For your consideration my Sinn U50 in the regular (non-regimented) version in excellent condition with full kit, papers and a black Sinn silicone strap with the OEM deployant diver's clasp, sized for a 7.5" wrist. It was purchased by me directly from Watchbuys in the autumn of 2021. This U50 features the extended power reserve of up to 56 hours. Timekeeping is superb at between +1.6 and +2.3 spd, and the bezel action is crisp and positive. Case, lugs and crystal are clean, with no obvious or significant dings, dents, scratches or swirls. It will ship on the OEM Sinn silicone strap and deployant diver's clasp. Please consult the detailed photos below for a fuller guide to its condition. MSRP for this model is now USD 2470.00. I am asking USD 1840.00, or USD 1695.00 for the watch head only. Insured shipping and any fees will be the responsibility of the buyer. The watch and I are located in Canada. Trade options include tool or sports watches from Sinn, Oris, Longines, Nomos, etc. I am not looking to add on any trade. I sell watches rarely but have feedback here and on other watch sites and the high-end audio forums that I more generally frequent. Please feel free to contact me with any questions and thanks for OF for the space.
