Can you make a simple drawing and show where do you cut the crown guards? I am not able to understand where you are removing material.
Unfortunately, i don't have more pictures that focuse on the stock case's crownguard, but the stock case's crownguard opening was uneven and narrow. Therefore, I needed to open up the crownguard by removing some material.

Great result Pom - looks stunning!

Mine is currently out for service, so will hopefully be back soon and pressed into daily service.

I would see if you can work the bezel a bit more, so that you can use a spring washer. Without it, the bezel, whilst 'tight', won't lock out the way it should, or, on the other hand, be able to be depressed and turned easily.

Should be easy to do, if it's turning, so the ID is good, just a little off the thickness. A few minutes on the wet and dry!

The Tudor 2784 movement arrived:







I also did some case work. Firstly, the stock crown/ tube are removed.



Then the case is re-tapped so that it fits gen-spec 7030 triplock tube.



The gen crown and gen-spec 7030 triplock tube are temporarily installed to see if I need to countersink the case. It appears that I don't need to countersink the case.

The next step is to reshape the insides of the crownguards.



I use a dummy athaya crown/tube to check if the opening is wide enough, as I reshape.

I am satisfied with the results.







However, there are still burrs left from reshaping. I use a diamond file to remove the burrs.





Then I use a dremel with green polishing compound to polish the insides of the crownguards.



The insides of the crownguard is now reshaped and polished.

Do you u the 3mm x .35mm tap to retap the tube hole.? I'm looking change my crown to a gen crown also.
Do u use a file or dremel to shape the crownguards.? Love your work.. I seen a lot of your builds and every single one is awesome bro.

Thank you!! .. I agree about the blue snowflake however the Black dial just dresses easier.. something about those vintage snowflake dials black or blue I can't get enough of. :geek::p
Black dial/ bezel is a very classic and timeless look.

If I could have a ghosted bezel insert like yours, it would be perfect. But i don't want to ghost a gen bezel insert, so i will leave it as it is for now.

Thanks. I already tried a super thin dial spacer that I previously modified by sanding/polishing/softening the sides/reducing the internal and external diameters, but it was still quite tight.
Without the bezel washer, the current tightness is ok. The bezel can remain still even if i nudge the bezel.

I will leave the bezel for now. I am going to focus on reshaping the crownguards next!

This post was so educational! Thanks for sharing man, such a great watch you built!

No problem! I am happy to see you that enjoyed it.

You do amazing builds bro.

The gen-spec tube that is used for 703/ 704 crowns is 7030 tube. The 7030 tubes have triplock feature, which basically means having additional gaskets on and inside the tube:

What-is-The-Difference-in-Twinlock-vs-Triplock-2.jpg


You can use genuine 7030 tubes or aftermarket 7030 tubes for gen-spec 703/ 704 crown. You can find them on ebay by searching "7030 tube". Also, 7030 tube only works for 703/ 704 crowns. If you are using replica crowns, then it might not work with these tubes.

Depending on the case and production batch/ tolerance, you might need to countersink/ counterbore the tube hole of your case in order to install a 7030 tube.

Are the bezel from these 2 guys made to gen spec and fit gen crystal and insert.?

The clark bezel fits my gen service insert.
The stock bivintage bezel does not fit my gen service insert.

The clark crystal retainer needed modifying using a dremel to fit my crystal.

But as always, the production batch/ tolerance can change, and different parts can have varying tolerance/ specs, Your mileage may vary.

Do you u the 3mm x .35mm tap to retap the tube hole.? I'm looking change my crown to a gen crown also.
Do u use a file or dremel to shape the crownguards.? Love your work.. I seen a lot of your builds and every single one is awesome bro.

From my experience, all bivintage tudor submariner cases need to be re-tapped in order to install other tubes. I use a M3 x 0.35 tap

Yes, i use a file to reshape the insides of the crownguard

I'd contact them to check but Jensen is Phong's son, long time REP watch/part maker and so I would say 99.9% likely to be GEN-spec.

Thank you bro... I have a mq case and it looks exactly like a bivintage one. With all the same faults also... pretty disappointed in it considering how much it cost.

Thank you for all the tips.. I've checked out all your builds and have had a mq tudor for a while, with all the things that u have modded on your bivintage case being issues in my one. E.g crown, bezel and crownguards. MQ case looks exactly the same as bivintage in my novice eyes. So I'm quite disappointed as the price I payed for MQ, I really expected better. This is my first build I've ever attempted.
So I appreciate all the little tips and information from your builds.

Very interesting that the BV appears identical to the MQ - I too would be disappointed with that as I am guessing the difference in price was "significant", perhaps multiples of BV's price? Any pics? How is the bezel action?

Yes very disappointed.. price was double bivintage. Crystal and bezel were shit and so loose i could pull it off with my fingers.which is why I'm looking for a new bezel that would fit with gen spec.
This is gen spec crystal and the retention ring had to be streched by some tool a watchmaker had. Because when I first attempted it the ring was so tight that it cracked the plexi. Even with the little stretching it's still very tight on the crystal and now the bezel is super tight, not to mention I can't even fit the bezel spring in now. Can't fit this gen service insert without a little bit of glue.
The crown also looks crap, and something else I want to replace with a gen. But I'm not sure if I can fit a gen on the mq tube. I emailed MQ and he said I don't need to change because his crown is already gen like. ( I totally disagree with that). He said his tube can fit gen crown. But he also said his bezel can fit gen insert. So I don't really believe anything he says.
So those are the things I wanna change, and the crownguards are completely wrong for a 79090. Another thing I want to mod, but have not yet got the courage to attempt it. Need to practice of cheap cases first.
Here are a few pic of my Tudor submariner 79090 build.

Is that a bezel gap between 0-5 mins? Sounds very, very disappointing! Sorry to hear! If it's any consolation - the watch does look good, if not completely GEN-like.
