Omega Seamaster (14701.1.SC)

Recommended Posts

Hello everybody, 

Recently I got my hands on this nice looking (IMHO) thing. And I think I want to replace the glass, or at least buy a new one for comparison.  

Problem I have is that, when I look by the model number, I find PX5001 or PX5140, but both are with a golden ring. 

Of course I could just measure the crystal and look it up in the catalog by size and get an ATC, XAC or something glass. But I was wondering could I find an original piece? 


Does any one know the chrome version part number? 


P.S. Also, is this some what rare, the blue dial? I couldn't find this exact model in the web.


Thank you in advance!

this you mean?

Yes that's perfect then I guess had to decipher how the numbers are laid out. Plus it was helpful to have the movement number so that I know if I have the right case.

Oh and you might want to look carefully at your photograph these studs screw and maybe they hairspring regulating screw look like rust perhaps? Even they hairspring looks a little but it could just be the photograph does it doesn't look like any other rust anywhere it just looks suspicious

Then the problem with omega case numbers are there not specific.Is actually six different case types another is made out of gold of various colors and for them have the correct movement.

As usual with omega there will be confusion there is three crystals. Looks like the first one does not have a magnifying glass and the other two Have magnifying glasses and there must be some difference but it doesn't actually explain what the difference is.

@JohnR725 I think the picture overdramatizes a bit the reality. I have serviced the movement and I think I runs nice now. 


Glass: Thank you for the reference info! I think I will try to find both(with and w/o magnification). As I said, I tried searching the web for this exact model with a blue dial and couldn't find anything, and eventually see which one fits/looks better.

blue dial

Oh and when I was there I did take a quick look at the dials and I did not see a blue dial. But that doesn't necessarily mean anything because you have a blue dial. As I said you find their case numbers were referred to a whole bunch of different cases made out of different materials raise grades a gold usually are goals and stainless and then occasionally the crystals might even be different for the different case is not just the weather it has a gold ring or whatever I've seen sometimes are sized a little different may be because the gold was a little different hardness or something I'm not sure why. So simplistically anything older for Omega you're going to get variations and because Omega doesn't like to sell parts to anyone in the universe finding vintage parts becomes more and more difficult as the original ones are slowly purchased and there's nothing left

    • Sometimes you are the windshield! I have been anticipating this lot coming in. No pictures of the movement, but the dial looked good. When it arrived, it was better that I could have imagined! Only missing the seconds  hand, winding stem and crown. But everything else original. I opened the back and was not disappointed...ETA 1256. According the Ranftt, first ETA automatic (Etarotor). As I gazed in wide wonder, I used a piece of pegwood to move the rotor from covering the balance. It was beating and strong!! It stopped shortly after but got it to go again.  Hopefully a servicing will be all this needs...
    • I stumbled upon a really nice technical guide that actually shows the order that parts are reinstalled into the movement.  As a new comer to this hobby, this is a huge benefit to have.  See the PDF for the ETA movement below for what I mean and look on pp's 6 & 7 in the box where it says "Assembling ...." Better Version_Hamilton 742_Dads_ORCO_Watch_936_ETA 963.111, 963.121.pdf Now, with this Seiko technical guide, I don't see anything labeled as such.  Is there a way to read the drawing that will tell me the same thing?  Is it just follow the circled numbers?  I see in the legend on p 2 it says something like that, but just wanted to be certain.

    • I think it would be incredibly cool to lathe your own parts.  Unfortunately, I have yet to see one that is inexpensive.
    • Hi Richard  No problem ,  I think as far as lacquer is concerned  best get the ones recommended like Horolacq (cousins). and yes you will need to peg the holes to remove any build up.
