Ref 7188. Cal 711

luxtime · Oct 12, 2024

I bought this watch from a lady who has it from her father, without knowing something about the timepiece. Nothing on the internet. It tested positive for gold. But I'm not sure if it's white gold or yellow gold Rhodium plated. Why anyone will plate yellow gold???
I'm not sure if it's original.

Do anybody knows something about this watch?

Ref 7188 with Cal. 711.

I was thinking to go to an Omega shop.

Thank you in advance.

It's a genuine Omega, although not marked this model was also sold as a De Ville.
The case was made for Omega by Serva S.A. of La Chaux-De-Fonds.
The case may be Rhodium plated (see yellow mark on the case opposite the crown).
Movement looks very dirty and may be missing a case clamp and screw.
Rotor bearing/bushing is worn allowing the rotor to wobble and touch the caseback.
It needs to be serviced.
An independent watchmaker with an Omage parts account would be a better choice rather than sending it to an Omega service centre.

Thank you for your fast answer.
Did Omega Rhodium plated any other gold models?
The first watchmaker I brought it to, was thinking that it's a Fake. Until he opened the case. He was amazed that its truly an Omega caliber inside.

Do you think that it's best not to wear it till he doesn't get a service?

Why better not send it to Omega? I saw the price for a gold plus gold bracelet, non chronometer is 800 euro.

a good independent watchmaker will probably cost half or even less then omega , but if you want to send it to omega then i don’t see why not .

Here is the small mark near the Crown. It's the Helvetia head.
I'm very interested to find some infos about the Ref 7188. It's nothing on the internet. Why it has Rhodium on it, is it original or?

I will look for some independent watch makers. But who will refurbish the Case and bracelet? The watch maker doesn't do it. That's why I was thinking about Omega s full restoration package.

That is quite a cool piece, I really love this ultra thin Cal 71x watches, especially the gold ones which are quite few and far between.

White gold is rarely brilliant white and tends to have a yellow hue which is why it is usually rhodium plated.

I thought the same. White gold watches are often rhodium plated and therefor they are a PITA to restore. No way to amend scratches - you would have to replate the watch afterwards...
Either the watch is veeery rare or in perfect condition - otherwise pass.
Better to buy steel or platinum (if you can find one)
