A very distinct looking watch, this Bulova chronograph! Rob sent it in for a service, as it sometimes stops.
Performance isn’t too bad considering the watch hasn’t seen a service for a long time.
What is marked as a Bulova 14EFAD is of course a Buren chronograph movement with a micro rotor. I love these – great movements, and the micro rotor is just a super construction.
That dial is just great.
The bezel is glued onto the case. Not quite sure that this is original 😉
I will fit a new crystal as the old one is pretty scratched.
The pushers are getting a good clean as well.
The movement does not only have an automatic winder, but also a date display.
The chronograph in all its beauty.
Time to take it apart.
Slowly but surely, I work my way through it.
Getting closer …
And the chronograph bridge is off, and we can now see the base movement. One of the great features of this movement is the intermediate winding wheel, which sits between two big round jewels.
The gear train.
The old mainpring in its barrel. You can’t get new mainsprings (or any parts, really) for this movement, so I will reuse the old one.
The bottom plate with the date mechanism.
A quite unusual clutch construction. When you set the time, wheel that drives the canon pinion can deform, so that the teeth can jump. If that’s elegant or not is another question 😉
Everything goes into the cleaning machine.
The mainspring greased and back in the barrel.
I put the balance jewels back into place.
In order to be able to put the gear train in, I have to put the bridge for the setting wheels back in.
Now I can put the gear train in. Only the escape wheel is jewelled, everything else runs in steel bushes.
Here you can see the steel bushes of the gear train.
Not fully wound, this is looking good for a first adjustment.
With the gear train beating, I now put in the micro rotor and its gears.
The winding gears back in place. All the pivots of the winding gear run in steel bushes as well.
I can now put the chronograph base plate back on.
And I start on the chronograph.
The chronograph put back together and adjusted.
Now I turn the movement over and put together the bottom plate.
And I’m ready for the dial and hands.
Looking good already!
Cased with a new crystal.And with the bracelet. Unusual, great looking watch!
