Can anyone recommend an Omega AD
Can anyone recommend an Omega AD that could possible get me a 3523.80? Ive been looking now for a couple of months with no luck.. It is a discontinued model but I figured that some AD's might have one still in their inventory or they might have bought one as a trade-in.Thanks

5270R. I'm so very weak
Well I love the new 5270 Rejoiced when they lost the chinI actually really liked the series one WG but never pulled the trigger on one used. So I fully expected to buy the blue one but have always struggled to read the time on it. I saw the 5270R and it blew me awayI'm loving it. The warmth of the dial and case and incredible legibility was stunning.

Help with 5146P Purchase!
Hello,I'm a long time lurker and a relatively new member here on TRF! I've made my way over to the Patek Discussion Forum a couple weeks ago and have been wanting a Patek since then . I'm currently in Seoul, South Korea visiting my parents and stumbled across a BNIB 5146 Platinum at a local vintage watch market for around $56,000 USD at today's exchange rates. It seems like a good deal considering the watch's MSRP is $68,700 USD, right? I'm an extreme newb to watches, especially Pateks and would love any advice or opinion you guys could give me. What should I be looking for/asking? I'm not worried about the authenticity of the watch as the dealer is a very established (~30 years) specializing in Pateks. Thanks for your help!

Possible Day Date 40 dial change?
Hi, was wondering if Rolex still allows dial changes on Day Dates? Did it a few years ago on a 36mm Day Date through the AD to them. Now I am thinking about a change in my rose 40mm. Please let me know if anyone has done it fairly recently in the U.S.. thank you!EricE
