In this video Mike looks at a genre of watch movement long forgotten. In those early years of the 70s where quartz was becoming a real proposition for time keeping. The Evolution of horology brought us a transistorised electronic watch that uses a mechanical movement and balance for its timekeeping. Watch as Mike tries to fix this Citizen Cosmotron from the 1970s.

About me:
My name is Mike and I am a hobbyist watchmaker. I am completely self-taught in watch repair and restoration. My channel is all about my journey of hobbyist of watchmaking. I have watch repair tutorials, watch restorations and watch repair videos. Some of my content you can easily follow along to if you are working on the same watch movement. My main focus is to document my journey and inspire more people into this wonderful hobby and demonstrate that this hobby can be very rewarding. I do not profess to be a professional watchmaker and in my videos, I show all my mistakes, mishaps, highs and lows and keep everything as honest as possible. It is easy to edit all the mistakes out and make my videos look perfect but I believe that keeping it real reflects the true reality of this hobby. So what are you waiting for? please check out my watch repair and restoration videos, get inspired and start your own watchmaking journey.

A little bit, but unless you’re spending $$$$$, microphones and typical recording software will amplify background noise, or any noise it can get, if there’s not much going on in the foreground. It’s tough for the type of recording we do

@wirdy1 2 месяца назад

No quartz, it's transistor driven & more akin to the ATO licenced clock movements of the 1960's. On all these types the balance pivots are under a fair bit of strain due to the weight of the two balance magnets. Still a great piece of history 👍

@MyRetroWatches 2 месяца назад

No quartz although they were emerging at the time of this watch. I still prefer the Seiko Elnix to this Cosmotron but both have been satisfying to work on and understand how they work.

@El1988Che 2 месяца назад

I'm pretty sure it was Hamilton who came up with this concept. On 3 January 1957, the American brand Hamilton Watch Company revolutionised the watchmaking sector by presenting the first electric watch in history: the Ventura. Its design was futuristic at the time, and today it is a celebrated icon. The innovation resulting from 10 years of research is technologically unprecedented! The Ventura represents a major evolution in watchmaking since the creation of the mechanical watch. It is the very first mechanical watch powered by an electric battery.

It would be interesting to see a review of the Swiss ESA 9154 Dynotron movement, which was used in many electromechanical watches of that era.

Outstanding. I recently came across that incredible quick day date change doing a mechanical citizen seven star v2. Quickly made it one of my favorite watches! I also noticed the facets on that crystal on the outside. I always was under the understanding they were on the inside of the crystal. I have one of those that I have to polish and I'm not looking forward to it!

@MyRetroWatches 2 месяца назад

I did a video on a 7 Star Deluxe over a year ago now, it didnt have that setup but was one hell of a tricky movement! ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-rMfBm5k7yGs.html Facets are mainly glass crystals and cut on the outside. Seiko mainly used glass although I do have a Seiko with an acrylic one with them on the inside. Also in my Ricoh video those were also on the inside. The beauty of the acrylic ones is you can polish them up in minutes but the glass ones are impossible. The glass I prefer though as they just look so good in the light

@yanholland315 2 месяца назад

Nice, great to see an unsual watch movement altlhough I do have a thing for the X8/Cosmotrons. They are very unique movements and they 78xx series is a much more refined design compared to the 08xx or 48xx - these still use a pallet fork and are closer to the Elnix. Since your Elnix video the Japanese tech docs I had on a boat have arrived. I'll stick some translated images on the FB group page but couple of random things stuck out. Beat error isn't set like 'normal BE' you actually need a gap due to the way the watch is driven backwards. If you look at the mainplate where the escape goes there is a tiny magnet that 'locks' the escape in place - this covers the lack of pallet fork and the wierd BE setup. The watch should kick out 180-260 horizontal and 160-240 - there is a handy little diagram of balance for reference. The A and B markings on the mainplate are for the auto hack found on the 7801, single pusher will set seconds hand to zero of its 0 seconds minus 3/plus 3. Great work as always, I've got an 'electric' Timex which looks a lot like the Hamilton/Ricoh setup - that lools wierd too!

@MyRetroWatches 2 месяца назад

Id welcome any docs you have movements like this . It helps me plus I can put them up on the group and my site. I did see the B and the magnet bit dismissed regrettably . I am sure I have this setup wrong as it already has an issue in that firstly the second hand does not beat like a high beat, could be normal I guess? Also despite a contestant Timegrapher reading it seems to loose 30 seconds in 12 hours . Maybe this is as you are saying about the setup. It could be I do a follow on video on this setup so if anyone else is doing this movement for the first time they can then also figure it out correctly. Thanks

@Tom_Kowalczuk 2 месяца назад

You did good. Look at you!. Do whatever watches you like, Mike. Maybe if you run into an older early 70s quartz Seiko like the 3803 series. But this was another fun watch from Mike. Mike Bolton. "That _was_ a good name until I was twelve-years old, and that no-talent ass clown started winning Grammys" -- Michael Bolton played by David Herman from the classic comedy Office Space Btw, Hamilton was the first to come out with the electric watch in 1957. The Electric 500 was the first one to come out with a battery to power a balance wheel instead of a mainspring. It has a wacky design with respect to the battery hold down spring making it easy to destroy the watch by slipping and ramming one's finger through the critical thinner-than-hair make and break circuit wires that power the balance. Therefore, they changed the design of the battery hold down within a year or two.

Just repaired a seiko elnix similar to this. Then bought 2 cosmotron x8. On x8 the electronic block and magnetic coil are 2 seperate pieces. hoping to get 1 running. But what a nightmare. They both different and both seem to have the same issue. The magnetic coil are both burnt out. Been looking ever since for this part. No luck. Rather buy one running if you want to get a cosmotron.

@MyRetroWatches 2 месяца назад

I love the Elnix and actually just completed another tonight. I did a video on them a while back but at the time it didnt get so much interest. This Cosmotron was interesting and I have since learnt today that I have setup my balance wrong in regulation so I still have work to do.

@Ranaldi0227 2 месяца назад

I don't suppose you have the spare circuit board from your donor watch? I have had my cosmotron for 6 months now and all I need is a new circuit which are very hard to find. I Love the design and would like to get it on the wrist 😊

@MyRetroWatches 2 месяца назад

Sadly not the donor parts I didn’t use go back to my friend who commented that it was the board was faulty. It didn’t matter to me. Japan yahoo auctions are awash with Cosmotron

I have two of the lesser Crystron's, sadly the second of the pair died when installing the crystal in situ and kinda killed the movement when the crystal turned out to not be as advertised and a bit over the measurement (seems to be quite common with ebay crystals where folks buy a set, use one and put in willy nilly the ones they don't use, return to seller who then sells it as such and such size and its not :( ) My other one is a 7300 but not the "mega" and can't get into it as caseback is welded to the movement through dirt and age, had it soaking in some isopropyl and then some naptha but that is not coming off without some heavy levering :*(

One observation, despite the high beat of 36000 per hour, the second hand only ticks 6 times per second. I have counted it. I guess the high beat doesn't always translate into how smooth the sweeping action is. If someone has more info on this, I would love to hear.

@MyRetroWatches 2 месяца назад

That’s correct on this one. The Seiko elnix look smoother. I was a little disappointed with the high beat movement and less than smooth tick

@keithshergold9257 2 месяца назад

But what makes it go? I see the balance is powered by the coil, but there’s no escape wheel or pallet fork. How is the motion of the balance transferred to the train of wheels without an escape wheel?

@MyRetroWatches 2 месяца назад

The whole thing like the Seiko Elnix runs backwards. The battery pluses the coil which in turn reacts to the magnet on the balance wheel. This swings and has an impulse jewel on it like a normal balance that moves the star shaped wheel that I at first fitted upside down. That wheel moves (also a magnet on the main plate I believe. This then moves the first brass wheel which in turn powers the main train on the top layer.

@MyRetroWatches 2 месяца назад

The star wheel is essentially the fork and escape

I wonder if it is the crystal that caused the damage on the dial? Kind of like a magnifying glass.

Мне нравится смотреть видео этого влюблённого в часы чудака . Возможно потому , что я в часы влюблён давно и эта любовь не проходит . Я преклоняюсь перед человеческим гением и его творчеством , доведённым до уровня искусства . В данном случае часового . Хоть я не вижу лиц инженеров , конструкторов , дизайнеров и исполнителей, создававших всю эту красоту , но плоды их творчества продолжают согревать моё сердце . Автору видео благодарен за популяризацию того , что раньше не было доступно всем . Как ни странно , на моей левой руке сейчас СЕЙКО 5 . А на полке СИТИЗЕН , ОРИЕНТ и не только .

Спасибо. Дизайнеры механизмов и циферблатов часов проявили творческий подход. Мне нравится снимать видео о доступных часах. О часовом механизме Citizen нужно говорить, поскольку он является частью истории часового искусства.

@gang208 2 месяца назад

This watch may be "high beat", but the way the second hand moves looks more like a 18000bph watch.

@MyRetroWatches 2 месяца назад

Yes I have noticed this and contemplating why, could be that it’s not the original hand. I might put the stub one on and see how that rotates.

@gang208 2 месяца назад

@@MyRetroWatches I believe it's due to the different escape mechanism. If you look carefully, the second hand only advances on every other beat. So, even though the watch beats 10 times a second, the second hand only moves 5 times/sec.

Technically quite fun and a great repair! But there's no arguing about taste and color. Still, I find this watch bulky, too heavy with hideous hands and a hideous dial. I don't want to think about reading the time through such a glass. In short, I wouldn't have thought for a moment about wearing this thing.
