The Viet/China cases are pretty shit.
I spent $850AUD on mine through a UK seller, The bezel inserts are just clear acrylic with a thinly painted bezel pattern on the back which starts to flake of/delaminate.
The seller sent me a second insert which also flaked off the moment I touched it. The lugs are pretty bad compared to genuine, and the bezel action is truly woeful.
I build a franken with a NOS Omega dial I paid $1000 for as well as NOS hands from switzerland ($200), NOS center hand (Cousins - $30), NOS movement 562 I had in stock.
I really desperately wish that someone could copy the genuine case 1:1 - but its probably not going to happen as the dials have also dried up and hard to find.
Also found that my rotor doesnt spin at all with the movement in the Vietnamese case. I had a very thin spacer ring that allows for genuine dial to sit in the aftermarket case (the AM dial is a tiny bit larger so it sits well) - the genuine dial is half a mm too small.
I suspect this is the reason, but its a bit annoying as I have to rely on hand winding the watch.
If anyone has any good suggestions would greatly appreciate them!
Attached a pic of my watch below. I also have a Uncle Seiko flat link 20mm bracelet which I quite enjoy but the case has dicky lugs as you will be aware of.

Unsure of the case construction of the viet case. I’ve been trying to find one worth buying for a while.Also found that my rotor doesnt spin at all with the movement in the Vietnamese case.

If the dial seats against the crystals internal compression ring (polished rehaut ) the best option would be machine a new compression ring with a slightly more acute aperture angle therefore reducing the rings ID but maintaining its original height. This of course is considering that the crystal and case is Gen spec construction.
Or machine the internal of the case back for more room.

Little update on the hrudoland case project.
Managed to machine an angle on the back barrel ( caseback seat ) to more resemble the Gen.. I’ll probably go again and get it much closer just need to make some more tooling.
Machined the bezel reducing the bezel teeth thickness to more resemble a 165.024 but this is experimental ill probable leave slightly more tooth height with the final case. Brushed Finish not completed yet.
I had to machine a movement retainer to hold the ETA 2824. Unfortunately the hrudoland case doesn’t come with a tab groove as the original movement is an NH35 with plastic holder. I machined the retainer to also snap fit an omega antimagnetic cover, the centre nipple on the cover comes into enough deflective contact with the caseback once tightened down and provides the perfect pressure on the retainer ring to secure the movement.
I will also increase the gasket groove to take a nice thick gasket and add a Gen omega crown and tube. Machined the caseback graphics off make it blank sterile.
Going to try and use the speedmaster 57 sapphire domed crystal ( 31mm ) but need to check internal dome height for hand clearance and see if the overall dome height looks good enough with the case.
Had to relume the hands and slightly blasted the hands to get a custom satin finish look.
This has been a great budget build under $500 and has a slight fantasy NOS look. Lume is pretty super bright also

Now I am sure i will also make one
This is awesome. Always in awe at the people who bring the machining aspects inLittle update on the hrudoland case project.

I’m thinking of building one of these using the forthcoming updated Helson Sharkmaster 300 with Miyota as a base. What Omega crown should I order?Little update on the hrudoland case project.

It’s just raffles dial, I much prefer the small triangle dial but unfortunately raffles doesn’t sell a ‘no date’ version
Not sure what crown & tube the sharkmaster uses. The size will depend on what omega part will potentially fit. Most newer omega crowns use an internal crown tube thread. Maybe aftermarket ( non gen spec ) options that could work
Yeah I will have to find someone to help machine the caseback - thats the only option I think.
Just weird why they didnt make it gen spec lol. Its not hard surely to measure a genuine dial?
I need access to a lathe, but I'm in a smaller city in Australia that doesn't have much of this specialty equipment.

You don't need to machine the caseback. The laser etching can be sanded away and will leave a brushed finish. Just sand it on a flat surface.
