Heuer Monza 150.501
Heuer Monza 150.501 / 17 Jewel Cal. 15. 1975 / With pulse- and tachymeter scale

The Monza has a truly rich motorsport heritage. Its very being was the result of Niki Lauda winning the 1975 F1 title for the Heuer sponsored Ferrari team at the Italian Grand Prix, on the Monza track (Lauda placed 3rd, with Ferrari teammate & fellow Heuer ambassador, Clay Regazzoni finishing in 1st place). Jack Heuer wanted to celebrate Scuderia Ferrari’s title win, especially as it ended an 11 year dry spell since Ferrari was last top dog in 1964. The result was the Monza, sold as a limited edition in a miniature red racing helmet bearing Lauda’s name. Its design was heavily influenced by the Carrera case and was available in black anodised or chrome finish.

This particular example was sourced, rather appropriately, from Italy and is in almost NOS condition. It’s a beautifully balanced design and the hour lume markers have a rather pleasing patina to them.

  2. i have this watch. its got a scratched up face and no band. its not running right now, but i think it just needs a battery. any idea what its worth now and how much to restore it?

    • Joe, It’s very difficult to value a vintage piece without seeing it in full. If the actual dial is scratched, that is bad news, as it significantly devalues a watch, if it’s the acrylic glass, this can be replaced more easily. Parts for these watches are not easy to get hold of, your best bet is to send it to TAG Heuer for assessment. They will inform you of any available parts and cost of restoration. A ball park figure (if dial is required it could easily be northwards of £5-600 inc. a service). These watches are automatic, they are not powered by a battery, give the watch a gentle shake or wind the crown clockwise to see if it still works.

      I’d suggest your first step is to ask for help/guidance on http://www.chronocentric.com

  3. Very nice watch! I’ve got the same model imported from U.S. and there are some differences showing that IMO yours was “pimped” a little.
    1.case – if you look at Bohnam’s catalogue you will see that case is sort of “brushed” metal. So is mine, I don’t see it on yours
    2.crown – it was not marked with logo originally
    3.crystal – yours seems too high, original is ca 1 mm above case
    back – engravings very deep – like corrected. and should have serial number between 150.501 and “swiss made”
    The rest – especially face and hands – flawless and in good places (sometimes they are mixed). Congratlations and enjoy your beautiful time piece!

    • Thanks for your message Tomasz,
      Your points have solved another strange Heuer mystery! I always wondered why there were different case backs on the Monza models. My research shows this… I believe the differences you note can be easily explained. The Monza was originally meant to be a very limited run aimed at a younger clientele, it was based on the Carrera but at a reasonable price point with ‘cheaper’ components. (Brass case & unsigned crown – an odd choice give the Cal. 15 movement). In fact it was manufactured for longer than expected (to c1977), most probably due to popularity. The ‘later’ models had case differences, (non-brush effect on PVD case) almost certainly due to a different (or altered) case manufacturer. This, is most probably when the Heuer signed crown was added to the package. The Crystal is correct, if you compare the height of the one in the Bonhams catalogue, it is spot on. The shallow angle photograph I have taken emphasises the crystal height . There are two types of caseback for the Monza, on which did not have the serial number between the Heuer shield and ‘Swiss Made’ markings, also with much deeper engraving. These casebacks have been discussed before in the world of Heuers, due to their much deeper milling, but there are significant examples like this that sit with respected collectors that rule out any suggestion of ‘being re-worked’.

      Thanks again for you comments, it urged me to do some deeper research on this model and this is another ‘Heuerism’ that has been explained !

      • You might be right. After closer examination I admit – my crystal is of comparable height. As far as cases are concerned – I’ve read about “economy” version – brass PVD coated but I don’t think it’s a case in Bonham and mine. I’ve written to Tag Heuer trying to find some more info about my piece, they told me it was manufactured in the end of 70s’ which now I doubt – auctioned item dated 1975, lot No. starts with 3556, mine 3595, so practically they might have been twins! So forgive me my enthusiasm – I just fell in love with those Monzas and I’m still in “endorphine phase”. I try to gather any piece of info on it, that’s how I came here. Still lots of learning in front of me 🙂
        All the best,

      • No problem Tomasz,
        Part of the joy of Heuers is their ‘oddities’ whose explanations often require a combination of detective work, educated guesswork and comparison of other mint examples. Many Heuer models (Autavia for example) have cases manufactured by two companies, and it’s an educated guess that this may well be the same for other models.

        We Heuer-ists learn something new every day!

  4. I’m the original owner of a Heuer Monza 150.501. It was a BD gift from Mom. Not sure but sometime between 1975-1977. Mine is not a smooth case like this nor the same blk. There is a texture (brushed?) To the case and the blk is thinner, like a stain. It also doesn’t have the deep engraving except for the 150.501 line. The face, hands, shape and color of hands are identical. My serial # starts 3442.

    • That’s a good friend you have! My ‘orange’ bits are still luminous, it’s just that the lume material has aged to this deep creamy/orange colour.

  6. I got this watch as a birthday present in 1976 (in Canada). Brass case with now-degraded black finish. It has a lot of wear and tear which, unusually for me, I am quite proud of – it, and I, have been through a lot together. I live in the U.S. now, and the last time (circa 1996?) I had it cleaned at the Heuer service center (Pro time or something like that) it was expensive and it came back with a warning about being no longer water-resistant. I now need to get it cleaned again, but don’t know a better shop. I’d appreciate if anyone could steer me toward a reliable shop stateside, and I’d really like to have it water resistant again. Btw, the gals love this watch…!

    • Great story Grant. Many North American Heuer collectors recommend Craig at http://www.chronodeco.com – he’ll be able to sort out your Monza.

      • Thanks for the tip – I’ll follow up. I have my father’s 1960ish Omega Seamaster that needs cleaning, too, and I’ve just been procrastinating. The vintage autos are all lovely timepieces.

  7. Great info on this site. I have one with serial starts at 3363. Any idea of age? The crown does not have Heuer on it.

    • Hi Tommy,
      Thanks. Unfortunately I’ve no idea of the age from the serial numbers. Heuer didn’t keep records of serials & years, and it’s only when collectors started gathering serials for certain models that they could be dated. There is no ‘serial list’ for the Monza, as far as I know.
