Hi,
Recently finish servicing a Titanium 820.213. For me looks really beautiful! Although you can see that time has passed... Well is on eBay.de but wanted to let you know in case a connaisseur wanted my piece.

Here is the link and for everyone safety would like to use eBay or Chrono if you ask me (small commission). Just send me a message if you are interested and we can discuss, is going to be there 3 says I'm auction but assume the price is higher (don't have a clue of actual value), but the full service and replacement parts were not cheap. .
Or search for: "extremely rare -1980s Tag heuer titanium 820.213" in eBay.de

Have a good day and be corona wise!
David
