Hi, I’m trying to replace the crystal on this expedition. I have pulled the stem and the movement. The crystal was shattered. It seems to be a 29.5mm crystal with a 1mm depth. I don’t see a gasket. How would I apply the new crystal? Does it press without a gasket?
Thank you for any help provided!
Hello guys. This is my last project – Seiko 6139-6010 aka Bruce Lee. Watch is from ‘69and it is based on the 6139A movement. Nice shot for the 50th Seiko anniversary of first automatic chronograph development. So please see the pictures below from all restoration proces. It took me 3-4 evenings.
The watch came to me as non runner. Crystal was scratchy with many chips. Dial was dirty and dusty with signs of water damages. Hands lost their lume. Day calendar was loosen and didn’t work properly. Movement was complete but very dirty and dry – there weren’t any residues of old oil in the jewels. Somewhere were signs of water flood. I dissasembled movement and I gave it a bath in ultrasonic cleaner then i’ve assembled and oiled movement. Star disk od date wheel was repaird with small amouth of resin glue. Movement had tend to stop sometimes. Inspection showed that the tiny chip on the bottom pivot of the escape wheel. It was hard to see it. After replacment movement ran as a champ. I polished the hands cause there was rust and gave them new lume. Dial was cleaned. I didn’t touch the lume on the hours indexes. I was affraid to screw up it. I think now it is quite good despite the fact that the lume does not glow. Orginal crystal was polished but I decide that in the future I will replace it. Case and caseback got some polish works only with polishing paste, not too much cause I didn’t want to loose the sharpnes of orginal edges – as usual I did it. Bracelet was matted with abrasive wool. Everything was mix up and combined and there is the result.
After measurments on timegrapher and adjustment it is a nice timekeeper. An amplitude satisfy me as well. Now I am enjoy to wear it.
Please let me know what do you think of this restoration project and about my works on it. I appreciate your comment and your spend time. Cheers folks
I want to show you my lately restoration project. This time it was a Seiko 7015-8000 with blue dial. Watch came to me in very poor condition. As you can see on photos the case was scratchty, crystal was totaly tarnished with deep scratches. Everywhere was dirt, gunk and mud...yuck. Movement was running and stopping with very low amplitude. After opened the caseback I wasn't suprised - it looked like as case - dirt and signs of wear. Rotor was loose and fall out the case. When I take off the crystall I saw dial which had faded Seiko logo, some scratches and hands which lost their lume.
Next step was strip down the movement - everywhere dirt and dry old oil. Time to cleaning bath
Look at this - it's my temporary balance wheel stand - I suspect that from temporary it will be permanent. It does job well.
After cleaning it's time to assembly movement. Now it looks better - maybe not pristine but clean and shiny. New oil here and there and movement starts to run. Now it's time for bench testing before install it to the case.
Meanwhile I took care of the case, dial and hands. Case got some polishing work - not to much cause I didn't want to loose the sharpness of edges. That is effect:
Dial and hands got new lume - I am not perfect in this work but I still learn to do this. Additional the seconds hand was repainted to orange color. I didn't change the crystall but i just polished it with waterpaper and on the end polish paste. Effect suprissed me. Time for the pleasant work - putting this all pieces together into the watch.
I'm a complete newbie and want to learn how to dismantle and re-build watches, specifically Seiko's.
Any suggestions on what movement to use as my first independent project to practice on and make loads of mistakes? Struggling to find recommendations on the different movements to use as a complete beginner and as my skills improve. Should i stick to only Seiko's or broaden my horizons?
Hey guys, my name is Lorenz. I am an 18 year old electrical engineering student from Germany.
I got this Breitling chronospace a56012.1 from my granddad and I want to repair it.
Besides a slight clicking noise while turning the crown ( someone please let me know if this is normal ) it works just fine.
My main problem is that the black color on the Bezel is worn out on some positions and I dont know where to find a paint that holds on the metal nor do I know how to paint it again.
I have worked with watches already, I disassembled a mechanical movement cleaned and oiled it again so I feel pretty confident in doing this job.
And I would also like to change out the crystal, does anyone know what size crystal I need for this watch?
Thanks in regards for any advice.

As mentioned, brand new GR mainsprings do not usually require lubrication. You have observed my videos on YT where I apply a little grease to automatic watches to the barrel wall. As has been mentioned above, this is braking grease. The mainspring also has an extremely light (and I mean extremely light) application of 8200 along it's length also. I do not film every aspect of what I do as some tasks are a royal pain in the rear to film. This is one of those tasks. Although I do cover this in the video course. The videos on YT are usually a 30 minute give or take condensing of a job that may last hours I cannot film everything. If you look hard enough you may notice many places seemingly not lubricated - this doesnt mean those friction points were not dealt with. My YT videos are there for entertainment purposes and whilst many find them extremely useful as a learning aid, they are not comprehensive breakdowns of a full service, that would make them hours long each., my course on the other hand is a full breakdown of all steps required to effectively service a watch. I hope this clears things up
In theory you can work ruby with anything harder or as hard (diamond is worked with diamond), but it's so easy and cheap to get diamond lapping compounds and powders that it's really the way to go. I'd suggest a copper lap rotated in the lathe, but almost any material is ok- acrylic, iron, etc. For pallet faces I would use 1micron diamond, it will cut slowly but surely and leave an entirely satisfactory finish.
I picked this little Russian up and was enamored by the dial. When it arrived I discovered it had the stout Vostok 2209 movement. I found it was a very clean movement and only needed to be adjust for timing just a bit. The dial that had my attention looked to be silver plated copper with a rather dirty looking patina. The dial isn't engraved as I had hoped, but was stamped with the pattern formed during that process. I wanted to make that pattern pop so I painted the entire dial flat black and used thinner to remove paint only from the top surfaces. Was a bit tricky to accomplish but I think it came out great. Next I turned my attention to the hands. Somene had put a shiny black varnish on the hands as contrast, no lume was present. So I cleaned that of and since I didn't have any white paint, I used liquid white out. I know this is probably blasphemous, but it's a totally temporary solution until I get some lume I like. Placing the hands back on was a bit tricky as the fit was incredibly tight and tough to accomplish with my huge sausage fingers. I have a black leather strap on order for it. Very pleased with the results. Thank you for reading this.
