Dear Gigi,

Thanks for your input, but you are wrong, it could look like your cheap looking brachelt on your El Primero, but indide its a Prototyp Calculatur origl Heuer signed steel brachelet....( it was even been Filed at the last Link, before the endpieces so it would fit a Monaco case at the downside too.) i think it could been in the factory a project bracelet between Monaco Mark 1 version Bracelet and Mark2 - 1970ty version.

I ask you;
Why sould Heuer as supplier of several Heuer Chronos put a such poor looking steel bracel on one of their watches for the movie- set??? Doesnot make sence too.

You must realize that fotographers on the movieset were focused on shooting the Actors or Steve Mc Queen or just the Racecars...so watches were very secondary and not in the camera focus and so with often not sharp or in a central position of the picture. As Steve McQueen was no Heuer Ambassador for the Heuer Monaco watches on the movieset at that time period, so the Press - fotos were he is posing/ holding his right-wrist with the watch to his neck and you see him claerly waering the blue Monaco were made later for the movie Poster and Press releases.

Steve McQueen gave Helmut Kelleners this watch in friendship at the end of the movie - shootings as Appreciation for his Commitment at the movie - set.

Here is a close up of the Monaco on the Calculator bracelet from the day in 2009 as i bought it from Helmut Kelleners,
