Hi anyone and thanks to entered this thread

I’m thinking at a new project that involves the ST19 movement and the vintage Daytona vj72 case.

Many vintage enthusiasts would like to have a more possible gen-like vintage Daytona but without spending the 6/7k $ to have a good high end build.

I thought about a way to have really aesthetically medium/high build gen-like vintage Daytona from a minimum budget of 1000$:

500/600$ for a mid quality viet VJ72-specs complete case

400/500$ for a good viet dial

Obviously there are very high quality VJ72 full cases that costs more than 2000$ and even dials that cost around 1000$… exactly as there are low quality VJ72 full cases at 260$ (like the one from AliExpress) and low quality dials for 150$ from some sellers.

But the whole point of this, the real deal, is to fit the ST19 movement in the VJ72 case, and here the things get tough

AWe know that VJ72 is 29.5 mm x 6.25mm and ST19 is a bit larger so for the fit we will need to enlarge the case or reduce the movement, or even both together, but wait…

We can’t ruin a VJ72 case working on it…..

Then, I started searching on the web if someone have ever tried to do this before and I found a brave man who did exactly this, reshaped the ST19 to a smaller diameter, then applied a little distancer between the glass and the movement to make the height match too and let the stem and the pushers works!

ST19 movement can be find at 80$ or 100.

Now conclusions:

We can have a Vintage Viet Daytona powered with a ST19 at less than half the price

If we want very good viet parts that will be around 1600$ completely with movement too

For lower budgets we can have the 260 case (AliExpress - not engraved) and the 150 dial (yuki) and with another 80$ the movement. In this case we need st19 hands too that can be found on eBay as alpha chronograph hands for 10$ for a total of 500$!!!

So… it’s a real deal! Only have to decide the budget to spend!

I will continue another time with the technical parts :D

ARE YOU INTERESTED??? ;) thanks 😊

Keen to hear more about it!
Out of curiosity, do we go with st19 hands because they're affordable or is it that the valjoux hands we see from viet dealers do not fit the st19 movement?

St19 hands is different, so if we fit the st19 on the vj72 case, we will need the st19 hands
I used some sets of those today for a full custom build with pn reverse panda dial :p



These sets are of good quality and have tiny hands for chrono subdials

I had a 6238/6240 build by @tripdog with the St19 movement on a cartel base. Turned out phantastic esp. The case work he did, but the subdial at 6 Was frozen due to using the St19. Would'nt that be the problem with an Vj72 case, too ?

Yes but I fear that pushers are not gen specifics like the Vietnam one, but are like the st19 one, aren’t them?
Ask Milk, not me, i dont make this case, cannot give specifics, my guess is as you said, not gen specific, afterall, the gen watch construction is suites for vj727, not st19, must be different
