Tudor BB eta/ZF: Some cheap improvements for everyone

Hi guys,

Today I want to show you some cheap mods for a more gen like look. My object is a Tudor BBB made by ZF with rose logo.

Let‘s start with my crystal mod. The edge of the rep crystal is not clear but matte. So you might be missing some optical effects the gen is showing under certain angles. I decided to polish the crystal edge with diamond compound. Here are some pics of this process:

Fitting new gasket:

Abrasives:

Look and feel:

Next I polished up the rehaut for a bit more shine:

Polishing utilities:

After that I modified the A2824 for only 2 setting steps because there is no date. But be aware you have to change the whole keyless work for eta parts. Changing only this setting lever does not fit to the asia movement!

Unfortunately ZF forgot to put white base color on the underside of the hand‘s lume. You might do this to make the lume a bit stronger and brighter with some acrylic paint:

My bezel insert got scratched so I replaced it with a HR item. But HR‘s insert has got a really shitty pearl with weak lume and a scratched rim. So I had to drill out the lume and repolish the rim. After that the pearl has been relumed step by step with white base color, lume and an epoxy cover:

Gen pearl for comparison:

After all I performed several little things on the bracelet and clasp. It‘s important to pay attention to all the little parts and details. For example I deburred and repolished every screw. The inner shield logo of the clasp has been polished, too. After that you won‘t notice those awful stamping marks.

Here are some impressions:

Rough surface made by ZF. Not very much to improve here. Rebrushed and deburred:

No more protruding springbars at the clasp:

Final satin finish with Gerryflex abrasive medium:

Overall a gorgeous watch!

Look at those nice optical effects on the crystal edge. You can clearly see the dial markers reflecting in the crystal edge area!

Lume ist o. k. but does not last for many hours.

I hope you enjoy this little workout. If you have got any questions feel free to ask!

Best regards

Very nice! Just awaiting on my BB Black to arrive. Might give this a shot.

Quick question, how is the dial print? Are the markers and text raised or is it flat paint?

Dial print is raised but not very much. A HR dial ist better. It has got better 3D print and better rose loge. Texture is a bit grainier, too. But it is expensive and has got some disadvantages: Lume is weak. The indizies don‘t follow the dial‘s domed contours.
So the best solution would be HR‘s dial with ZF‘s markers.
I decided here to stay with ZF‘s dial.

Got one incoming, it’s been a long wait for it lol. Looks like a really nice watch out the box but might be tempted to tackle some of these myself after a few months wear. Thanks for sharing man.

WOW, really great work!
Perhaps you can tell me what kind of rivet pin I need to fix the broken one on my buckle that would be nice.
I don't know if its 1mm thick and 10mm long or even smaller.

You can easily repair this. Let me have a look tomorrow into my parts box. There is a set containing these pins you need. It is sold by Cousins.UK. Will search for it tomorrow and show you the box and Partnumber. Was not really expensive.

Same as the OP mate. Was a swithering between that and the newest version but it’s the bracelet on the older I prefer (no rivets), the flaws with the rose etc I can live with. IMO it looks like a great watch and I can’t wait to get my hands on it. What about yourself?

Good choice man! I was in 2 minds but I went with the new bb black shield from Sead.

"Patiently" waiting on its arrival...

I’ve been patiently waiting on mine arriving from Sead too! Nearly climbing the walls lol, can’t wait to get my hands on it though.

Nice! The mod on the crystal edge really made a difference! The crystal edge is the only thing that bugs me on my rep Ranger (plus a noisy rotor) and my BB Blue (plus the slightly wrong color on the blue bezel).

HR‘s bezel inser has got a better blue color. The rotor can be lubricated with a very very small amount of oil. I did this on mine and it‘s an improvement.
Tomorrow I will take the BB to work and demagnetize it. After that we will see what the movement accuracy tells.

I have the same ZF BB Blue, but your mods have definitely taken it to the next level. Awesome writeup! Thanks for sharing all the details and pictures. I have followed this thread for future reference. I'm sure it will be a big help.

This is awesome work. First time I've seen someone polish the frosted edges of a sapphire crystal, a trick I am now thinking of attempting on several of my watches.


What is your opinion of the bergeon lume kit?
