Hi! I’m trying to discover if this dial is an original one or maybe a redial.
The date/month is in portuguese, but that is positive for me (brazilian).
It says Swiss Made at the bottom, but it looks like moisture has affected it, along with the numbers. Also, I have a question about the numbers and whether they’re correct - I’ve seen other examples with the dates all facing outward, not partly outward and partly inward.


Tks!

You ok with this? It looks like an old re-dial. Numbers have been wiped off?

I don’t even think this is an Omega at all. Need movement and inside caseback photos to confirm.

Redial, wrong hands and almost sure the rest is also not what is to be known as a tdmp, hence made-up.


The references for the vintage omega tdmp should be:

2471 (35 mm steel)
2473 (35 mm gold)
2606 (35 mm usually steel with goldcap - thanks @cristos71 )
2485 (gold 37mm)
2486 (steel or goldcap/plaque 37mm)
3944 (square and not round)

None of these references has a case shape like the watch you posted.

2606 is always steel with gold cap

So true and adjusted - didn't took a look at those for quite a while - looks like this

The reference is totally wrong so is the case and the dial is a redial etc.

Stay away from it..

Here some original references:
