Cartier
You can buy a new Tank or you can get this: A extra flat Tank Louis in the original size driven by the FP21 movement. No, this would be a Paris dial one, but what you also get is the super rare Pre CPCP flinque/guilloche dial, which I personally love. If you plan to get a Tank, get a 1600 (this is also the predecessor of the CPCP Tank.)! Why? It's rare and it's super nice.

Condition
About the watch: Worn conditions, some scratches here and there. Screws are looking good, dial has no flaws or mentionable oxidations. Caseback has some scratches, crystal has a mini scratch close to the Cartier logo. Very very good condition and a very thick case, maybe unpolished. The watch is running great on the wrist, it winds and really is accurate. Since the service history is not know, feel free to ask for a service if you want to have one. You will receive the watch in a Cartier service pouch.
