I am so excited that after sending my watch out for repair 4.5 months ago, mybwatch has returned…read more It came back with new seconds hand, new crown and wind mechanism and all wayer seals were changed. I opened the box, and at the first wind i could tell the winding mechanism was so smooth just as when knew. By the way this watch goes to the pool, beach and it is a daily beater. I have to say that Sinn technician and customer service worked very close to let me know when the watch was received, when it went to service, when repairs were completed and as soon as my visa payment was processed. My watch was shipped out of Germany on 3/18/24 to arrive at home on 3/21/24. While it was a while to wait for repairs, i believe it was well worth it, as my U1- T SDR is a limited release watch and i couldn't think of any other place to have the repairs done than the place of birth, literally of where my watch was made. For approximately $345 US
