Today we go back into Jatucka’s archive and share a cool prototype Omega that Roberto unearthed…

I am pleased to present to you all a particularly unusual and rare Omega Seamaster Chrono.

I actually believe it is a Prototype of Seamaster Chrono Ref 176007. The Omega Seamaster Chrono Ref 176007 in its final version was fitted with a light blue “electric” dial

Here is a production example of the watch.

The movements in these watches was an Omega cal. 1040, derived from the Lemania 5100, with the characteristic ‘Central Contamination ‘ function. The watch’s serial number was on the rotor .

The reference number is stamped inside the case back with these watches.


Here is the watch that I found…

I think it is, as I said, a “test” watch or prototype of the Reference 176007.

It features a dial without the usual Omega logo and Seamaster dial text. Note also that the internal tachymeter scale is also absent from this test piece.

The dial has a magnificent white “cream” shade, with the black contrast counters.


The Case Back shows the classic Omega Seamaster Logo.

The movement is not marked in any way, and it does not have any serial number or markings of any description.

The inside of the case back does however have the reference number in it.

There was also an interesting Reference Number ( 20 ) inscribed with an engraving pen or some such tool.

I hope that these very short notes have been interesting to you. To me, this is a very interesting watch and it was a real pleasure to share it with you.

Thank you all for your attention!
