  1. Hi Everyone, Recently I have become obsessed with ana digi watches from the 1980's! I really dig the style for some reason. I was looking on ebay in the low price ranges and I found this little nugget for the princely sum of $5.70 - the shipping from Peru was an inflated $20 AUD - so I got away with it for under $30. It came well packed in a little padded envelope. It was missing the back, had severe damage, but I didn't see any rust stains on the back. A view from the side It is a Seiko H127A-5000 - the year could be between 1979 and 1980 - there is a little bit of info around the internet. The case back will be an insanely rare part to find so I may have to CNC mill something or potentially 3d print a plastic back. That is if I can get it working. The Crystal is trash. I've tried sanding it, will wait till I have some crystal polish - I haven't had much luck polishing mineral crystals. A new crystal is around $35 - with OEM Seiko writing. I removed the movement and soaked it in WD40 to loosen all the bolts. It was too seized to attempt opening. The LCD panel/dial has a crack in it. The sub assembly appears clean, the zebra strips on the LCD were a bit gummed up but cleaned up. Happily the analogue movement was turning over freely, it wasn't ticking - but likely due to so much grit and much on the contacts. The only corrosion was on the rotor, and some of the non important chrome plated parts. I've soaked them in shellite. Cleaned with blutac and then inspected under microscope. Everything appears fine. It is a very high end movement with 8 jewels and all metal parts - it would have been top of the line back in the day. Very tiny parts. The main circuit board is out - my it looks complicated. Simple plain jane movement - nothing fancy: It's all inside: The bridge is off and the rotor is next to the movement: Cleaning the case: Tonight I have finished cleaning everything - I have put it into my movement parts tray - awaiting some time after work tommorow. If anyone knows how the LCD works please let me know - is the display in the top dial section? Or the next layer down? There is a white mirror presumably to reflect the light off the screen as this is the black model version (there were two models). Parts look pricey and rare - I've found a dial panel NOS - also crystals online. May have to look for circuit board if its fried - Can't find any bracelets - may have to go non OEM generic steel band. Goal is to get it running - if its not running - atleast to be a show piece in my cabinet. More soon

  2. 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.

  4. Hi Rogart, You start with 692 the flip to 629 ?? I believe that Eterna morphed into ETA. There is an ETA 692 and a 629 movement which may be worth checking out.

  5. I would agree definitely after 1883, although it would be nice to tie it in tighter than that. I remember reading somewhere that these clocks were made to counter the french slate clocks coming into the US, Ansomia also made cast iron clocks painted to look like slate and cheaper wooden cased clocks painted to look like slate or marble too. As oldhippy says not as good quality, or worth as much as the French slate clocks, but still interesting none the less

  10. Well, I'm certainly keeping the option on the table. The original intent was to restore the watches back to the original specification which would mean having the "correct" movement inside. I was hopeful that the only non-original parts would be the bezel rings. The 7002-700J was intended for a family member who has a particular affinity to things made in Japan. In this case the 7019 movement would still work as it was made in Japan (as apposed to Singapore) so I may end up going that route after all. It's a fine movement with cap jewels on the escape wheel and fourth wheel. I'm still routing around for a mainspring though.

  11. I know RAF sector clocks have recently become 'The in thing' and cheap reproduction quartz sector clocks are popping up everywhere which I don't have an issue with, but I do when an older clock is fitted with a new dial just to make a few extra pounds it annoys me. Atleast they do say it is a repainted dial in the title although no mention in the description. https://www.ebay.co.uk/itm/R-A-F-FUSEE-SECTOR-CLOCK-FULLY-SERVICED-AND-REGULATED-REPAINTED-DIAL/312008961077?hash=item48a52eec35:g:ELMAAOSwNchZ-hHq This one does state it is fitted with a new dial 'similar' to what was fitted originally to make it seem more like it was a real sector clock https://www.ebay.co.uk/itm/CHAIN-DRIVEN-FUSEE-RAF-STYLE-SECTOR-DIAL-CLOCK/112631887006?hash=item1a3962349e:g:I3cAAOSwH2VaAL-o I'm guessing it wont be long before more spring up and are attempted to be sold as original, or in 20 years time when the paint has warn a bit on these ones being sold as real sector clocks.
