A 40 Year Old Citizen Robot Face Is Rebuilt From The Ground Up 

謝謝！祝你一切順利！

That may be true, though I've never had a problem, but don't take my word for it. Mind you, I only place it in the ultrasonic for 2 minutes!

Thanks! I will have another one fairly soon on another Citizen Ana-Digi. Cheers!

Thank you!

Well, that cup is really small and the shot is filmed with a Macro lens, but yea, it did end up being a bit too much :)

Hello Ton and thanks for your kind words. For your first question, these crystals are actually glass on the these Citizen models and are very fragile. There is a huge risk of cracking/breaking them, therefore a crystal press is necessary if you want to achieve a good seal and an even fit. You really have to be very careful doing it, even when using a press. Ensure your crystal and your case are completely flat and do it very slowly. An extra layer of protection via a plastic bag would be a good idea. If you can, order 2 or 3 crystals and there's a large possibility that you'll end up cracking one the first time around. For your second question, I'm sure there are many places in the EU which offer the replating service, but since I'm in Canada, I'm not aware of any in your region. I get mine done in Canada, (Montreal to be precise), at a place called "ReplateIt". You can find them by going to www.replateit.com. They offer a very good service at a very reasonable price. Just be aware that your case has to be finalized and ready for replating as that's all they do. This means all sanding and filing and removal of any scratches is your responsibility. They just plate the part. Hop this helps and good luck!

Hi Rocco, it came with the lume powder. No specific brand. Cheers!

Yes, sometimes this type of work is almost a health hazard! 😂

Hi there! That 'half circle" is the piezo speaker responsible for the beeping sound of your watch. The little spring is the contact between the positive terminal on your logic board and the above mentioned piezo speaker. The "half circle" part of that speaker, meaning the thicker part should be the one making contact with the little spring, so that's how you position the case back. Good luck!

@@grumpyswatchrestorations Thanks. Great information. I'm excited to see if I can get this watch functional. I was able to find instructions for this movement online. Hopefully a new battery does the trick. Cheers.

@@mtbbiker6401 Sounds good and good luck! Let me know if you have questions.

@@grumpyswatchrestorations Hi. After installing new 391 battery in 8940 the digital portion is working but the analog is not. I'm also missing the battery strap you mention at 43':40". Just wondering if I need some sort of battery strap to make a connection from the (+) battery to the quartz circuit?

Okay, the analog hands would not move when trying to set the time with the pusher. I freed up the gears. Now I can set the time using the pusher on the side of the case, but the hands still do not move on their own. Since I can move the hands with the pusher, do you think the quartz circuit is okay and the problem is more mechanical in nature? Also how does the minute hands move normally? Does it move in minute increments or slowly like a regular quartz? Should I hear a "tick" for every second? Actually it looks like I am getting some movement of the minute hand but very slow so maybe the drivetrain is gunked up.

Thanks! I don't buy them. I have all the ones I want which have been restored. Your watch could exhibit a couple of issues. Previous battery leaked and damaged the logic board, logic board may exhibit damage from age, the battery contacts are corroded, etc... Very few watchmakers want to touch these watches these days due to lack of parts. Cheers.

Hi Ross. Getting these fixed is pretty hard these days as most watchmakers don't want to go near them due to lack of parts. I use parts from broken donor watches I buy on ebay. With regards to your watch , it all depends on what the issue is. If it's a battery spill, new logic board for sure and that's just to start with. You could have a bad LCD, bad coil and so on. At the very least you just need service with cleaning and oiling. There are Citizen groups on FB, and someone may be willing to take on the job. I'm just too tied up at the moment to work on viewer's watches. Good luck!

Thank you so much for your time.

Hi Jay, unfortunately at the time, I do not do viewer's restorations. I'm working on a watch for a viewer as we speak, but that's a one off. Due to time constraints, I don't accept any jobs right now. My apologies.
