I have just joined the forum and this is my first post. A quick introduction: I have always enjoyed my watches and had a range of Rolex, IWC, JLC etc over the years but all were bought new. I still have a Submariner, an IWC big pilot and a 1950 Panerai. However as I have got older, I find myself being drawn to smaller, more understated, vintage watches such as Zenith but particularly Omegas. I am starting completely from square one and know very little about Omega, so have ordered the book 'a journey through time' which should arrive in a few weeks but have been trying to learn as much as I can in the meantime. I am drawn to some of the early oversized watches (37-38 mm), such as the one in my Avitar (I'm 6' 2" and a 33 mm case just looks odd) and also some of the 1960/1970 steel watches, again as the case sizes increase to 37, 38 or 39 mm. I would like to be able to wear the watches, not to keep them in a box, although maybe for just a few weeks at a time. I have bought the watch below, mainly because I like the understated and aged dial but really to learn more about this type of watch and Omega in general. It obviously needs work so I also wanted to use this to learn more about who is best to take it to, what work would be appropriate etc. I have already made mistakes with this watch but in Summary I can see that: The rotor is binding on the case The dial seems to have dropped a little in the case as the 'swiss made' wording at the bottom is not level The day has drooped in the window The crown is a bit 'sloppy' There is a chunk of thread missing from the case, see last image Next to where the thread is missing, the case is thin and sharp; is this where the original metal strap would have worn the case? However it keeps good time, it works, the case is not too bad, I like the look of it, it sits well on my wrist and it was cheap. Firstly, can someone help me to define exactly what it is? It is obviously a Seamaster and it was sold to me as a 1969 but I think it is 1970. Can I access the full list of Omega serial numbers on line to date it properly (I have found some rough groupings of numbers and dates)? Is 751 the caliber and the case number 168.034? So if I was to call a watch maker would I just say that it was a 1970 Seamaster with a 752 caliber or would they need the case number as well? Does the fact that it is a Chronometer make it any more complicated? I would like to be able to wear it and get the watch in good shape without detracting from the value (which in its self is limited). So who would be the best person to do the work for this type of watch and also be happy to have a chat with me about the findings, the options etc., so I can learn something in the process? I have so many questions but just for the moment can anyone see any more obvious howlers? Does at least the case, back, dial and movement all appear to be original and matching? Have the hands or day / date been repainted? Thanks in advance.
