IMO, I think it’s a better idea to just use the 4130 clone movement. Functions just like the gen movement, and reduces the overall costs. Plus the watch still wouldnt be gen just because you got every part gen. Just my opinion tho.
Don't know what you mean by this. Gen? If every part on it is GEN, it is a GEN. It isn't a rolex built one but it is 100% genuine so it is a GEN. The word Gen is a joke. It is something only people with fake parts say. I know on Ebay when someone puts GEN on the sale it is most likely not real.
If you look back on my post, I have built complete, 116710LN and 16700 all rolex and Rolex inspected them and registered them. One under me and another under a ex member from here. Also I sold a 100% Rolex 116610LV and a 16613LB and a 16800. All 100% Rolex. All built by me. I just brought a 16620 from a buddies auction house. I posted it here. It had a bunch of fake parts on it. I just brought it back to 100% Rolex and sold it back to him. Rolex will have no issue with it when they look at it now.
People, as was I, think Rolex is a lot smarter than we give them credit for. Example. The 16700 that I built started with a case. I knew nothing about gmt's. I got a real 16710 dial and hands a new 3186 (which didnt really fit the case) and built a 16710. Then I found out about the 3175 movement and found it is almost identical to a 3135 minus 6 parts. Ordered the parts and built a 3135 up to a 3175. I though that rolex would had check the serial number on the 3175 and found it was a 3135 built to a 3175. No. The guy who brought it from me took it to Rolex in CT and they told him it was in perfect order, gave him an evaluation on the watch and recommended that the hands be replaced due to a scratch.
My 116710LN was built by me and I met up with a member from here to get his band evaluated at Rolex in NYC. He needed a real 116710 head. I took my real band off and took the head and put his band on it and paid the evaluation price and they passed it and registered the serial number under me.
So a rolex that is 100% is a real rolex. They don't keep a lot of records at Rolex. I have ran a lot of watch serial numbers. A good 85% of them have zero service history. There are a lot of non rolex watch makers that service rolex, and no one but us here at RWI really care.
