When Did Rolex Start Using Sapphire Crystals
I have a Submariner 1980 vintage and I thought it had a Sapphire crystal. But I read that Rolex did not start using Sapphire crystal until 1990. Is this true?

Am I the only one who thinks that something just does not look right here ?..
I know we are talking about some aspects of a dial that over years can be found across several manufactures (hour markers, hands, 5 seconds markers, dial texture etc.)To me it is just too many similar elements between two watches that came out within one year from each other.I am somewhat surprised. I met Martin Braun personally and I always thought ofhim as an innovator. "To me" - the above borderlines with flat-out copying.

Is there an easy way to spot a Citizen"fake"?
Hello Everyone!I am very interested in purchasing a Citizen Eco Drive Calibre 2100 watch. I have seen a few on ebay that are display models that include the box but no papers or tags.I compared the photo of the model on ebay with the same model photo on the Citizen website, and on the ebay model there is one word missing from the dial that is on the Citizens website photo.I emailed the ebay seller and they assured me they are indeed authentic Citizen watches, but they are display pieces. He said they have the serial numbers on the case backs.My question........Is there an easy way to spot fake or reproduction Citizen watches?Thank you very much for any help or comments you care to share.

INCOMING: 5712/1A + Thoughts on 5712 vs 5711
After a lot of effort and some luck, I received my new 5712/1A from my AD today!!!I had been going back and forth between getting a 5711 or a 5712 (both in steel/blue dial), but went for the 5712 after agonizing over this decision for a long time.By way of background, I have a good friend who already has a 5711 in steel and I would constantly bother him to try it on, inspect it, or just stare at him wearing it to get a feel for it in every light condition. In the end, my thoughts were that it is a gorgeous watch and sublime, but in indoor lighting it takes on a vintage look that I wasn't crazy about. In short, it needed the dial to be alive reflecting light to be in its full glory. Today, after wearing my 5712 for several hours and looking at in in a number of lighting conditions, a few things stuck out to me that I wasn't expecting. First, I actually PREFER the 5712 dial in outdoor lighting because although there is less open space on the dial for the light to play versus the 5711, th

First time buyer
I'd like your thoughts on my experience (so far). Let me start by saying I do not consider myself a collector and have never before today spent over $500 on a watch.I really hope I'm not getting screwed. I just purchased my first Rolex today. A Oyster Perpetual 36mm with a Red Grape dial. After doing a lot of research online for sellers with positive ratings I came across a company called Avi & Co New York. They are a seller on Crono24 with great reviews and have excellent reviews across Yelp. They also have a physical store in New York.As I wait for my watch to be shipped and delivered I am having some buyers remorse anxiety of buying from an unauthorized dealer. The watch sales retail from and authorized dealer for $5,400.00 but Avi & Co sold it for $4,399.00 for credit card or $4,269.00 tax free with shipping included (Brand New, never worn, manufacturer plastic still attached. The seller contacted me today and confirmed he received my wire payment and got my shipping inform
