This Big Blue is very hard to find and are getting more and more collectible. I would not be supprised if after the re-edition of the Omega PloProf this would be next.

    The Big Blue is one massive chunk of metal and the caliber 1040 inside of it is Omega’s work of art. One of the best automatic chronograph movements Omega (Lemania) ever produced. Period.

    The 176.004 is amazing. That blue bezel’s a killer – along with size, it sets the model apart among the 1970s Omega chromos. Supposedly there are NOS replacements in circulation (unfortunately the originals are prone to cracking) but pieces presented as ‘mint’ usually have rendition issues. Great you have the 1186 bracelet.
