Hello guys I've been renovating quite a few 1960s Seikos recently and a couple have shown very scattered traces on the timegrapher and generally ratty running after cleaning. All three responded to a new escape wheel very well. Being unable to see the wear using normal magnification I decided to try one of the £15 USB microscopes available on fleabay. They are too light, the software is hit and miss but glue it onto a heavy base and they will do the job. The difference between a good and bad wheel became obvious. The square corners get rounded off by the fork pallet jewels and precision is lost. The first two shots are from a worn 6602B and a 7625A Auto. Note the rough finish but 50 years ain't bad - neither watch back showed any servicing marks and were bone dry. The third shot is also a 6602 but it's a good performer - note square edges. The last is from my new baby - King Seiko 4402. Very different quality. Three lessons. 1. These devices are fine for simple close examination. 2. Don't neglect oiling the escape pallets - it's tricky but worth the effort 3. Once you've handled a part with your fingers it needs cleaning again - it's horrifying how many skin particles appear.

One of the great things about collecting and repairing is that feeling of taking a bunch of parts and making a working watch again. This restore begins with a scrap pile of cases from a former Timex repair center. I chose a late 1960's Marlin case that is missing the stem tube. So to the parts stash and one issue resolved. Off it than goes to get a bath in cleaning solution , polished, new crystal added along with correct case back. Next I service a used #24 movement also from the same lot the cases came with and the assembly begins. Since the hands are chromed, I just use an old eraser pencil to bring back their shine. The sweep comes from NOS stock. Grease the stem tube, set lever, insert a NOS stem\crown, snap on the case back and there ya go. Will give this one a wear to test its time keeping.

Hi guys, Sharing some pictures of my Seiko dress watch. It has a 6030 quartz movement (sorry no movement pics as I'm writing this at work) which from what I can find on the 'net is an 8 jewel movement and it has a trimmer screw to fine-tune its accuracy. It seems a decent enough movement from the pics on the net. What makes this watch stand out is the case which is made of a scratch-resistant material. Its pretty similar to Rado dress watches in terms of look and feel. The crystal is probably a sapphire crystal. The case-back is marked SHAC'(along with st steel back). I found some references that say it stands for 'Super Hard Alloy Case' but on one site someone mentions 'Super Hard Alloy Cobalt' which I think is much sexier so thats the one I choose! The first digit in the serial number is '0'so I figured it was from 1990 as the design was quite 'modern but I've since decided that its from 1980 as the movement seems to have been around in 1979. Considering it is 37 years old now its in pretty good shape with no scratches or markings anywhere! The mirror finish does make smudges from fingers more noticeable so I do catch my self constantly ''polishing' it! Its pretty thin as well and pretty unobtrusive when you strap it on. I'm not really a fan of quartz watches but this one will be staying with me. Anilv

Sounds like they do to some Timex movements. Sure it can work but i think i do it properly when i do it. I would remove the circuit board also.

welcome Matt. good show, enjoy the videos and perhaps buy a watch repair book. good luck, vin

Very unusual piece. Odd that Seiko don't list that abbreviation http://www.seiko.com.au/support/abbreviations#letter-S Not even on this more populated list https://www.plus9time.com/seiko-case-codes/

Vintage Seiko quartz watches are solid quality not like those Swiss plastic cr*p nowadays...

Hi Matt, Welcome. I think that almost any modern watch movement would be OK. I have never done Marks courses but I have no doubt that his courses are 1st. class. His knowledge and ability is superlative. I have another expensive watch to sort out for a friend who cannot afford the Big Boys. With Marks video`s and my copy of "Practical Watch Repairing" I feel quite confident of a successful result. If I were younger (76 now) I would certainly study with Mark`s courses. Best regards, Mike.

Progress ,…atta boy….

Thanks all! Turns out the front needed to be opened. After awhile I got it up, and it all good now.... Thanks again to all of you for your input! Sent from my Pixel XL using Tapatalk

I bought my wife a NOS ladies Vulcain for her Christmas a couple of years ago, and it's here everyday watch. It's also a watch name I like, and I keep hoping to pick up a Cricket sometime.
