On the recently discussed topic of topicality/patina, one of my latest additions to add to the party...

This one came via Mexico and is now the fourth Chronomatic Monaco (157189, 200, 201, 213) without a back case toolno33 marking. I think there is a strong likelihood that such watches were the batch produced pre-production and pre March 1969 launch and which were then sold after the event. I also suspect that initially Heuer had not bargained for watchmakers being nonplussed about how to open the watch, i guess that was what led to the tool stamp coming in shortly after...

Although the picture doesn't show it (i need to wait for some much needed UK sun first!) this heavily patina'd back to brass dial has a tendency to shine brightly when it catches the sun. It's certainly the perfect "beater" Chronomatic, fear of future degrading is not on the agenda!

Cheers
