There are a few guys on RWI who do case work so you might read up on RWI and see who's who.
I learned how to do much of the case work on my own but it ain't easy and if you make a mistake, the case may be ruined or ugly as a wet rat.
In reality, you have three options:
1...Learn to do it yourself.
2...Find $omeone to do what you want done.
3...Buy the best example you can find at your price and live with it.
I used to be an 'option 1 guy' but burned out/wised up and am now an 'option 3 guy'.
I will qualify that statement by saying my expectations are probably lower than many/most RWG members because I came to the conclusion a long time ago that 95% of people you know or come in contact with cannot tell a $200 replica from a $3000 replica.
The people you know will say "NIce replica" after you tell them what it is and maybe ask a few questions about it. They will assume any watch you are wearing is a replica thereafter.
The people you do not know might comment on the watch and if you tell them it is a replica, most of them will mentally or verbally label you as a scam artist of the lowest order. If you tell them "It is genuine" they will figure it is a replica anyway and go on about their business. A few may ask "How can you tell?" and others might ask "Where can I get one?" I just say "Dunno, I got it from a friend"...after all, I see this 'friend' in the mirror every day so I am not lying.
