I bought my first Omega watch a week ago for 20€. It is a Steel Ladymatic Seamaster and I have tried to find more information about it, model and age. I have found a few that looks similar to mine but they have a second hand. Can it be missing in my watch? The watch is working fine.

 

The information you need is inside the case back and the serial number on the movement. It may be missing or it may not have one. You really need to see inside to know for sure.

 

That’s a lovely grab for $20- love the big seahorse on the back. First question, are you a lady or is this as a gift for a lady?
As @efauser said, the data to accurately tell the time period and model are inside- but without a watchmakers knife (and the skill to not damage the back or yourself) you won’t have access to it.
I can guess based on style that it’s probably around 1959-63, not seeing the “T” along side the Swiss made at the bottom (a sharper pic would help) which would put it pre-Tritium lume.
Getting this to a qualified watchmaker would be my first order of business for a proper cleaning and oiling, they can tell you the case and serial numbers to help date it.

Also, after service- throw it on a burgundy or brown crocodile strap and it will be sharp as hell.

 

Thank you! My husband found it in a vintage shop, and I bought it to myself. I will take it to a watchmaker to check it.

 

Let us know where in the world you are and someone can refer you to a qalified watchmaker who specializes in vintage pieces. The key is tyou don’t want them to replace any of the cosmetic parts (hands, dial etc- unless it is missing the second hand which they can source an original) or put it to a polishing wheel (polishing the stainless case will soften the sharpness of the case like a lozenge and take away the light patina that gives it character) . Just a good cleaning and a crystal polish and it will gleam like a gem. The cost of service will run about 10x the price you paid for it, but well worth it as you can’t touch a quality watch for anywhere near the total investment and it will last you a lifetime as long as you keep it away from water and keep it serviced every 5-10 years

 

And just to share- a few vintage Omega’s that my
Lady wears- watches are like chips, you can’t have just one.

 

I live in Sweden, not far from Gothenburg.

 

Wow!
