Dynamic Geneve

Don't touch either of them.

1. The day/date one is correct. However, the marks on the dial are not a sign of authenticity. They are a sign of bad care or bad servicing. Both possibilities are a red flag. To me it looks like oil has been dropped onto the dial during a service. Stay away from it - if the movement is bad then you can easily spend more than the value of the watch in trying to sort it out.

2. Run. Now. That movement was never originally in that watch. The case should have a radial brushed finish. Instead, its been polished to death and it kills the watch. It's an expensive mess & the salvageable parts have relatively little intrinsic value.

Desmond wrote a great article that is well worth studying if you like these watches. There's a great table at the back that explains the features and movements of each reference: https://omegaforums.net/attachments/omega-geneve-dynamic-i-pdf.459/

If you have any questions, just post them on the forum. Good luck !

You dodged a bullet there. At £190 it could still be said to be overpriced...

It's a terrible redial, wrong fonts, incorrect shade of blue, inaccurate markers. The second hand is wrong, the hour/minute hands need repainting, the case is poor, the case back is overpolished. It's a car crash of yuck.

If you like the racing dial pattern, then this is the sort of thing to aim for:



This is a pic I just grabbed off a Google search. There are colour variations & I like the silver ones. Beware of any in outlandish colours, especially from SE Asia, as most of them are redials.

It should be a cal 601 manual wind & the model no. you identified. If it's a cal 552 automatic wind model then it'd typically say "Automatic" on the dial.

Originally it would have come on either a SS bracelet or a Corfam strap. The Corfam was a new synthetic material at the time, but they disintegrated over time so it's unusual to find any intact now. Omega started making replacement straps in leather in the early 70s because of this.

The aftermarket replacements available now are variable in materials and quality and cost £15-30. I like the suede ones but they're aftermarket and sometimes they're cut too thick to fit under the screw ring, so you take a bit of a chance they might not be useable.

Proper vintage leather straps can sometimes be found, although they can cost in the £70-100 range depending on condition.

SS bracelets are also easy to find in the aftermarket. Personally I'm not so keen on paying the £80+ that some sellers want for their CAD copies, especially as Omega vintage ones can be had for that type of money.

I've also discovered that the original SS bracelets are not always interchangeable across different watches - fairly often they don't quite fit properly/easily on other Dynamics. Whether that's due to machining tolerances changing very slightly across the life of the models, variances in different case batches/suppliers, or just subtle changes caused by wear, I don't know.

Omega still sells straps, buckles, and the bracelets for these. The straps are pretty reasonably priced (going from memory of the last one I bought), but a new bracelet will set you back several hundred...

When you do get the watch open you are likely to see as many as 4 reference numbers inside as this case was used with both manual and auto versions, with and without date.
