I want to show you my lately restoration project. This time it was a Seiko 7015-8000 with blue dial. Watch came to me in very poor condition. As you can see on photos the case was scratchty, crystal was totaly tarnished with deep scratches. Everywhere was dirt, gunk and mud...yuck. Movement was running and stopping with very low amplitude. After opened the caseback I wasn't suprised - it looked like as case - dirt and signs of wear. Rotor was loose and fall out the case. When I take off the crystall I saw dial which had faded Seiko logo, some scratches and hands which lost their lume.
Next step was strip down the movement - everywhere dirt and dry old oil. Time to cleaning bath
Look at this - it's my temporary balance wheel stand - I suspect that from temporary it will be permanent. It does job well.
After cleaning it's time to assembly movement. Now it looks better - maybe not pristine but clean and shiny. New oil here and there and movement starts to run. Now it's time for bench testing before install it to the case.
Meanwhile I took care of the case, dial and hands. Case got some polishing work - not to much cause I didn't want to loose the sharpness of edges. That is effect:
Dial and hands got new lume - I am not perfect in this work but I still learn to do this. Additional the seconds hand was repainted to orange color. I didn't change the crystall but i just polished it with waterpaper and on the end polish paste. Effect suprissed me. Time for the pleasant work - putting this all pieces together into the watch.
I started new project - Citizen 67-9119. It's seventies chronograph based on 8110A movement. Watch came to me as "fully working in great condition" As you can see there isn't crystal. The one which was here had chip and wasn't set properly in bezel so when i turned the watch it fall on the floor and broke. As you can see dial is in quite good condition, only it needs to be relumed. Hands needs to be repainted and relumed too. Movement works well but it is too speedy ( +3 min/24h). Chrono buttons work properly, only the hour counter stops at "3h" position so I must to take a look here. I striped down the watch and disassembled movement. There was some much oil everywhere so the cleaning is required.
I open this thread to archive works on Citizen 8110A Bullhead. I purchased this watch in poor condition as You can see on the photos.
Cause I have serviced few chronographs in the past I decide to try restore this watch. Maybe is not ractional from the economical aspect but we do this because we love it So let's open it.
Hands are in good condition (required repaint and relume) but the dial has broken legs and tachy scale is faded :/ I think it's really hard to find orginal and there is no gold aftermarket replacement - sad. Look at the movement.
Gosh, what a dirty place It needs good cleaning and oiling. But the biggest problems are this.
Broken post on main spring bridge and missing rocking bar core and screw in gear train. I need to find replacement.
While I'll be working on movement the case and pushers are send to renew - putting new gold plated coat
Hey everyone, I cant find out how to get this drown off and I've tried everything. The Miyota JS25 movement says PUSH and points to a hole which I've learned means this is where you press to reease the crown but I still can't get the crown out no matter which position the crown is in. I first tried with the crown all the way out then with it halfway in, then all the way in and haven't been able to get it out, please help.
Why my seiko speedtimer 7015 chronograph run smoothly when its day(morning till evening)
But its stop and heavy when its time to changing the day date,whats the problem and how to fix it..
I knew that Ronda offers Swiss made movement and Swiss parts movements. Typically the gold colored movements are Swiss made and the silver are Swiss parts. Out of curiosity, I popped the back off and.... Ronda 515... Silver plates.... Swiss in spirit only, lol. Thanks again @yankeedog
Well my Florida brother. I hate to burst your bubble, BUT. Your pro diver may or may not have a swiss movement..most likely it is a ronda 515...which may or may not have come from Thailand. Ronda,a swiss company outsources there.some 515s are swiss,some are Thai. With invicta it is really the luck of the draw. I like your kirovskie idea. Just be aware that that watch is not shock protected..so you can NEVER drop it.A quick look at them online reveals a movement that I think is a poljot 2409 with without shock protection...these movements run well for a very long time. A have a few that came in cheapo sixties watches,that run as well or better than my cheapo swiss watches of the same era.
I just got this one and of course the crystal needs to be polished out, but the question is what battery did it take and how is it supposed to stay in place? Is there a battery holder missing? I can set a 39- negative down on it and press the back on carefully and it will run since the positive contacts the case, but surely that isn’t all there is to it. Has anyone else seen one like this? Steve
There is a clip in ring inside the back cover that may be part of the answer.
