Sinn 756 III Limited Edition Chronograph - Automatic, 40 mm (measured without crown), complete set! Sinn Reference Number: 756.031 Date of First Purchase: April 11, 2018 (Germany) Limited Edition: 1 of 75 pieces! Rare Sinn 756 iii Duo-Chronograph featuring AR technology (inert gas filling with a desiccant capsule). The watch is fitted with the original full-length Sinn mesh bracelet, suitable for a wrist circumference of up to approximately 21 cm. In very nice cosmetic condition with only slight signs of wear and minor scratches, primarily on the case back (contact marks from the steel bracelet). During our test on the time scale, the watch ran very well at approximately +3 seconds per day with an amplitude of 262 degrees. All functions work flawlessly; the chronograph resets cleanly, and the reset mechanism works perfectly. It comes as a full set, meaning that in addition to the watch, the box (including the outer carton), the strap tool, the booklet, and the Sinn warranty card are all included. All watches are held in our inventory, so please contact us in advance if you’d like to view one. You will, of course, receive a proper invoice for your watch.
