  1. I got this Bulova Oceanographer for a good price several month ago only to find out that the movement was incomplete . Actually , I didn't even know what the proper movement for it was supposed to be . After some research and inquiries on the Bulova forum I decided that the Automatic movement 11ANACB was the likely contender , so after a few failed attempts to at securing the missing parts with great help from my buddy and fellow forum member , ramrod , I finally got this puppy running again . A nice looking watch in the flesh even if my pics don't do it justice .

  2. Made in Croydon circa 1938, a lovely example of a pin pallet movement. Sadly I sacrificed two hairsprings to achieve the geometry I was looking for. Very pleased with the accuracy given its age. I’d love to put it on a timegrapher to check the beat error. Sent from my iPhone using Tapatalk

  3. Smooth side outside I think. Look for the tsunami logo, that should be showing when worn, not the Z22, that should be inside.

  5. I think the fault has been eliminated. The lever that Oldhippy suspected was the fault. It had two faults the, first was the flag was catching the warning pin because it had a very rough surface, secondly the lever was bent outwards so it was catching the chiming cam (see pic). I have had it on test and it chiming in the correct sequence for the 1/4, 1/2, 3/4 & hour. Just need to re-aasemble when time (family issue)

  6. I didn't oil the pallet stones. You should a very tiny drop on the pallet stones. if your not comfortable with this then a tiny spot on a few teeth of the escapement wheel. Be extremely careful. I do not recommend this way.

  7. It’s tricky. If I remember correctly, magnetism intensity follows a cube rule with respect to distance, so it suddenly drops off as you move away. So you’d hardly want to distance it at all. The problem with this thing is that the field is so strong that you literally struggle to pull watches or tweezers off the thing. I think the better option for 240V would either be a resistor to halve the intensity, or better than that, a rheostat to ramp down the intensity.

  8. If you demagnetize first, how do you find the calendar and detent springs on the floor?

  9. Well that's disappointing. You are best to focus around the escapement. Check the hairspring carefully. are the coils touching at all? - it is in the index? take the balance out - is the spring flat? check the balance roller - is the ruby pin loose? is the roller loose on the balance staff? Check the pallets - is the guard pin loose? Are the pallets secure on the pallet arbor? Check the balance jewels - end shake and side shake. Has the balance got timing screws on the rim? Are these touching? Is the balance wheel true? Is the balance wheel touching the pallet cock in certain positions? On the timing machine do you get this reading both dial up and dial down? and how about pendant down?, pendant up? Check the hairspring point of attachment to the hairspring collet - is it loose? What about the hairspring stud screw - is it tight? I hope I didn't miss anything out :)
