I don't have a gen to show you but it should be plainly obvious at close range the difference between a rep and gen dials. The clarity of the markings and the texture should give it away. Sorry if that wasn't what you were looking for.
I had a Taka crystal in my V3 before I got my V1 and put it in there. No problems with either case. I did it myself so it wasn't a big deal.
I don't know about your rep crystal but there was a huge difference with mine between the clarity of the crystal itself even with the purple AR removed. The stock rep crystal was dirty looking and the Taka is crystal clear in comparison and makes the white markers on the dial look much better. Anyway, what I'm getting at is that you shouldn't take your rep crystal and spend big bucks on AR treatment if it's not a clean and clear crystal.
It's a beautiful watch and enjoy! I wish the movement in mine hadn't given out. It's just been sitting idle for a while now.
Yes, that's the latest and greatest. There is another version which is the same outside but with Asian movement for like half price though. Premium for "Swiss" isn't worth it. Gen co-axial movement is lower anyway. I don't know if Andrew carries that one but you can check around.
Steinhart straps are really nice. I believe I read somewhere Steinhart has their straps made by RIOS in Germany. I just ordered a RIOS padded dark brown buffalo strap for my 3717. I plan to order a German-made deployant (RDH, Axel Jobst, or similar) instead of the buckle if I like the strap.
Out of curiosity, what size buckle is the Top Gun?
If you read up on the little white lies from some dealers, you'll find you are much better off buying an Asian movement watch and having one of the modders add an aftermarket movement. This way you'll know the providence and know what you are actual getting.
That said, I would buy the Asian watch and wear it with pride until there was a problem.
I've read all sorts of shady things going on with "Swiss" movements. Older models, used parts, using clone movements all the while charging premium pricing. Just get the Asian 7750 movement. If you love the watch and want to put a Swiss movement in it, have one of the forum modders put an aftermarket movement in. That way you know what exactly goes into your watch and not some Little White Lie. Probably cost you less anyway.
