This is a Cartier Must Tank quartz model from the 1980s. The buckle and strap are aftermarket. It is a working watch, but the battery was replaced about a year ago, so it may run out of battery during shipping. The crystal is slightly cloudy, but personally, I didn't find it difficult to see. I purchased this from a vintage watch shop a few years ago. This product has not been re-plated and is said to have the original plating from when it was released. Although it is slightly faded, the original plating is very rare, and I was told it is an extremely valuable piece. You can enjoy the vintage atmosphere as is, or you could have it re-plated. (I personally prefer the original, as it seems a shame to re-plate it) Size: 23mm x 30mm Strap width: approx. 17mm Due to the nature of branded goods, returns are not accepted after purchase. Please understand the current condition, including the operating status, before purchasing. It will be shipped via Yu-Packet Post Mini. Instant purchase OK While significant price reductions are difficult, I am open to some price negotiation.
