Sinn 900 S Pilot UTC Flieger Chronograph Automatic in 44 mm (measured without crown)! Reference number: 900.020 Age of the watch: approx. 2015 Used condition with slight signs of wear and scratches, especially on the bracelet. The watch is fitted with the original black tegimented steel bracelet in a good length, suitable for a wrist circumference of up to approx. 19.5 cm (replacement links are available from Sinn for a small fee if this is too short). In our test on the timing machine, the watch ran very well at around + 2 s / d with an amplitude of 308 degrees. All functions are flawless, the chronograph resets cleanly and the reset works perfectly. Delivery is in the original Sinn box with outer packaging. All watches are in stock, so please contact us in good time if you would like to view them. You will, of course, receive a proper invoice for your watch.
