Hamilton Khaki Automatic Dive Watch Purchase Concern
AllI am new to this forum and after reading some of the information on here it sounds like im in goods regarding Hamilton concerns. I am extremely interested in the Hamilton Khaki Automatic, Serial#77515153 but have been unable to locate it as Hamilton no longer makes. Ive found a few places online that sell that have told me they are out of stock, but also in this online search have found several fake/replica pieces that leads me to wonder if any site is legit? Anyway, the watch is currently being auctioned on ebay and my concern is that it is not authentic. Researching online I found the same model to have a diferent looking gear setup through the see through back so am skeptical but desperate for this piece. Any suggestions as to whether or not it is an authentic would be much appreciated, and if you know anyone selling this piece let me. Great to join this forum! Thanks[MODERATOR'S EDIT: Non sponsor link has been removed; explanatory PM sent]

Which citizen model is this?
I saw a Citizen watch that I wanted to buy from ebay, but it doesn't give much information on the clock. I asked the seller for some more pictures so that I could look up some info but I haven't gotten an answer yet so I thought I would ask here.can anyone tell me what model the watch in the picture is?

First Post + First Watch
I am 43 years old and I never wore watches. I decided to embark on a journey to seek out the perfect watch for me. I started with various watches and I ended up shortlisting it to two. The Rolex Daytona and the Omega Speedmaster Professional. I decided on the Omega for various reasons: NASA History, Classic Chronograph and I loved the presentation box. I passed on the Rolex because the cost was almost 3x and the availability was limited (long wait-list). The decision then was which version of the Speedmaster Professional to get. So I looked at both of them online in detail. Read all the reviews. I also went to an Omega Authorized Dealer to see both up close and personal. At 6'1 190 LBS and 6.75 wrist, I was concerned the watch would be slightly too big. After seeing them and trying them, by initial thought was true, the solid back with the hesalite crystal was the only choice for me.The last part was, where to buy it and how much should I spend. I narrowed it down to CH Je

Lume Question needing answering
HiWas just wondering whether somemone might be able to tell me if the lume on my Omega Seamaster is Luminova or Tritium. I have had the watch from new and was bought in December 1999.Thank You.....

Some help? 533, 531, 351
Hey guys,Its been a while since posting but the watch bug has bitten again. So tried to stay away from the Pam's. Checked a Rolex GMT Master II but it just doesn't suit me for some reason, I love seeing them on others but not me. AP 15400... strange looking on my wrist but might be because I have seen the 15300 in the wild and that is a better size/proportion.I used to like the IWC Spitfire 3878 but after trying on a 1950's Luminor case... I really want one.So I am torn between the 531 and the 533. The 351 is kind of a semi distant 3rd, mainly because I find the titanium too light for a PAM :)The tobacco dial and gold hands are lovely though.So the 531 has me at 24 hr traditional GMT, like my 297, however it is quite similar to my 297....The 533 has that lovely 10 day reserve and I have really enjoyed the 7days the my IWC Portuguese gives me. I also would have loved to have the 270 back when I got my 297, but funds were a different situation back then.I do not really plan on selling t
