Let me start with saying i'm a fan of the Monza, I own a Cal.15 PVD model myself and love it. ( I was sadly also a teenager in the 80ies / Mullet hairstyles and a cross over of Synthersiser music and later Hair Metal cloud my past too! LOL )
The Cal.12 example you have photo linked is in lovely condition and i would say it is a very desireable piece with its original looking strap/unsigned buckle, original manual and original (super rare) hang tag. The other pieces look to be from later items - i guess the bracelet to be a Pasasdena item and the Heuer case to be from the Re-issue model period 90's-2000.
These Cal.12 pieces are quite a bit rarer than the Cal.15 model and in rarity we often see prices increase. The reason Monza models dont command the prices and attention other Heuer models demand could be because they were made as a 'Bugdet' model. They are made of cheaper metals and then PVD covered or chromed to finish the case work. Some purists see Stainless or the less popular Gold to be the only metals worthy of strapping to the wrist.

For Arno : I have never seen a chrome case Cal.12 Monza. Did they exist or were all Cal.12 Monza's treated to the PVD process?

I hope you buy and then enjoy this truely lovely piece Richard.

: Morning

: I'm posting a picture of a 110.511 Heuer Monza for the site experts
: and am looking for feedback to confirm or not if this is an
: original proper example of the watch as stated in the title? It
: looks ok to me but i havent seen one with the above ref before
: and the sub dials and HEUER MONZA wordng all appear to be
: slightly different on other vintage Monzas that i have seen
: (some have just HEUER or just MONZA on the dial). Can i asume
: this is a Cal 12? It comes with the PVD strap in addition,
: although again i'm not 100% if that is original as i havent seen
: one before and the originall booklet and box, so am hopeful this
: is an original and genuine exmample.

: On a different slant, why is it that these watches do not have a
: simnilar following to Camaro's, Autavias etc? They appear, to me
: at least, to represent good value for money at present and to my
: eye seem to be a very good looking watch, which still looks
: fresh and wearable.

: Very grateful for any feedback inc general history on early
: Monzas...

: Thanks
