Howdy, Up for sale is my Sinn 356. Here are the specs: Case Material - Stainless steel | Case Diameter - 38.5mm | Lug Width - 20mm | Lug-to-Lug - 46mm | Case Thickness - 15mm | Water Resistance - 100m, low pressure resistant | Movement - Sellita SW500, handwinding, hacking, 28,800 vph, anti-magnetic as per DIN 8309 | Crown - Screw down | Power Reserve - 46h | Crystal - Domed sapphire w/ AR coating |  To create this watch, Sinn designed a silver guilloche electroplated dial which is UV resistant. If you've seen the Sinn 356 Sa Flieger II with the copper dial, you will recognize the technique used to make this dial. The highly domed sapphire crystal glass is ground out and carefully polished using a complex process involving an approximately 5 mm solid blank with five different curvature radii. Another interesting feature is the silver day/date wheels which beautifully complement the dial.  Included is a beautiful shell cordovan strap from two stitch straps in excellent condition: [https://www.twostitchstraps.com/en-us/collections/shell-cordovan/products/full-stitch-whiskey-shell-cordovan-leather-watch-strap](https://www.twostitchstraps.com/en-us/collections/shell-cordovan/products/full-stitch-whiskey-shell-cordovan-leather-watch-strap) I am asking $1699 shipped and insured via PayPal friends and family or Zelle. Included but not pictured are the box and papers (I am out of town). The watch is in good condition with typical signs of wear. Warranty card dated for 2019.
