CASE: the 43mm stainless steel bead-blasted case is in extremely good, collectors-grade shape. The signed crown is original and screws down. There are no scratches that I can see. There is a small spect on the bottom left lug; it’s just a black mark from storage in its case, and will rub off with enough patience and effort. The crystal has no marks, nor does the bi-directional rotating bezel. The H-link bracelet is also basically flawless, with specks from the case as well which, again, should rub off. Currently, the bracelet can accommodate my 7.25” wrist, but there are two extra links in the box, so presumably that gets close to handling a 7.55” or so wrist. It has a screw-down caseback; I know that denotes something in terms of when it was produced, but I don’t know what. Overall this is in incredible aesthetic condition.

DIAL+HANDS: Without flaw. The lume has aged darker on the markers than the hands but everything glows and fades identically. There’s no mark I can see anywhere, and everything’s crisp and original. The date wheel seems to be in German.

MVMT: The Lemania 5100 is in excellent shape. I don’t know the service history, but it’s currently running well, keeping nearly COSC time, and the chronograph starts/stops/resets as it should, ditto the quickset day/date.

This watch comes with its original box, which includes what I presume is the original Sinn manual for the Lemania 5100.

Price is $3200 net to me. Happy to answer any questions, provide as many references as are requested, and arrange shipping/payment methods with the buyer. Thanks for looking, and to Jeff/CT for the space+community.
