If I'll find one good Pro Unter dial,
I'll take one standard WM9 ,
I'll dismount it and I'll get PVD on.
Some numbers and letters on the caseback and all is done!
IMO:
I prefer to spent my money for one correct AP sec @12 gen alike.
If I'll have problems, the service stores are on the market.
For this reason I nether bought the completely wrong sec @9 APRO.................
Are you sure are you looking for perfect?
Or ,are you looking for cheaper?
There are around 80$ sub too.............
Ps:
If you look for perfect , get a look at WM9 16610 Z too.
