IWC Mark XI Ref. 6B/346 For The Australian MOD, 1957 Rare


This IWC Mark XI is in excellent condition considering it was a military issue watch serving in the Australian air force.

The case is in good condition with some superficial scratches, no dents or dings.
The matte dial surface is clean with light and attractive patina. The lume on the dial and hands seem original.

The dial, caseback, and movement all have the broad-arrow mark. The inside caseback is stamped “IWC” in a circle, a feature only on issued Mark XI examples.

The Australian air force issue, with fixed lug bars in such good condition is fairly rare.
