Mario,
: I am new to Heuer and to the Siffert, so I didn't reply as I didn't
: want to provide incorrect information. But now you have taunted
: me into replying and potentially revealing to the entire
: community that I don't know diddly.
: I would recommend that you peruse these two pages - scroll down to
: the "Automatic Autavias" sections to see the
: differences between executions. Or do a search for Siffert on
: each page.
: http://www.onthedash.com/Guide/Master_Reference.php4
: http://www.onthedash.com/priceguide.shtml

: So far, I'm safe. Here's where I may go astray - the 1163
: (automatic) Autavias which have the white dial with black
: subdials, blue chrono second hand and blue accents are referred
: to as "Sifferts". Some even refer to the manual-wind
: Autavias with the same coloration as Sifferts, but generally
: they say Siffert colors.

: There were several 1163 Sifferts sold from internet postings in the
: past 2-3 months. I believe the lowest price was around $6500 and
: the highest around $8800. I do not believe any Chronomatics have
: been posted for sale in that same timeframe (Sifferts or not)
: except for 1. The one I have seen is on Nic Green's new site and
: no price is listed (smart, I believe). He also has a Caliber 12
: version listed at £8000 which should serve to help you feel
: good about buying that watch if it is still available. If not,
: Nic's got one for you!

: I hope this helps.

Hi Mike,
I should taunt you more often! ;-) Your info proved very useful for the Master Reference Guide on the Onthedash.com site but the Price Guide is very outdated, from 2007! I wish I could get a blue faced 1133B Monaco for $6,000! And the Siffert Autavia isn't even on the top tier AAAA list. Someone should update that price list, hint hint! ;-) (that was to On The Dash not you Mike!)

The Autavia I'm looking at is the Mark 4 according to the master guide so should be valuable. Only thing is that the examples they show have the Calibre 11 instead of the 12, which is in the one I'm looking to purchase. I'm assuming it should be just as valuable.

Thanks for taking the time and I will post a photo if I decide to take the plunge with this one! I recently won an auction on Ebay for a very nice Heuer Regatta so I'll post the photo of that one once I get it. It is missing the original steel band so let me know if you hear of anyone having one, I'll post on here about that as well.
All the best,
Mario
