Cartier Tank 41 x 31 mm - What Is the Difference Between the Solo XL and the New Must?

[BluePortuguese]

Hi there,

Am trying to understand the difference between the "Cartier Tank Solo XL" and the new "Cartier Tank Must watch, extra-large model".

I understand that they are both the same size and both have an automatic movement with date display...?

Can you help?

Thank you.

Cheers
