Hello - Interested in selling my Sinn 556i on a brand new, unworn Sinn leather strap with inner and outer box. Watch is in perfect mechanical condition with crown, date set, time set, and winding all working flawlessly. Cosmetically it is also in excellent shape with no marks on the outer A/R coating of the crystal and very minor and very few marks to the case at all. I am asking $900 which includes USPS Priority Mail shipping to the USA. Will ship internationally but you need to ask me how much more that will cost. Payment is accepted via PayPal, Venmo, or Zelle and watch will be shipped the business day after funds are received - I can probably ship on a Saturday but it will be sent no later than the following business day. I have feedback here, on WatchUSeek where I am 'cmford' and on eBay where I am 'cmfordaccount' - thanks for your interest and let me know if you have any questions at all. Watch details: • Watch diameter (mm): 38.5 • Watch height (mm): 11.0 • Lug width (mm): 20 • Lug to lug (mm): 45.5 • Weight - head only (grams): 65 • Water resistance: 200 meters • Case back: Transparent • Case finish: Satinized • Case metal: Stainless steel • Dial color: Black • Front crystal: Sapphire • Movement: Automatic mechanical
