CASE: 40mm bead-blasted titanium is in excellent shape with very few marks or signs of wear. Bracelet has divers extension clasp and will fit up to a 7.75" or so wrist. Signed screw down crown is excellent and original. Bi-directional clicking bezel rotates as it should. Caseback etching is entirely clear. Please look at pictures; they're the best description.

DIAL+HANDS: Excellent, no flaws that I can see, all original. Again, please see pictures.

MVMT: The Lemania 5100 is running close to COSC and has been for a long while. I won't open up the caseback simply because this is an AR model, meaning Sinn sealed the watch with Argon gas, which is supposed to aid in keeping the watch free from water (I'd recommend reading this for more info: https://www.sinn.de/en/Ar-Dehumidifying_Technology.htm). Everything's correct and as it should be: the chrono starts/stops/resets, the date quicksets and flips at midnight, and, again the watch is keeping excellent time. I don't know the service history of the watch, so a service is suggested for regular wear, but clearly this thing has been incredibly well maintained.

The watch comes with its inner+outer box, manual, and guarantee paper. It also comes with a 20mm Sinn strap with signed Sinn buckle. These are getting harder to find, in any condition, let alone as nice as this with all the extras. Please ask any questions you have.

Price is $7500 USD net to me. Happy to answer questions, provide as many references as are requested, and to arrange shipping and payment method that works for both buyer and seller. Thanks for looking, and to Jeff/CT for the space.
