Heuer Cal 12, '20'?

Strange one...clearly stamped '20' on the baseplateNoticed this on the C12 I removed from the Montreal I picked up a few weeks back.
My main camera's being serviced so the photo was taken using my Iphone with a loupe attached - so, maybe not the best quality :-(
Also visible is the standard 'SX' and 2 bars on the edge just below and left of the '20'.
I mentioned it over @ OTD here
Arno replied saying he'd seen one also in an Autavia 1163 MH with a much better photo in his book, pages 66/67.
First thought was maybe a high beat prototype, however I clocked it @ 21,600 vph using the iphone app Kello.
So, another Heuer mystery :-)

Breitling Auto-Time 1651

Something a bit different.
The vintage Heuer motor racing timers are getting so expensive now I was delighted to stumble across this beauty over the weekend.
Love the strong colours.

Heuer Montreal, work in progress

I picked up this Cal12 Montreal on eBay last week.
Not working and in need of a tiny bit of TLC.
Anyway, turns out it needs nothing more than some case clamps to secure the movement, correct sweep hand, fix the chrono reset and a case tidy up.
As you can see the case was a bit beat up.
Here's the work so far...
Tidies up pretty well though with a few hours work :-)

TAG Heuer Monaco CS2110 - the watch that sparked an obsession!

Back in 1998 I was into Breitlings and not even vintage ones!
A job move to Amsterdam saw me passing through Heathrow Airport on a fairly regular basis.
One day I was on my way to the aircraft, drifting by the tax-free shops, when something stopped me dead in my tracks!
It was the new re-edition Monaco ref CS2110.
WOW!!!
There were pictures of Steve McQueen and Jo Siffert on the back of a motorcycle looking like the coolest guys on the planet, ever!
I had to have one.
Subconsciously I must've seen Monacos before because it just seemed the perfect watch and felt 'right'.
This is the watch that led me down the vintage Heuer path to where I am today.
Anyway, this week I got a new arrival, and it looks and feels superb.
I've had re-editions before and haven't really been that keen to be honest but the CS2110 is different and I love it :-)
Looks even better on a vintage corfam.
The series was limited to 5000 pieces and recent demand has seen prices rise steadily so my advice is to buy one now before they go too high.
