Gold content in a Vintage Omega Genéve 18k gold dresswatch 166.037 from 1968, 35mm???

Hello Don, Yes I agree, but knowing the gold weight helps to asses the value of the watch.
I can research most of the other factors, I was just looking for some help with the gold weight.

Too many variables to give you a figure for any particular reference.

Rule of thumb that I use is no more than 50% of total weight of watch (without band, of course) is the gold case. Then take that times fineness of gold to get gold weight.

Smaller men’s dress watches (say 33mm or less) are likely to have significantly less case weight than the higher end models like a Constellation or Seamaster.

The national production cases from the US and South America would likely have less gold than an equivalent Swiss case, while UK or French cases tend to be equivalent to the Swiss weight, if not more.

It’s a very inexact science, as some watch cases even have base metal rings built in to secure the movement inside the case. Seamaster DeVilles have these.

Hope this helps,

but it’s only 1/5th of the value (technically)

case design, dial and movement condition. Model and brand name all add up the price

maybe 1 ounce of 24kt mixed down to 18kt. 35 grams on or about

doesn’t matter. 5 people will all ask different prices on the same watch

check EBay’s completed auctions for a end value you might expect to pay

@St.
You’re right in thinking the gold scrap weight is the base value for the watch.
Then, assuming it works, you can add some for an Omega movt.

To answer your original question, I believe the Seamaster you note is likely to be lighter than most Constellations ( but perhaps more similar to similar shaped hidden crown Connies)

Here is a thread that gives some accurate info about a gold Constellation.

however, the ultimate value of any watch is not only in its intrinsic value but in its desirability and the condition of the case and dial.

I have no interest in helping a new member publicly calculate the scrap value of a collectible Omega.

Gold is at an historic high right now. Your watch is not an investment. If you really love vintage Omega, stop thinking so much about melting it down and find a watch that will give you joy.

Dan S

Because it is not a good investment. In time, you'll understand.

And if you don't understand why a question about melting down a watch for gold might be offensive as your first post, you have not spent enough time on the forum to read the room properly. No questions about movements, styles, quality, dial variations, etc. Just gold value. It sends a clear message.
