Oddly it's always annoyed me how the red black bay has creamy lume on dial and hands an a perfectly white pearl. It could do with being the other way around.
You won't find one with a genuine ETA movement in from any seller. The ones you see advertised are lies. You are better getting one with an Asian clone of 7753 and sourcing a genuine ETA 7753 separately and having it installed.
One thing to keep in mind is the hand sizes between Swiss and Asian 775X movements are slightly different so might need some tweaking to work. Unless you can source some gen hands.
I think A7750 gets a kicking when it doesn't deserve it. In the standard configuration they are reasonably reliable in my experience. A service will help this.
I have bought lots of gen TAG parts from a seller on eBay based in Malaysia.
He can be a bit slow to reply to messages at time but is a great guy. Or you can get a crown from cousins, but it is difficult to figure out what is correct.
Send a picture of your crown to the guy on ebay.
My franken says hi.
Not to be rude but I wouldn't want to wear a used leather strap. A new clean one would be much better. Even if it's not croc.
If it's gen a new tag one will set it off. It's worth the cash.
It depends on what dial. There are considered 5 dial variations from different time periods and they go for varying amounts of money. The 5th gen superlumed one being the cheapest.
