Bulova accutron servicing

Recommended Posts

Hi all.. I recently purchased the above watch with 221 movement for my daughter. Everything works, but as expected it runs fast. Does anyone know of anyone in the UK that can sort this out? It's a lovely, clean example that should be worn (if it can tell the time) 

Thanks in advance

HI, just a couple of thoughts off the top..

How fast is it running? If a few seconds a day, then you will able to adjust with the tiny tabs where the magnets almost meet (they rotate). If it is several minutes fast then it may be 'indexing'. This means that I assume you have placed a 1.5 volt battery in there and I think these movements were meant to use the 1.35 volt batteries (mercury) that are no longer available. I have had this problem from time to time. I also believe you can obtain some kind of insert to manage the excess voltage. I also recall that if the watch is in adjustment the effect settles down after a day or two of operation.

I'm also pretty sure there is a lot of forum info on this on the web on these watches and I'm not saying my approach was the best fix either as there are some that say it is possible to damage the coils with the excessive battery voltage, but this was not my experience.

To perform any adjustments on the pawl or detent you will likely need a microscope or very powerful magnification.

Go well.

    i have an accutron meter (looks much like a volt ohm meter)   and a bunch  of their repair books. they didn't help much.  buying a new mvmt.,  was the easy  repair.  when they went out of production,   the collectors bought most of the parts.  vin

Yes, I believe that is so...I think (again from memory) the one above is the 2210 movement and fairly common still - or at least, last time I looked. They are interesting to work on and the main faults are the coils going open circuit. Another issue I found was that where plate meets a contact requiring cleaning...once done you are frequently rewarded with a satisfying hum.

Also consider if at first it does not start on its own, give it a sharp flick with your index finger...Agree that reading the manuals first is always a good start.

Cheers

    • If you've used properly fitting hollow ground blades for larger fasteners you know they can handle a lot more torque than a regular screw driver without damage fasteners.   The difference is so pronounced you just should not work on antique machinery/equipment with slotted fasteners without using hollow ground blades or you will botch up the fasteners. However, relative to the current debate, two things occur to me 1)  To get the performance noted above, the bit has be a very good fit in the slot.  My set has I think 85 or 90 pieces.  Without that selection and ability to find a perfect fit, their advantage pretty much disappears.    Is a watchmaker going to have a similar selection to ensure that perfect fit and futz about constantly checking microscopic differences in fit?  2) Performance is superior, but the metric is torque handling ability.  Does this even matter in watching making?   My limited experience suggest no.  otoh, if you are  regularly damaging heads of screws with taper blades than yeah, figure out how to get an assortment of hollow ground bits that work for you....but otherwise, why worry about it?   imo there is no debate to be had on what is superior, the debate is simply whether it matters given the torques involved. A young guy I know worked for Roger Smith for few years (talk about a learning opportunity!).....I'm curious on he was taught

    • yes sir, forgot to mention "cone shape",  the  ajuster is a good thing,  i have over tightened the staff in the past.  this one is "floating" almost 1/16 inch !   i decided not to tighten the staff.  it's back together and keeping good time. Thanks,  vin
