Rubbish all parts that can be cleaned should be cleaned if it's for a customer. This discussion I have had before. You take the time to clean the plates that have screw holes so it is good practice to clean the screws. What is the point of cleaning the screw holes and screwing un cleaned screws into clean holes. Bits and pieces that you might not see get attached to screws so you should always clean screws. If it's your watch you can do whatever you like. It is also a good way of learning where the screws go.

Always helpful if you had a tech sheet or even the parts list because you can at least compare your screws the parts list to try to figure out where they may be perhaps go. Looks like the 7006 doesn't have a tech sheet but it's parts list refers you back to the 7005 so I've attached all of them. Then when disassembling a watch it really helps to keep the parts grouped together. For instance everything on the dial side can be grouped together. The automatic parts and if you're doing anything really complicated grouping the parts is really a nice way to keep your sanity.. Seiko-7005A.pdf Seiko-Parts-7005A.PDF Seiko-Parts-7006A.pdf

Very nice Seiko 6309-7040 slightly modified, with shark mesh...

Hi guys, My cousin learned of my interest in watches and passed me our grandfathers wristwatch. Its a nice hand-wind Mido, probably from the late 50s or early 60s...oddly a hand-wind. I say oddly as Mido made their name with their automatic watches..starting with the bumper 917 movement. It was probably in the middle range watch at the time going by the fact it has a stainless-steel case, with a Gold Bezel (not too clear in the pic above). It also has a dust cover which is always nice to have. It has a pretty large case tube as well. Back in the day there were many methods to achieve a good crown seal and a large crown tube allowed a large o-ring to be fitted inside the crown. The fact that the crown was missing is not really a problem.. many a watch has had the crown or crown/stem come off and been put away and forgotten in a drawer but the brownish stains around the center of the dial is not good. With the movement out of the case..you can see the brownish stains clearly. It comes away easily so it could be just some oil-residue (heres hoping!) so I proceed to remove the hands. If rust is present, removing the second hand may result in breaking the tip of the seconds pinion.. here I use my Bergeon hand-puller, make sure I keep the tool straight and press (to pull). That went well but....... ...In the picture below you can see the tip of the seconds pinion..and a lot of rust coloured 'stuff'. I'm starting to get a bad feeling about this. off with the dial and..... This is one of the worst case of rust I have seen..I pretty certain the screws will be pretty stuck but then again it may be so bad that I'll be able to break them while they're still in the screw holes..! Anyway this is as far as I'll go for now. I'll keep and eye out for a replacement movement.. this one is marked as a Mido 1020 which is basically a Peseux 170, not too rare so I'll be shopping for one at the right price. I may try to save the balance cock and barrel and train bridges to retain some of this watches identity but we'll see how that developes... the click screw seems pretty screwed too. One thing I just noticed is the cock for the centre-pinion is missing and someone substituted a spring. .. ah well, in for a penny... The only thing making this watch a viable project is that it has a stainless case, the dial and hands are usable, the movement is a fairly common one and lastly...the personal link to my grandfather (who passed on 30something years ago.

Click on the picture and then full size in the left lower corner and then click with the mouse again on the plus u have a picture that is large enough even for the bad eye sight

I would always take the movement out if changing the glass. Gives a chance to give the case a good clean with soapy water and a toothbrush. This one looks like it might be a sapphire crystal with a ring seal. With the movement out a plastic glass will normally push out with thumb pressure. Omega has a video on their website showing a sapphire crystal being removed with a hammer S

It is the life span of the watch...in seconds!!

So will the cheap Chinese one.

There's always more than one way to skin a cat OldHippy.

Can I make a further suggestion. Assemble all the bridges, plates, springs etc. without fitting any of the wheels or balance. That way you will be able to fit screws without the fear of jamming the movement or breaking a pivot. Check the lengths to ensure long screws are not fitted into shallow or thin plates causing them to protrude too far through. Once you have ascertained where all the screws are meant to go, carefully disassemble keeping the correct crews with the correct plates and bridges. Now assemble the movement properly.

Of course I would wash them, if you notice, I wrote "parts that are clean already". Anyway the watches I work with have waterproof cases and the movements always very clean. My approach is to use intelligence not inflexible rules carved in stone.

i say, your idea of taking pix at every stage of dissassembly - IS THE WAY TO GO ! untill you have more experience. vinn

Your eye sight is way better then mine. I had a job to see even with my glasses on that's why I could only give advice on the large screws.

My kids are gone so I now need to rely on zoom lens glasses I picked up in Italy. And you are correct, you do hear them drop and never find them. Sent from my iPhone using Tapatalk

Well I've lost my fair share. It's funny how you can almost always hear where they land when they go missing though. I think it's a bit of a tease since I can never see the darn things even though I'm certain I know where they are! I've discovered that my four year old daughter has exceptional eye sight though. She's handy to have around. Probably the worst thing to happen to me is when I dropped a steel spring on the floor. I knew I never would find it with my eyes in the fibers of the carpet so I used a Neodymium magnet which picked it up like a champ. Of course then I foolishly plucked the spring from the magnet with my steel tweezers. That shut me down for two days before my de-magnatizer arrived from Amazon. My friends, education is never free.

This could be useful for all other steps of your restoration. www.digitalwatchlibrary.com/images/seiko_manuals/A159A.pdf

I like it at the fraction of the cost and will keep good time too any normal person would say that's a nice omega your wearing now give it here or i'll hit you with a brick, whereas the omega community will think its against all that is holy to the gods off omega. But who cares there's often too much fuss made over high end watches and if your not going to try and sell it what's the problem.
