I am searching for a few 6602 movement screws, specifically the one holding the balance bridge and the one holding the cock arm. Can any one help please?

Nice to see a fellow Australian. The balance bridge and balance cock is the same thing. So that screw is obvious. You might need a photo to describe the second screw.

Thanks so much for answering my plea for help. The watch had been overwound, so to remove some main spring tension I removed the balance wheel cock and then the next cock that supports the pallet fork. The tension released OK but unfortunately, this shorter screw flew free, to a hiding place never to be found again.
I have tried in vain to find a Seiko 6602B parts list or a diagram to identify it.
I would really appreciate any help you can give me to identify the screw part number and where to obtain it.
The obvious alternative is to obtain another 6602B from a watch wreckers yard!
Cheers

According to the parts list that you have kindly supplied, the screw that holds the pallet cock arm is part number 022 256. Is that correct?
Now where do I obtain one?
Cheers

This is easy. You will find the same screw in the very common Seiko 66 movements. Just search Seiko 66 movement and grab a cheap one. This seller on ebay has a number of complete movments.


Just enter 66 in the search box in their ebay store.

Thanks Dan, but crikies that will cost AUD 80 to buy a movement and post it to Australia. That is an expensive screw Dan!
Where can I find a suitable screw from someones junk bin in Australia? Or buy a 022 256 from a local supplier?

A watch can't be overwound - well it can be but that would be breaking the end off the mainspring!
It has another reason for not going.
Many Seiko screws look / size the same as many other Seiko screws. I just get them out of my Seiko wrecks if I need them.
Is there someone you know (a watchmaker or jeweller) near you who has a dead Seiko or two you can get one off?
Beats wasting time, money and packing wastage to order one.

Thanks to you all for your help. The best watchmaker in central Brisbane is located within the railway station concourse building. The COVID 19 restrictions and loss of passing trade, have resulted in him closing his business for a while. Plus, purchasing online means that I can stay safely at home to tinker during this historic pandemic.
It is wonderful to have found this site.

Incidentally, I recently traded a Seiko 5 Sports 6119 8450 that I had bought on EBay, for a beautiful Seiko Solar V175 1/5 Chronometer 0DN0 on a Seiko stainless steel link bracelet. I did some research and it seems that this watch sold in USA as a 'Recraft Series' SSC513 on a leather strap. Am I right in believing that this is the same watch sold as a SSC511 that was sold here in Australia on a stainless steel link bracelet? And it came with a Jimmie Johnson card. Is this real?

Yeah that's bananas. I definitely have the screw, I have a full set of screws for the 66. But I'm not sure which is the one you need. If you can wait a week I will partial dismantle one of my spare complete 66s and figure it which is the screw and post it to you.

Thankyou for your help. The screw I lost is the one that secures the arm (cock?) that holds the pallet fork top bearing.
This screw is shorter than the screw that secures the arm (cock?) that holds the balance wheel top bearing. Does that all make sense?. The movement is a 6602B.
I look forward to hearing from you.
Cheers
Terry the Chronodome.
