Up for sale or trade is a Sinn UX (EZM 2B) Hydro on Bracelet Limited Edition Model with the screw down crown at the 10 O'Clock position instead of the 5 O'Clock position of current models. https://www.watchbuys.com/store/pc/Sinn-UX-EZM-2-B-Hydro-on-Strap-p381.htm https://www.sinn.de/en/Modell/UX.htm (Have not found a link of this exact model for sale. Subtle differences in the dial print on this watch with the crown position is what makes it a special edition.) Location: California, United States Condition: Watch is in very good condition and it was sparingly worn since I bought it 4 years ago. No significant scratches or wear to the bracelet or case that I can find. Very minimal scuff of black dial paint at one location that I did my best to capture on the pictures. The common problem with this particular Sinn model is development of a bubble in the oil, which has occurred on this watch. You can read about the problem and causes within this forum link (https://www.watchuseek.com/threads/sinn-ux-bubble-appearing.5187795/). Despite advice and attempting to reduce the bubble through recommendations online, Watchbuys and Sinn customer service, the bubble remained. Confirmed by Sinn, this means that the first service will be required for the bubble to be eliminated (this service is recommended every 5-7 years anyway and includes battery along with oil change). The following link from Sinn shows the service and pricing for this watch (https://www.sinn.de/en/Download/Sinn_ServicePriceList_170828.pdf). It should be noted that the small bubble does not and will now affect any functionality. Watch comes with original watch case, bracelet box with tool/extra links/extra pins, and used Erika's Original olive and red strap. No warranty card or manual.

Please feel free to reach out to me with any questions or concerns through private message or by leaving a reply on this post. I have done my very best to show and describe the true condition of this watch, and want nothing more than a happy recipient. So please ask questions if you have them because purchase is final.
