Excellent condition 1951 IWC Mark XI. Full military mark. On the case back it has arrow mark and issue numbers. On the dial, arrow mark, and circle T. Hack setting Cal 89 movement in excellent running condtion. Case is in great condition, never been polished. Dial is in very good condition. Hands are in fine condtion. The lugs are modified to use spring bars not fixed bars so you can put any strap on it. I do have other pictures via email. Asking $3300. I have many references upon request. Please email me if you have any other questions. Thank you. Tom. Will add some more pictures tonight.
