For sale only, Sinn 556A, in good working order, with kit, on bracelet.

Asking $750, which includes USPS USA shipping (insured, sig req) and all PP fees. Feel free to make an offer, worst I can do is say no.

Included Warranty Card (expired) indicates that this was purchased from Watchbuys (USA) July 2013. It keeps very good time -- when I started tracking it against, it was showing a loss of less than -1spd. That said, I've owned it for a number of months, and have not had it serviced. I purchased it used and it did not come with any service history.

It's in fairly decent shape -- normal scuffs from 6 years of irregular use on the bracelet, no scratches on either front or back sapphire, AR on front sapphire is flawless. The case is showing some scratches, scuffs, and scrapes, with the worst offenders at the top of the case, between 11 and 1. In use, did not bother me at all, especially for a GADA tool watch. I was surprised when I saw the pictures I am posting here -- looks much worse than it shows IRL, to the naked (or vision corrected) eye. Still makes for a great GADA, or "beater" piece.

Not shown: full kit. Outer box has some tearing and lifting on the back from where it looks like tape or a label was too hastily removed. Inner leatherette display box in perfect shame. Comes with owners manual, original sales/warranty card, 2 extra links for the bracelet, and the Sinn springbar tool.

Bracelet is adjusted for 7" wrist -- with 2 extra links and clasp microadjustments, should fit up to 7.75" wrist or so?
