preference is a fine, satin grained finish parallel to the slot, and you can see those last steps applied at the end of the clip where he moves the tool in a straight line.

    Lesson 351: 3 of 5 defining qualities of a watch. These are my lessons on making watches I have learned and intend to follow when creating new timepieces. 3) Crystal, the sapphire crystal. 
While diamonds can be the girls best friends, the sapphire is definitely guys (and girls) best friend when it comes to watches. For
a watch crystal, there are technically three options. A variation of plexiglass, often called acrylic crystal, then a variation of glass, often called mineral crystal and finally a synthetic sapphire called sapphire crystal. Of those the choice for us will be the sapphire. 1)Sapphire is extremely scratch resistant, meaning it stays clear and transparent for long years to come. From personal experience - 11 years and still clear. Another personal experience is four years and not a scratch. Yet another experience is 3 years and also
not a scratch. 2) When given extreme punishment, the watch crystal may crack. Some reviews say that crystal may shatter wheras mineral glass produces nice big shards or even just cracks. The other reviews supported by personal experience are different. I have seen at least 3 out of 3 times mineral crystal e.g. glass shatter really bad, meaning glass needles of different sizes being all over the place.
Sapphire usually produces a huge crack or two running through the crystal and thats it. To deal with a crack is much more user friendly than dealing with shattered glass.
3) The sapphire as a material is something that really puts some tangible value on the watch. I guess the feeling is easy to understand when you compare for example a cardboard with the wood or 1$ instant noodles to gourmet Italian pasta or say glass to a precios stone like the sapphire. 
So when it comes to producing watches, I want my customers to have this great feeling for having sapphire on their watch. 🐺 .

    One thing the school watch teaches can apply to real life repair - vintage work. If for example a barrel arbor has worn open the bearing in the barrel bridge, it would be centered in a face plate upon the hole in the mainplate, and then bored open for a bushing.
.
Here, Braydon is drilling the hole for the seconds wheel undersized in preparation for boring it until concentric to the mainplate. It will be left slightly undersized in order to ream it to accept the jewel.

    Lesson 350: 2 of 5 defining qualities of a watch. These are my lessons on making watches I have learned and intend to follow when creating new timepieces. 2) Strong case. 
A watch being most intimate item save perhaps the wedding ring is always with you. Wearing a watch you go everywhere: regular places (shops, offices) unexpected places (retrieving stuff for kid from behind that furniture), dirty places (going down on slippery autumn leaves), competitive places (getting beating in squash by that non-sporty looking colleague), high places (hold that beer, amma gonna jump from t’is roof), low places (to save these 30euros, I am I’ll try plumbing at home, DIY style), savage places (let’s go barcrawling wearing opposing team shirts), manly places (see how good my watch is, hit it with a hammer), dramatic places (say it again and after throwing my iphone at the wall the watch is gonna get it next) - in a word the life. Meanwhile the movement is dreaming about sitting in peace and tranquility in downwinded state on the everlasting safety of a watchmakers desk. The strong case of the watch, is its exoskeleton, its armor. Should be steel. Marine grade. Surgical grade. Noncorrosive. Indestructible. 316, 316L, 904 series or similar. This is absolutely necessary to take all this life that you bring down on the true satellite of yours on daily (and sometimes nightly) basis. I give you an example of good strong case - @victorinox INOX series. Stainless steel case of 316L marine grade steel. Though this Victorinox is not tunning on a mechanical movement, it still carries well the concept of a strong case. Does not have to be that rough, but you get the picture. The other pics are @omega Seamaster Professional and @hamiltonwatch Navy Pioneer. All having case made of 316L steel. Another great quality of the naked steel is that it can be worked by the watchmaker. To get rid of unwanted scratches, to make it new again.

    Lesson 349: 1 of 5 defining qualities of a watch. Tonigh we see the first one. These are  my lessons on making watches. These are the ones I have learned and intend to follow when creating new timepieces. 1) High readability. This a matter
of quality when it comes to telling the time. This what makes difference between blingy bracelet or armband or wristjewelry
and a watch. While jewelry carries a strong message and usually is that cherry on the top that completes an outfit, the watch is something different. Even when watch is the only thing you wear,  it always tells a story about you. And in the forementioned case when you are wearing
Adam’s suit, the watch tells
the whole story about you. Imagine a man coming out of a pool wearing nothing but a Casio G-shcock Mudmaster vs a man with an Omega Seamaster on the wrist vs a guy wearing a Sekonda having the now immobile hands on the dial slowly emerging from water as the watch drips dry, taking a long minute after the guy stands on the poolside. (a sidenote: If there is no emergency, do not swim with watches less than 200m WR). The point is watch is so much more about you then you are likely to imagine. And high-readability dial is saying - I value the function of thw watch as much a do value the form. Here are two fine examples os high readabilty - The Stowa Marine running on Soprod A10.2 movement (recently serviced by me) and a Hamilton Navy Pioneer running on an ETA 2895-2 movement (a gift). Both have excellent readabilty. While Stowa has 5ATM water resistance, Hamilton promises 10.

    In less than two weeks the Y2 students graduate, and the Y1 students have four more weeks. That means the watch repair requirements are about 99% completed, and the posts over the next month will be heavily focused on micromechanics, which is normal at the end of the year.
.
The Y2 students are completing their escapement meters - pics of those to come. The Y1 students are bringing their school watches to completion. Here, Eric has begun the terrifying act of beveling his bridges - the next to last step before full completion.

    Yesterday my son Tom and I visited as VIP guests 😀IWC in Schaffhausen. They took us from Schiphol- Amsterdam to the old and new factory in Switserland. Very interesting to see what time, effort and costs it takes to make these nice watches. We were already great fan of the brand but now even more. Unfourtunately not allowed to take pictures everywhere. Super lunch near the biggest waterfalls of Europe. They even let us do watch making ourselfs. Thank you IWC for this great day #iwc #iwcschaffhausen #iwcamsterdam #swissair #bigpilot #watches #schaffhausen #watchmakingschool #bestwatchintheworld #iwc150years

    The students in SAWTA schools also learn how to make blueprints, both by mechanical pencil on paper and by CAD. One way to utilize CAD is to import a photo of your workpiece into the CAD program, and then make design changes using the program.
.
In this instance, Brandan and JP are each making a long lever regulating arm (as seen on some older high-end pocket watches), that will hang over onto the center bridge.
.
This is their design - they designed the recess that will be milled into the center bridge - that slight kidney bean shape - it will be .30 mm deep. Then, they will mill the steel placket that will fit in as a mirror image. It will have indices etched into it, will be flat polished, and screwed in flush.
.
All the math coordinates are based being centered on the balance axis. And yes, they are both making chatons. More to come. 🤓

    Whaaaat? Doesn't Sam know what he's doing - how can he service a watch and have it so terribly slow? Well, Sam knows. When students work fast, work well, and meet all requirements, we allow them special projects. In this case, Sam is converting a 6497 stock balance wheel into one utilizing timing screws.
.
So far so good - four .25 mm holes were drilled (already a challenge), then each threaded with a tiny . 30 mm tap. The screws have more mass than the amount of metal removed via drilling and tapping, hence the predictably slow rate (heavier wheel).
.
Between poising and removing mass from the screws he will get the rate back to normal. Then, he will make an overcoil hairspring for it. Then, timing washers to adjust rate. If all goes well, it will go into his school watch.
.
The real purpose is to better understand timing theory - practical works supplements the theoretical. If he happens to get a usable wheel and spring combo out of it, that's just a bonus.

    This is Eric's school watch. It's "done". Done, meaning function over form: it has passed all functionality tests, and all shaping is done. That means that Eric can now devote all his skills to beveling/chamfering and application of high quality surface finishing. Then final installation of jewels, final cleaning, and final assembly. The students are not supplied cases nor dials so that they may obtain styles suitable to their preferences.

    Where are all the students...? Today was a big day - the students had their 2nd SAWTA exam - a complete service of a manual wind movement including full escapement adjusting and building a hairspring. They are either at various timing machines when this shot was taken (just now @ 3:45 pm), or hiding under their desk shaking and quivering and quietly mouthing incomprehensible things.
