    NMarsh got a reaction from Johnnie in Newest acquisition and first automatic.   
    Found this wonderful Seiko 7625-8021 Sea Horse at a local estate sale for real cheap and had to snag it. It has the usual light wear and tear, but nothing that bad or that can't be buffed. The original band was busted on it unfortunately, missing the clasp, so I tossed on a temporary band (the only one I had that would fit it). It started ticking away right when I picked it up and so far has kept perfect time over the last 8 hours. After a few more practice watches I will attempt at giving this one a thorough cleaning, until then it may stay in the case to prevent running it dry for too long.
     
    Now for some pictures.

    NMarsh reacted to Tiktok in Cleaning fluids for ultrasonic bath   
    If you are using a ultrasonic bath rather than a  multi jar cleaning machine could you not use water in the bath but then place your parts in a separate container with the chosen cleaning fluid in it and put the full thing in the bath, then you could use a simular container for a rinsing fluid and just transfer the parts.
    Containers you put your fluids in could even have a lid on to keep the fumes under control. You can also only use a smaller amount of fluid, rather than filling the full ultrasonic with fluid.

    I appreciate it. I attempted to throw it on my "Timegrapher" aka the Watch Tuner Timegrapher app on my ipad with a mic to see how it was doing.  I honestly have no idea how accurate the app is, I am guessing it is not terribly accurate just using a stock headphone mic catching all the surrounding noise but this is what I got from it. 
    Not the prettiest but my setup isn't exactly the most accurate setup either.

    I also like it.  
    Don't try to regulate it until it has been properly cleaned and oiled, you may well find that it runs perfectly after without much or any adjustment.

    More accurate definitely. But will also take long. Most cases now a days the patient will have a pulse-ox on that will read pulse and you would just read the screen so accuracy isn't really needed, primarily because he likely won't ever actually check and count a pulse.

    The only time he would be checking a pulse manually, will be in emergent situations. In which case you likely need the fastest way to asses pulse which would be base 10. The only other time he will be checking pulses would be in extremities to just check for the presence of a pulse rather than the rate.

    Pretty much you count 10/30 beats of the heart and whatever the number on the pulse tach nearest the second hand is the pulse. So on the base 30 watch that I posted I would count 30 beats, and say the second hand was pointing at the 5 o'clock marker. That would make the pulse 72 bpm. Does that make sense?

    Have they banned neck ties yet? At least those have been shown in some studies to cause unnecessary germ exposure. I honestly don't know what I would do in the hospital for time if I didn't have my watch.

    As a medical student myself I would agree with rogart63. I have been really wanting a wristwatch with the base 10 pulse grading. There are a bunch of different brands that make them, some much older and less showy as the seiko pictured. I fell in love with this base 30 medical wrist watch that I saw on Instagram a while back.



    A pocket watch is an awesome gesture, but it wouldn't really be of much use. Our pockets are already stacked full of papers, pens, stethoscopes, books, and snacks. I would fear that anything too nice would get damaged pretty quick.

    Wish your brother luck, and tell him that there is much greener pasture on the other side. 3rd year is much more enjoyable than the first 2 years of medical school, even if you have to take step 2 afterwards. And be understanding that the stress the month before that test is miserable. I studied roughly 15 hours a day, 6 days a week for a month.

    I wonder if you could get a small piece of pith wood down in the bottom of those oiler sockets. That would help keep them clean and would wick away any extra oil left on the oilers.

    NMarsh reacted to Dynam0humm in Seiko 6105 Saved From A Watery Grave   
    Greetings all! My first post here so I'll try to start with a good one...
    I've been fixing and servicing watches full time for a few years now but this one that came in recently is probably one of my biggest saves. It belongs to a guy called Paul who's a pretty serious Seiko collector and sends me a couple of watches each month for servicing. He spotted this 6105-8000 on ebay which appeared to be in good cosmetic condition but was listed as non-running / needs a service -
     
     
    There was no picture of the movement with the seller saying the back was too tight and he didn't have a case back tool. Paul took a chance on it but when it arrived the case back was only hand tight and this is what he was greeted with - 
     
     
     
    Now obviously Paul wasn't happy with what he'd bought and was going to raise a case with ebay, but in the end he decided to keep it and send it to me to see if it could be saved. 
    Now I mentioned that Paul is into his Seiko's but he's also a great customer. When he sends a watch that needs a new crystal for example he sources it first before he sends it to me which then saves me having a partially finished watch on the bench while I search for a crystal and then wait for it to be delivered. Most customers won't even think about this but if you fix watches or cars or whatever for a living and a customer comes in with all the parts needed it saves you so much time and hassle.
    With this one he had a good stash of 6105 parts so they were sent with the watch - 

     
    So onto the strip down... The dial side wasn't too bad but pretty much all of the screws on the train side were rusted in place, so the movement was placed in a tub of penetrating oil and the tub was placed in the ultrasonic cleaner to agitate the oil. It spent about an hour in the cleaner like this and soaked in the oil for 24h -





     
    So after soaking for 24h it was time to start the strip down. The auto winding bridge came off easily enough but the train wheel bridge screws were very tight and I couldn't get enough grip on my Bergeon screwdriver, so I used an electricians terminal screwdriver and ground the tip down to size on an oil stone for a bit more torque on those stubborn screws -

     
    The click spring had dissolved with rust and turning the screw on the ratchet wheel only turned the mainspring so it was out with the Dremmel - 




     
    The strip down wasn't totally straightforward as the heads on two of the screws had corroded away. One of the screws was on the train bridge but there's still two other screws holding it in place so not a problem and the other one was the dial foot screw, again not something that is critical to how the movement performs. The main thing was that the main plate could be salvaged as this is the one movement part that isn't readily available.
    With everything stripped it was back into the cleaner again and then inspection. Obviously a lot of parts would be replaced but it wasn't as bad as I'd initially anticipated. The parts above the mainspring in this next picture are all reused and below it are the scrap parts -

     
    From the state of the movement I suspect it had suffered a crown gasket failure, taken some water on board and was then left dial-up for the movement to soak for a few years, as evidenced by the back of the movement being a rusty mess and yet the front and dial were pretty much unscathed. The state of the train wheels would back this up with the top pivots being corroded yet the bottom ones were fine. The balance was the same and I thought I might at least be able to save the hairspring but there was some rust or rust residue on it and it was beyond mine and my cleaning machines ability to remove it. Not a problem I thought as Paul had supplied a complete nos balance but it wasn't going to be so easy - 


     
    I tried straightening it out and got it looking like this -

     
    Not bad but far from perfect but when viewed from a different angle it looked like this - 

     
    I've fixed a few bent hairsprings before but twisted ones are beyond my ability, so it was into my own spares stash to harvest a hairspring from a 6139. The only thing left to do now was to put it all back together - 






     
    The movement scrubbed up pretty well cosmetically but the amplitude was only 200 degrees dial up and there was around 30s variation over four positions. I tried a different barrel and mainspring from a 6309 that was previously putting out around 230 but it made zero difference. I then went about pressing out the fourth wheel and barrel arbour bushings from the train bridge and replacing them with the bushings from the 6309 movement, and the third wheel bushing was replaced with one from a 6139 (the 3rd wheel bushing from the 6309 was a smaller o/d so not interchangable) but still no difference. At this stage I was getting kind of tired with it - I could have bought a new mainspring and/or complete balance in an attempt to improve the amplitude but it was running again and keeping reasonable time for a 47 year old watch, plus I'd already spent around 4x the time on it than I would on a regular 6105 service, so all that was left was to relume the hands and bezel pip (the dial lume was in good condition so wasn't touched), fit the new crystal and get it cased up. I also fitted the nos crown that was supplied and was glad to see it passed a 60m pressure test - 



     
    If you know your 6105's you'll notice that the hour and minute hands aren't correct and are the same as what you'd find on a 6139-6002, but it appears that Seiko fitted these hands to 6105's when they came in for service. I know that Paul is currently trying to source the correct original hands and when he does then I'm sure I'll see this watch again for them to be fitted, but I'm pretty happy to see how it's turned out regardless.
    If you've got this far then thanks for reading!
