it will make a great companion to my 5054G.
The Lange measures 37.5mm in diameter and 9.5mm thickness, whereas the normal version measures 35.9mm.
The Patek 5054G is a bit smaller which measures 35.5mm in diameter and 10mm thickness.
Here are some comparison picture of my new Lange 1815 up/down Walter Lange LE and my 5054G. Which one you guys like more?
