Cartier Premast Square Tank LM

The Must Tank, a watch that was historically and remains popular, was released to the general public as the "Tank Louis." The rare early Must Tank, without the "Must de" inscription, is known as the Pre-Must Tank and is considered a mysterious and unique model even within Cartier's lineup. This particular piece is a rare square LM model. What's interesting about the square LM is that, unlike the SM, it doesn't use the cal.78 movement; instead, it features the larger 7040 movement. It would be a fascinating watch, whether as an entry-level piece or a casual, distinctive timepiece. Regarding its condition, it shows minimal signs of use, and the original plating from that era is well preserved. To maintain the original plating, it has mostly not been polished, so there are minor scratches, but I believe the overall condition is good. Both the hands and glass are clean, and for a Pre-Must, it appears to be in remarkably good condition. 《Product Details》 Brand: Cartier Product Name: Pre-Must Tank Square LM Material: YG Model Number: Serial: 51760000#### Movement: Peseux 7040 Color: Yellow Case Diameter: Approximately 27.5mm Wrist Circumference: Up to 17.5cm Band: New Aftermarket Buckle: Original GP Accessories: Our warranty card Maintenance is available at our store even after purchase.
