Cartier Must Tank LM, manual-wind, with international lifetime warranty, fully serviced by the manufacturer, purchased in 1981

This is a manual-winding model of the "Must Tank LM," a long-selling Cartier timepiece.

The Must Tank features a sterling silver (925) case with a gold coating known as "Vermeil."
This piece is from the 1980s and is equipped with a manual-winding movement.
As the Must Tank transitioned to battery-powered (quartz) movements in the 1990s, manual-winding specimens are quite rare.

The dial is the popular ivory face with Roman numeral indices.
It was replaced during Cartier’s complete service and features "SWISS MADE" at the 6 o'clock position and the "CARTIER" secret signature within the 7 o'clock index.

The hands were also replaced during Cartier's complete service and are now blue steel hands.
The blue steel hands have a beautiful luster that shines elegantly depending on the angle of the light.

While manual-winding watches require manual operation, the crown is easy to grip and use, making this a recommended choice even for those new to manual-winding watches.

The Must Tank LM (Large Model) was originally released as a men's size.
Its compact size makes it suitable for both men and women.
For men, it is best suited for those with slimmer wrists.

With its classic and refined atmosphere, it can be worn for any occasion.

Operation Guide

Manual Winding: Rotate upward in the normal crown position.

To wind the mainspring, please turn the crown slowly and carefully in an upward direction.
It will feel light when you begin, but will offer more resistance as it becomes fully wound.
Please be careful; forcing the crown past the stopping point may break the mainspring.

How to Pull the Crown: Insert your fingernail between the case and the crown and pull gently.

Pulling the crown too forcefully may cause it to come out, so please handle it with care.
To prevent bending the crown, please remove the watch from your wrist before operation.
Handling it gently will reduce the strain on the crown.

Time Setting: Pull the crown and rotate downward.
