Hi.

Hmm introduction to my self.

I have always been intrested in how mechanical and electronic stuff works. Like to tear down to learn how and hopefully putting it back together working.

Have done some old sewing machines, snowblower, bicycles...

I am an electronics engineer and working with system verification so a lot time is spent in an office infront of a computer. So to satisfy my need for practical work I have now turned into watches since i do not have the space for larger projects. It started with a birthday gift for my father inlaw who wanted a new watch. So my mother inlaw picked up an automatic Seiko that we contributed to. Me on my hand is more of an Swiss watch guy, owning two Certina and going trough old stuff after a recent move, I found an old Longines that I learnt belonged to my mothers father that I sadly have no memories of since he pasted away too early. Felt that I wanted to restore that old Longines so I had a Longines dealer have a look at it and got an estimation of 1900 euro too restore it since they would send it to the factory. Since I am on parental leave, 1900euro is not what I can afford for a clock that is running but need a good clean and serviced back to water resistance. So here I am, looking for options to ultimatly restore that watch. The plan is to get a setup for a small diy watch repairshop, train on some watch without sentmental value and go from there. 

I have an alternative price for servicing the Longines at another dealer for 400 to 600 euro that I may do if I find my hands too shaky. 

 

Future will tell...

Latest is that i have bought some watches, some equipment and some movements for repair.

Still looking for info on oiling, cleaning fluids, glass replacement and service instructions/parts sheets/movements documentation for Certina, Longines and Tissot as these are the brands I am focusing on to start with.

Hi Bjorn,

 

I would suggest getting used to taking a watch apart and putting it back together, before worrying about cleaning and oiling it, just to get used to using tweezers and screwdrivers.

A good watch to start with would be a Molnija 3602 or a Seagull ST 36, because they are big and easy to work on, but also relatively cheap! (£30 to £40) The Seagull is a copy of the ETA 6947. I teach watchmaking and this is what I get my students to work on first. They don't go near a cleaning machine or oiler until they know how to disassemble/assemble a watch and know how it works. If you already have some old watches to work on, that's great.

I've attached a schematic of the ETA 6497, to get an idea of what the parts are and eventually where to oil and what oil to use.

If you ask 10 watchmakers which oil they use, you'll get 14 different answers, as it is very subjective!

Cousinsuk.com are a great source of downloadable movement schematics for watches, just put the movement number in the search box and hey presto: https://www.cousinsuk.com/document

I started cleaning with lighter fluid as a cleaner and isopropyl alcohol as a rinse and using these cheap pots from cousins to clean them in: https://www.cousinsuk.com/product/aluminium-pots-in-cardboard-box or use some ramekin dishes, if you have any spare

      Balance wheelwheel crooked

      By mikepilk · Posted

      As with every skill it watchmaking, it takes practice. Notice at the top of the document it says, "Practical work - 40 hours".  I can get the balance wheels 'close enough' to flat, but never seem to get them perfect. Same with gear wheels. Guess I need more practice.

      Beat adjustment

      By transporter · Posted

      Has it got a beat adjustment on the platform or is it a fixed hairspring? in short what you are looking at to get it just about in beat is to get the roller jewel sitting dead centre between the banking pins. So remove the platform and take of the pallet fork and escape wheel to give you clear line of site, sit the platform with the balance in place and with it level look between the banking pins and see if the roller jewel is sitting between them, if it is nice and central its there or there abouts in beat, if its not the the position of the pinned end of the hairspring needs to be adjusted to move the roller jewel into the correct position, thats why I asked if it has an adjustment on the platform or not, if it has its an easier job.

      Help - London Elliott Mantle Clock Night Silence

      By MapleWood · Posted

      I've managed to adjust it. I'm going to try and explain it as well as I can with my limited horology knowledge but I hope it helps someone in the future. There is a cam to the right of the front plate as shown in the picture. As the clock ticks along, the pin indicated in the gear comes around and slots into one of the silencer cam gaps, turning the cam. The pin completes a full rotation in 2 hours. To adjust the cam to start at the right time set the clock to just before 7. I did 6:45. Then I turned the silencer cam anticlockwise, which spins freely, until it pushed the silencer lever up and was placed just before the drop. Just before the 7AM indicated in the picture. All I then had to do was progress the hands to 7-7:15which made the pin slot into the silencer cam gap and turn the cam so the lever comes down again, unsilencing the clock. That was it. If anyone comes across this issue again I'd be happy to assist. Thanks again to everyone that helped. Hey Transporter! Thanks a lot for the reply. That was a really good explanation and I'm sure it would have made my troubleshooting a lot less painful haha. I'm sure someone will find it useful in the future. Thank you again for taking the time to try and help me out with this.

      Epilame / Fixodrop

      By Waggy · Posted

      Now I'm completely confused, it would appear that the epilame  is oleophobic  as @Marc states: This oleophobic  behavior can be seen as beading of the droplet (as above) which stops the oil spreading which is supported by what we observe on treated/untreated cap stones (for example), but as @VWatchie states this should make the drops more mobile and is supported by the literature:   A review on control of droplet motion based on wettability modulation principles design strategies recent progress and applications.pdf   However the hole point is that we have less mobile oil so an oleophobic  would see to be the opposite of what we want. In fact this beading and high mobility are desirable properties in things like smart phone covers, see below.  I am fairly sure that epilame doesn't make the droplets more mobile, so maybe its a strange coating with dual properties that are both oleophobic (beading) and cohesive/adhesive resulting in low mobility?? This may explain the high price??

      The description there is exactly how it's done, and it's very well written!
