Citizen Cosmotron X8: World's first transistorized electronic balance wristwatch?
ESA’s Dynotron movement of 1968 is widely-credited as the first to employ a balance wheel and a transistor, but evidence suggests that the Citizen Cosmotron released in 1966 was the world’s first electronic wristwatch with a moving-magnet type balance driven by transistor.
The example shown here was produced in December 1965, fitted with a 25 jewel Citizen 0802 movement. For more information on this particular watch, its restoration and insights into this technological blind alley, please see the post on my blog here: adventuresinamateurwatchfettling.com/2023/12/26/the-worlds-first-transistorised-electronic-balance-movement-the-citizen-cosmotron-x8/

Repair and restoration of a Seiko 6139 chronograph from 1974
Просмотров 3,8 тыс.Год назад
This video documents the restoration and repair of a Seiko 6139-8040 from November 1974. This is a warts-and-all account of a process whose conduct was severely hampered by its documentation. This restoration features a number of commonly-encountered faults that can afflict Seiko 6139 movements, the most conspicuous of which, a broken chronograph wheel discovered very late in the process. 0:00 ...
Changing the battery in a Grand Seiko SBGV009

Yes, a trivial undertaking but one that carries with it a small degree of jeopardy when the watch in question is as special as the Grand Seiko SBGV009, a 2014 homage to the original Grand Seiko Self-Dater 5722-9000 from 1964. Where the original Self-Dater was fitted with the hand-wind, low-beat 5722A, the modern reinterpretation is powered by the Grand Seiko 9F82A quartz, accurate to about 1 se...

Grand Seiko 4520-8000 from December 1970: a perfect high-beat, hand wind, three-hander. This model arguably marked the end of the beginning but also the beginning of the end of Grand Seiko, appearing at the half-way point in the first era of the brand.

Rotating the crown clockwise through a clear point of resistance causes the seconds hand to pause for a second or two, allowing the time to be resynchronised on the fly when the watch has been running fast. Similarly, rotating in the opposite direction results in a two second advance in the time, allowing correction when the watch has been running a little slow.

    Great video! I recently got my hands on a similar machine, the Elma SuperElite. Eager to try it! I noticed that you took out the pallet fork during the drying process to protect the shellac. Isn't it the same issue with the balance wheel impulse jewel? I read somewhere that it's also secured with shellac.

According to one of your articles, the direction of the rotor to wind the mainspring is unidirectional clockwise? I'm not an expert at all. I would like to know if in the settings of my winder, do I set it to unidirectional clockwise or bidirectional?

    Trying to understand this. The 2nd wheel has a hollow tube that projects through the main plate? And the 4th wheel pivot runs up through that hollow tube to turn the seconds hand? The cannon pinion slides over that hollow tube and has a gear at its base and that's turned by the minute wheel? Where does the hour hand fit in? You've got to have 3 separately turning parts here, one for each hand.

    My favourite watch the 62mas- it's one of those things that I just can't stop looking at, a bit like a Porsche 356. Can i ask, why do modern dive watches use a glass gasket and these only had a retainer ring? Im gathering the modern gasket is more effective? P.s If you don't want that new Bezel insert, ill have it...😁

    • @amateurwatchfettler
      @amateurwatchfettler 11 месяцев назад

      A modern watch can achieve 200m water resistance with an interference fit glass or sapphire crystal seated within a hard plastic gasket but in my experience getting the crystal to seat square is much more challenging than fitting a tension ring-equipped acrylic crystal or a glass crystal employing an L-profile a rubber gasket. These older divers were rated at 150m; modern divers easily to 200m. In either case though, those ratings are academic. Most wearers would rarely if ever need more than 50m water resistance.

      @@vanwilder1101 Yes, that's right. Acrylic crystals are flexible and achieve their seal by bending to the will of the rigid wall of the case whereas sapphire crystals are rigid and need a pliant partner to achieve their seal i.e. a rubber or nylon gasket.
