Extremely rare NOS vintage Certina Chronolympic watch case Ref. 487 3904 41.
This is the last of three I had for sale / Trade. The other two went quickly!

The case is near mint. One side still has the protective laquer and the back has the protective plastic sticker still in place. The glas has some scratches and it shows dust all over (after almost 50 years....)

This very rare case is the same as the ETERNA Tri Compax FTP 154 with the Valjoux 726 movement. In fact the glas has the ETERNA sign.
The "ETERNA" logo and the "154FTP" have been milled out of the case back and replaced by "Certina". Some say that the Certina 29-062 movement here is based on the Valjoux 728 (I've seen a picture with that).

From what I found in the Internet there were only about 100-200 of this watches sold as CERTINA CRHONOLYMPIC.
This is a great opportunity to rebuilt your valued CHRONOLYMPIC or ETERNA Tri Compax.

I am willing to take offers to trade if you have a chronolympic movement, dials (or Certina diver dials).
See also my other ebay articles as I have other NOS Certina Chronolympic cases to sell.
